A capital city, or just capital, is the municipality holding primary status in a country, state, province, department, or other subnational division, usually as its seat of the government. A capital is typically a city that physically encompasses the government's offices and meeting places; the status as capital is often designated by its law or constitution. In some jurisdictions, including several countries, different branches of government are in different settlements, sometimes meaning multiple official capitals. In some cases, a distinction is made between the official(constitutional) capital and the seat of government, which is in another place. English-language media often use the name of the capital metonymically to refer to the government sitting there. Thus, "London-Washington relations" is widely understood to mean diplomatic relations between Great Britain and the United States. -Terminology and etymology- The word capital derives from the Latin word caput(genitive capitis), meaning 'head', later borrowed from Medieval Latin capitālis('of the head'). The Latin phrase Roma Caput Mundi(lit. ' Rome head of the world') was already used by the poet Ovid in the 1st century BC. It originates out of a classical European understanding of the known world: Europe, North Africa, and Southwest Asia. The phrase is related to the enduring power of the city first as the capital of the Republic and the Empire, and later as the centre of the Catholic Church. In several English-speaking states, the terms county town and county seat are also used in lower administrative divisions. In some unitary states, subnational capitals may be known as 'administrative centres'. The capital is often the largest city of its constituent, though not always. -Origins- Historically, the major economic centre of a state or region has often become the focal point of political power, and became a capital through conquest or federation. Historical examples are ancient Babylon, ancient Athens, ancient Rome, Abbasid Baghdad, Constantinople, Chang'an, and ancient Cusco. The modern capital city has not always existed: in medieval Western Europe, an itinerant(wandering) government was common. The capital city attracts politically motivated people and those whose skills are needed for efficient administration of national or imperial governments, such as lawyers, political scientists, bankers, journalists, and public policy makers. Some of these cities are or were also religious centres, e.g. Constantinople(more than one religion), Rome/Vatican City(the Roman Catholic Church), Jerusalem(more than one religion), Babylon, Moscow(the Russian Orthodox Church), Belgrade(the Serbian Orthodox Church), Paris, and Beijing. In some countries, the capital has been changed for geopolitical reasons; Finland's first city, Turku, which had served as the country's capital since the Middle Ages under the Swedish rule, lost its position during the Grand Duchy of Finland in 1812, when Helsinki was made the current capital of Finland by the Russian Empire. The convergence of political and economic or cultural power is by no means universal. Traditional capitals may be economically eclipsed by provincial rivals as is the case with Nanjing by Shanghai, Quebec City by Montreal, and several US state capitals. The decline of a dynasty or culture could also mean the extinction of its capital city, as occurred at Babylon and Cahokia. "Political nomadism" was practiced in ancient Near East to increase ties between the ruler and the subjects. Although many capitals are defined by constitution or legislation, many long-time capitals have no such legal designation, including Bern, Edinburgh, Lisbon, London, Paris, and Wellington. They are recognized as capitals as a matter of convention, and because all or almost all the country's central political institutions, such as government departments, supreme court, legislature, embassies, etc., are located in or near them. -Modern capitals- Many modern capital cities are located near the centre of the country, so that they are more accessible to its population and have better protection from possible invasions.(See also § Capitals in military strategy) The location may also be based on a compromise between two or more cities or other political divisions, historical reasons, or enough land was needed to deliberately build a new planned city for the capital. The majority of national capitals are also the largest city in their respective countries. Modern examples are Berlin, Cairo, London, Madrid, Mexico City, Moscow, Paris, Rome, Jakarta, Metro Manila, Seoul, and Tokyo. Counties in the United Kingdom have historic county towns, which are often not the largest settlement within the county and often are no longer administrative centres, as many historical counties are now only ceremonial, and administrative boundaries are different. The number of new capitals in the world increased substantially since the Renaissance period, especially with the founding of independent nation-states since the eighteenth century. In Canada, there is a federal capital, while the ten provinces and three territories each have capital cities. The states of such countries as Mexico, Brazil(including the famous cities of Rio de Janeiro and São Paulo, capitals of their respective states), and Australia also each have capital cities. For example, the six state capitals of Australia are Adelaide, Brisbane, Hobart, Melbourne, Perth, and Sydney. In Australia, the term "capital cities" is regularly used to refer to those six state capitals plus the federal capital Canberra, and Darwin, the capital of the Northern Territory. Abu Dhabi is the capital city of the Emirate of Abu Dhabi and also of the United Arab Emirates overall. In unitary states which consist of multiple constituent nations, such as the United Kingdom and the Kingdom of Denmark, each will usually have its own capital city. Unlike in federations, there is usually not a separate national capital, but rather the capital city of one constituent nation will also be the capital of the state overall, such as London, which is the capital of England and of the United Kingdom. Similarly, each of the autonomous communities of Spain and regions of Italy has a capital city, such as Seville and Naples, while Madrid is the capital of the Community of Madrid and of the Kingdom of Spain as a whole and Rome is the capital of Italy and of the region of Lazio. In the Federal Republic of Germany, each of its constituent states(or Länder, plural of Land) has its own capital city, such as Dresden, Wiesbaden, Mainz, Düsseldorf, Stuttgart, and Munich, as do all of the republics of the Russian Federation. The national capitals of Germany and Russia(the Stadtstaat of Berlin and the federal city of Moscow) are also constituent states of both countries in their own right. Each of the states of Austria and cantons of Switzerland also have their own capital cities. Vienna, the national capital of Austria, is also one of the states, while Bern is the(de facto) capital of both Switzerland and of the Canton of Bern. -Planned capitals- Governing entities sometimes plan, design and build new capital cities to house the seat of government of a polity or of a subdivision. Deliberately planned and designed capitals include: These cities satisfy one or both of the following criteria: A deliberately planned city that was built expressly to house the seat of government, superseding a capital city that was in an established population center. There have been various reasons for this, including overcrowding in that major metropolitan area, and the desire to place the capital city in a location with a better climate(usually a less tropical one). A town that was chosen as a compromise among two or more cities(or other political divisions), none of which was willing to concede to the other(s) the privilege of being the capital city. Usually, the new capital is geographically located roughly equidistant between the competing population centres. --Compromise locations-- Some examples of the second situation(compromise locations) are: Canberra, Australia, chosen as a compromise location between Melbourne and Sydney. Washington, D.C., United States, founded as a compromise between more urbanized Northern states and agrarian Southernslave states to share national power. The Compromise of 1790, resulted in the passage of the Residence Act, which approved the creation of a national capital on the Potomac River on land ceded from Maryland and Virginia. Frankfort, Kentucky, midway between Louisville and Lexington. Ottawa, Ontario, Canada, along the boundary between the two former colonies that formed the core of pre-Confederation Canada—primarily English-speaking Upper Canada and primarily French-speaking Lower Canada. Today, this border separates the two most populous of Canada's ten modern provinces, Ontario and Quebec. Tallahassee, Florida, chosen as the midpoint between Pensacola and St. Augustine, Florida – then the two largest cities in Florida. Wellington became the capital city of New Zealand in 1865. It lies at the southern tip of the North Island of New Zealand, the smaller of New Zealand's two main islands(which subsequently became the more populous island) immediately across Cook Strait from the South Island. The previous capital, Auckland, lies much further north in the North Island; the move followed a long argument for a more central location for parliament. Managua, Nicaragua, chosen to appease rivals in León and Granada, which also were associated with the liberal and conservative political factions respectively Jefferson City, Missouri was selected as the state capital in 1821, the year after Missouri was admitted to the Union, due to its central location within the state. It is almost halfway between Missouri's two largest cities, Kansas City in the west and St. Louis in the east, although Kansas City was not incorporated until 1850. Changes in a nation's political regime sometimes result in the designation of a new capital. Akmola(renamed Astana in 1998) became the capital of Kazakhstan in 1997, following the collapse of the Soviet Union in 1991. Naypyidaw was founded in Burma's interior as the former capital, Rangoon, was claimed to be overcrowded. -Unusual capital city arrangements- A few nation-states have multiple capitals, and there are also several states that have no capital. Some have a city as the capital but with most government agencies elsewhere. There is also a ghost town which is currently the de jure capital of a territory: Plymouth in Montserrat. Belize: Belmopan was designated the national capital of the then British Honduras in 1971, but most government offices and embassies are still located in Belize City. Canary Islands(Spain): Until 1927, the capital of the Province of Canarias was Santa Cruz de Tenerife. When the Canary Islands became an autonomous community in 1982, Santa Cruz de Tenerife and Las Palmas de Gran Canaria were both given capital status. There is currently a balance of institutions between the two capitals; the Canary Islands is the only autonomous community in Spain which has two capitals. Chile: Santiago is the capital even though the National Congress of Chile meets in Valparaíso. Czech Republic: Prague is the capital city, however the Constitutional Court, Supreme Court and Supreme Administrative Court are all located in Brno. Estonia: the Supreme Court and the Ministry of Education and Research are located in Tartu. France: The French constitution does not recognize any capital city in France. By law Paris is the seat of both houses of Parliament(the National Assembly and the Senate), but their joint congresses are held at the Palace of Versailles. In case of emergency, the seat of the constitutional powers can be transferred to another town, in order for the Houses of Parliament to sit in the same location as the President and Cabinet. Germany: The official capital Berlin is home to the parliament and the highest bodies of the executive branch(consisting of the ceremonial presidency and effective chancellery). Various ministries are located in the former West German capital of Bonn, which now has the title "Federal City". The Federal Constitutional Court has its seat in Karlsruhe which, as a consequence, is sometimes called Germany's "judicial capital"; none of Germany's highest judicial organs are located in Berlin. Various German government agencies are located in other parts of Germany. India: Andhra Pradesh: Hyderabad is the de jure capital of the state until 2024, while Amaravati is the de facto seat of government since 2014. The Governor of Andhra Pradesh has his official residence in Vijayawada Chhattisgarh: Raipur is the administrative and legislative capital, while the high court(judiciary capital) is located in Bilaspur. The proposed future capital is Nava Raipur. Jammu and Kashmir: Srinagar serves as the summer capital of the state while Jammu is the winter capital. Every six months, the entire state machinery shifts from one city to another. Kerala: Thiruvananthapuram is the administrative and legislative capital of the state, while the high court is located in Ernakulam. Himachal Pradesh: Shimla is the primary capital city. Dharamshala, which is also the headquarters of the Central Tibetan Administration, is the second winter capital of the state. Madhya Pradesh: Bhopal is the administrative and legislative capital of the state, while the high court is located in Jabalpur. Punjab and Haryana: Both states share Chandigarh as their capital city. The city itself is administered as a Union territory. Odisha: Bhubaneswar is the administrative and legislative capital of the state, while the high court is located in Cuttack. Rajasthan: Jaipur is the administrative and legislative capital of the state, while the high court is located in Jodhpur. Uttarakhand: Dehradun is the administrative and legislative capital, while the high court is located in Nainital. The proposed future capital is Gairsain. Ladakh: Leh and Kargil serve as joint capitals of the Union Territory. South Korea: Seoul remains as the capital and seat of the government's branches, but many government agencies have moved to Sejong City. Malaysia: Kuala Lumpur is the constitutional capital, home of the King, and seat of Parliament, but the federal administrative centre and judiciary have been moved 30 kilometres(19 mi) south to Putrajaya. Monaco, Singapore, and the Vatican City are city-states, and thus do not contain any distinct capital city as a whole. However, in Singapore's case, the main judiciary and legislative offices are located in the Downtown Core. Similarly, while Victoria was the capital of colonial Hong Kong, the heart of old Victoria, now known as Central, serves as the seat of government offices today. Vatican City, however, is the religious centre of the Roman Catholic Church and houses the offices and departments of Holy See which serves as the government of both the city-state and worldwide Catholic Church. Montenegro: The official capital Podgorica is home to the parliament and the executive, but the seat of the presidency is in the former royal capital of Cetinje. Myanmar(Burma): Naypyidaw was designated the national capital in 2005, the same year it was founded, but most government offices and embassies are still located in Yangon(Rangoon). Nauru: Nauru, a microstate of only 21 square kilometres(8.1 sq mi), has no distinct capital city, but has a capital district instead. Philippines: National capital: Presidential Decree No. 940, issued on 24 June 1976, designates the whole of National Capital Region(NCR) or Metro Manila as the seat of government, with the City of Manila as the country's capital. Some national government institutions and agencies are located within the Manila capital city, while others are scattered on other parts of the metropolitan area. The presidential palace(Malacañang Palace, serving as the seat of the President of the Philippines) and the Supreme Court are located within the capital city while the two houses of Congress are located outside the capital Manila but within the metropolis of the same name. Cavite: Imus is designated as the provincial capital, while government offices are in Trece Martires. Portugal: National capital: the Portuguese constitution has no reference to a capital. Although Lisbon is home to the Parliament, the President's and the Prime Minister's official residences, all the Government's departments, all the embassies and the highest courts, no Portuguese official document states that Lisbon is the national capital. Azores: since the establishment of local autonomy in 1976, the Azores has three designated regional capital cities: Ponta Delgada at São Miguel Island(seat of the Autonomous Government); Horta at Faial Island(seat of the Legislative Assembly); and Angra do Heroísmo at Terceira Island(seat of the judiciary and the historical capital of the Azores, in addition to being the seat of the Roman Catholic Diocese of Angra). Sri Lanka: Sri Jayawardenepura Kotte is designated the administrative capital and the location of the parliament, while the former capital, Colombo, is now designated as the "commercial capital". However, many government offices are still located in Colombo. Both cities are in the Colombo District. South Africa: The administrative capital is Pretoria, the legislative capital is Cape Town, and the judicial capital is Bloemfontein. This is the outcome of the compromise that created the Union of South Africa in 1910. Despite Bloemfontein's status as the judicial capital, the country's highest court, the Constitutional Court of South Africa, sits in its largest city, Johannesburg. Switzerland: Bern is the Federal City of Switzerland and functions as de facto capital. However, the Swiss Supreme Court is located in Lausanne which is also the Olympic Capital. Canton of Zürich: Zürich is the de facto capital of the canton, but the cantonal constitution makes no mention of a capital city. Tanzania: Dodoma was designated the national capital in 1996, but some of the government offices and almost all embassies are still located in Dar es Salaam. United States: California: The state executive and legislative branches and most government agencies are based in Sacramento but the California Supreme Court is headquartered in San Francisco with secondary meeting places in Sacramento and Los Angeles. Illinois: Springfield has the seats of the branches of state government and serves as the official state capital. However various Illinois government officials primarily reside in or are primarily active in Chicago.(see: Government of Illinois § Capital city for a further explanation) Louisiana: The state executive and legislative branches and most government agencies are based in Baton Rouge, but the Louisiana Supreme Court is located in New Orleans. New York: The state capital and government are headquartered in Albany, but many officials are mostly active in or live in New York City. Pennsylvania: The state capital is Harrisburg but each one of the state Supreme Court and its two appellate courts holds hearings in the three cities of Harrisburg, Philadelphia, and Pittsburgh. Also, most statewide elected officials and officers who are based in Southeast Pennsylvania(City of Philadelphia, Bucks County, Montgomery County, Delaware County, and Chester County) prefer working mostly in Philadelphia. --Capitals that are not the seat of government-- There are several countries where, for various reasons, the official capital and seat of government are separated: Benin: Porto-Novo is the official capital, but Cotonou is the seat of government. Bolivia: Sucre is the constitutional capital, and the supreme tribunal of justice is located in Sucre, making it the judicial capital. The Palacio Quemado, the national congress and national electoral court are located in La Paz, making it the seat of government. Ivory Coast: Yamoussoukro was designated the national capital in 1983, but most government offices and embassies are still located in Abidjan. Netherlands: Amsterdam is the constitutional national capital even though the Dutch government, the parliament, the supreme court, the Council of State, and the work palace of the King are all located in The Hague, as are all the embassies.(For more details see: Capital of the Netherlands.) Some historical examples of similar arrangements, where the recognized capital was not the official seat of government: Kingdom of England: The traditional capital was the City of London, while Westminster, outside of the boundaries of the City of London, was the seat of government. They are both today part of the urban core of Greater London. Kingdom of France: The traditional capital was Paris, though from 1682 to 1789 the seat of government was at the Palace of Versailles, located in a rural area southwest of Paris. --Disputed capitals-- Cyprus and Northern Cyprus: Nicosia, "the last divided capital", is divided in two by the United Nations Buffer Zone in Cyprus(Green Line). Both the Republic of Cyprus, which has de facto control of the south, and the largely unrecognized Turkish Republic of Northern Cyprus, which has de facto control of North Nicosia, claim the entire city as their capital. Israel and Palestine: Both the Government of Israel and the Palestinian Authority claim Jerusalem as their capital. Jerusalem serves as Israel's capital, with the presidential residence, government offices, supreme court and parliament(Knesset) located there, while the Palestinian Authority has no de facto or de jure control over any of Jerusalem. Many countries, with the notable exception of the United States, which recognizes Jerusalem as the capital of Israel, take the position that the final status of Jerusalem is unsettled pending future negotiations. Most countries maintain their diplomatic missions to Israel in Tel Aviv, while diplomatic missions to Palestine are in various places such as Ramallah, Gaza City, Cairo and Damascus. -Capital as symbol- With the rise of the modern nation-state, the capital city has become a symbol for the state and its government, and imbued with political meaning. Unlike medieval capitals, which were declared wherever a monarch held his or her court, the selection, relocation, founding, or capture of a modern capital city is a highly symbolic event. For example: The ruined and almost uninhabited Athens was made capital of newly independent Greece in 1834, four years after the country gained its independence, with the romantic notion of reviving the glory of Ancient Greece. Similarly, following the Cold War and German reunification, Berlin once again became the capital of Germany. Other restored capital cities include Moscow after the October Revolution. A symbolic relocation of a capital city to a geographically or demographically peripheral location may be for either economic or strategic reasons(sometimes known as a forward capital or spearhead capital). Peter the Great moved his government from Moscow to Saint Petersburg to give the Russian Empire a European orientation. The economically significant city of Nafplion became the first capital of Greece, when Athens was an unimportant village. The Ming emperors moved their capital to Beijing from the more central Nanjing to help supervise the border with the Mongols. During the 1857 rebellion, Indian rebels considered Delhi their capital, and Bahadur Shah Zafar was proclaimed emperor, but the ruling British had their capital in Calcutta. In 1877, the British formally held a 'Durbar' in Delhi, proclaiming Queen Victoria as 'Empress of India'. Delhi finally became the colonial capital after the Coronation Durbar of King-Emperor George V in 1911, continuing as independent India's capital from 1947. Other examples include Abuja, Astana, Brasília, Helsinki, Islamabad, Naypyidaw, and Yamoussoukro. The selection or founding of a "neutral" capital city, one unencumbered by regional or political identities, was meant to represent the unity of a new state when Ankara, Bern, Brasília, Canberra, Madrid, Ottawa and Washington became capital cities. Sometimes, the location of a new capital city was chosen to terminate actual or potential squabbling between various entities, such as in the cases of Brasília, Canberra, Ottawa, Washington, Wellington and Managua. The British-built town of New Delhi represented a simultaneous break and continuity with the past, the location of Delhi being where many imperial capitals were built(Indraprastha, Dhillika, and Shahjahanabad) but the actual capital being the new British-built town designed by Edwin Lutyens. Wellington, on the southwestern tip of the North Island of New Zealand, replaced the much more northerly city of Auckland to place the national capital close to the South Island and hence to placate its residents, many of whom had sympathies with separatism. During the American Civil War, tremendous resources were expended to defend Washington, D.C., which bordered on the Confederate States of America(with the Commonwealth of Virginia), from Confederate attack even though the relatively small federal government could easily have been moved elsewhere. Likewise, great resources were expended by the Confederacy in defending the Confederate capital from attack by the Union, in its exposed location of Richmond, Virginia, barely 100 miles(160 km) south of Washington, D.C. Two national capitals refer to another sovereign state. The name of Tallinn, the capital of Estonia, is thought to be derived from Taani linn, originally meaning "Danish Castle" and now "Danish Town" in Estonian, named after the Toompea Castle, which Denmark controlled in 1219–1227, 1238–1332 and in 1340–1346. Port of Spain, the capital of Trinidad and Tobago, was named so in Spanish by the first settlers from Spain in the 16th century. See List of national capital city name etymologies for more. -Capitals in military strategy- The capital city is usually but not always a primary target in a war, as capturing it usually guarantees capture of much of the enemy government, victory for the attacking forces, or at the very least demoralization for the defeated forces. In ancient China, where governments were massive centralized bureaucracies with little flexibility on the provincial level, a dynasty could easily be toppled with the fall of its capital. In the Three Kingdoms period, both Shu and Wu fell when their respective capitals of Chengdu and Jianye fell. The Ming dynasty relocated its capital from Nanjing to Beijing, where they could more effectively control the generals and troops guarding the borders from Mongols and Manchus. The Ming was destroyed when Li Zicheng took their seat of power, and this pattern repeats itself in Chinese history, until the fall of the traditional Confucian monarchy in the 20th century. After the Qing dynasty's collapse, decentralization of authority and improved transportation and communication technologies allowed both the Chinese Nationalists and Chinese Communists to rapidly relocate capitals and keep their leadership structures intact during the great crisis of Japanese invasion. National capitals were arguably less important as military objectives in other parts of the world, including the West, because of socioeconomic trends toward localized authority, a strategic modus operandi especially popular after the development of feudalism and reaffirmed by the development of democratic and capitalistic philosophies. In 1204, after the Latin Crusaders captured the Byzantine capital, Constantinople, Byzantine forces were able to regroup in several provinces; provincial noblemen managed to reconquer the capital after 60 years and preserve the empire for another 200 years after that. The British forces sacked various American capitals repeatedly during the Revolutionary War and War of 1812, but American forces could still carry on fighting from the countryside, where they enjoyed support from local governments and the traditionally independent civilian frontiersmen. Exceptions to these generalizations include highly centralized states such as France, whose centralized bureaucracies could effectively coordinate far-flung resources, giving the state a powerful advantage over less coherent rivals, but risking utter ruin if the capital were taken. A metropolis() is a large city or conurbation which is a significant economic, political, and cultural area for a country or region, and an important hub for regional or international connections, commerce, and communications. A big city belonging to a larger urban agglomeration, but which is not the core of that agglomeration, is not generally considered a metropolis but a part of it. The plural of the word is metropolises, although the Latin plural is metropoles, from the Greek metropoleis(μητρoπόλεις). For urban areas outside metropolitan areas that generate a similar attraction on a smaller scale for their region, the concept of the regiopolis("regio" for short) was introduced by urban and regional planning researchers in Germany in 2006. -Etymology- Metropolis(μητρόπολις) is a Greek word,(plural: metropoleis) coming from μήτηρ, mḗtēr meaning "mother" and πόλις, pólis meaning "city" or "town", which is how the Greek colonies of antiquity referred to their original cities, with whom they retained cultic and political-cultural connections. The word was used in post-classical Latin for the chief city of a province, the seat of the government and, in particular, ecclesiastically for the seat or see of a metropolitan bishop to whom suffragan bishops were responsible. This usage equates the province with the diocese or episcopal see. In a colonial context, it is the "mother city" of a colony, that is, the city which sent out settlers. The word has distant roots in the colonial past of Ancient Greece with first usage in Middle English around the 14th century. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation. -Concept- The concept of a "metropolis" as a "mother city" dates back to at least sixth-century Canterbury, where the term was used in a religious context, but the term began to be used to describe a large secular city starting with 16th-century London. London's cultural influence meant that until the 19th century, concepts of the "metropolis" were rarely used to describe other cities, though Edinburgh was also described as a "metropolis." While metropolis can often mean any large city, the metropolis is generally understood as a city which serves as a particular function as opposed to simply being large. Modern ideas of a metropolis have changed as modern city growth has created "polycentric" urban regions, where one city does not necessarily dominate its surroundings but instead is central to an economic region. Instead of a single "metropolis" fulfilling an economic role, large urban areas such as the Tokyo–Osaka corridor or the southern California built up area have been considered as a modern "metropolis" even though the region encompasses multiple cities. -Usage as a mainland area- In France, Portugal, Spain, and the Netherlands, the word metropolis(métropole(Fr.) / metrópole(Port.) / metrópoli(Spa.) / metropool(Dutch)) designates the mainland part of a country situated on or close to the European mainland; in the case of France, this means France without its overseas departments. For Portugal and Spain during the Spanish Empire and Portuguese Empire period, the term was used to designate Portugal or Spain minus its colonies(the Ultramar). In France métropole can also be used to refer to a large urban agglomeration; for example, "La Métropole de Lyon"(the Lyon Metropolis). -By country- The following countries either have a specific legal definition of "metropolis" or have a history of usage of the term(or a similar term). --Asia-- ---India--- The 74th Amendment to the Indian Constitution defines a metropolitan area as an area having a population of 10 Lakh or 1 Million or more, comprised in one or more districts and consisting of two or more Municipalities or Panchayats or other contiguous areas, specified by the Governor by public notification to be a Metropolitan area. As of 2011 Census of India, India has 46 other cities with populations greater than one million. Delhi, Mumbai, Kolkata, Chennai, Bangalore, Hyderabad, Pune, Ahmedabad, Kochi, are among the largest of 23 metropolitan cities in India. ---Japan--- The Japanese legal term to(都) is by designation to be translated as "metropolis". However, existing translations predate the designation. Structured like a prefecture instead of a normal city, there is only one to in Japan, namely Tokyo. As of 2020, Japan has 12 other cities with populations greater than one million. The same Kanji character in Chinese, or in generic Japanese(traditional or non-specific), translates variously—city, municipality, special municipality—all qualify. ---Philippines--- The Philippines has three metropolises as defined by the National Economic and Development Authority. They are Manila, Cebu, and Davao. Greater Manila Area is the contiguous urbanization region or Extended Metropolitan Manila surrounding Metro Manila. This built-up zone includes Metro Manila and the neighboring provinces of Bulacan to the north, Cavite and Laguna to the south, and Rizal to the east. Though sprawl continues to absorb new zones, some urban zones are independent clusters of settlements surrounded by non-urban areas. ---South Korea--- In the South Korea, there are seven special and metropolitan cities at autonomous administrative levels. These are the most populous metropolitan areas in the country. In decreasing order of the population of 2015 census, they are Seoul, Busan, Incheon, Daegu, Daejeon, Gwangju and Ulsan. According to the census of 2015, cities of Changwon and Suwon also qualify for being elevated to the level of metropolitan cities(having population over 1 million), but any future plans to promote them into metropolitan city are unlikely to be accepted because of political concerns about the structure of administrative divisions. There are also some county-level cities with increasing population near 1 million, namely Goyang, Yongin, and Seongnam, but they are also unlikely to be promoted into metropolitan city because they are all satellite cities of Seoul. --Europe-- ---France--- A 2014 law allowed any group of communes to cooperate in a larger administrative division called a métropole. One métropole, Lyon, also has status as a department. France's national statistics institute, Insee, designates 12 of the country's urban areas as metropolitan areas. Paris, Lyon and Marseille are the biggest, the other nine being Toulouse, Lille, Bordeaux, Nice, Nantes, Strasbourg, Rennes, Grenoble and Montpellier. ---Germany--- The largest German city by administrative borders is Berlin, while Rhine-Ruhr is the largest metropolitan area(with more than 10 million people). The importance of a city is measured with three groups of indicators, also called metropolitan functions: The decision making and control function, the innovation and competition function, and the gateway function. These functions are seen as key domains for metropolitan regions in developing their performance. In spatial planning, a metropolis is usually observed within its regional context, thus the focus is mainly set on the metropolitan regions. These regions can be mono central or multi central. Eleven metropolitan regions have been defined due to these indicators: Berlin-Brandenburg, Bremen-Oldenburg, Dresden-Halle-Leipzig, Frankfurt-Rhine-Main, Hamburg, Hannover-Braunschweig-Göttingen-Wolfsburg, Munich, Nuremberg, Rhine-Neckar, Rhine-Ruhr(with Cologne/Bonn), and Stuttgart. ---Italy--- As of January 1, 2015, there are 14 "metropolitan cities" in Italy. Rome, Milan, Naples and other big cores have taken in urban zones from their surrounding areas and merged them into the new entities, which have been home for one out of three Italians. The provinces remained in the parts of the country not belonging to any Città Metropolitana. ---Poland--- The Union of Polish metropolises(Polish: Unia Metropolii Polskich), established in 1990, is an organization of the largest cities in the country. Currently twelve cities are members of the organization, of which 11 have more than a quarter-million inhabitants. The largest metropolitan area in Poland, if ranked solely by the number of inhabitants, is the Katowice metropolitan area with around 3 million inhabitants(5 million inhabitants in the Katowice-Ostrava metropolitan area). The Metropolis GZM is an initiative of recent years attempting to unite the conurbation into one official urban unit. It is followed by Warsaw, with around 1.7 million inhabitants in the city proper and 3.1 million in the Warsaw metropolitan area. Other Polish metropolises are Kraków, Łódź, Wrocław, Poznań, Tricity, Szczecin and Bydgoszcz–Toruń. ---Turkey--- In Turkey the metropolitan cities are described as "büyükşehir". There are 30 metropolitan municipalities in Turkey now. The largest by far is Istanbul, followed by Ankara, İzmir and Bursa. Istanbul, the largest city in Europe in terms of population, has a population of over 15 million. The city has surpassed London and Dubai to become the most visited city in the world, with more than 20 million foreign visitors in 2023. This city, which played an important role in the spread of Christianity, is an important heritage for European culture. ---United Kingdom--- In the United Kingdom, the term the Metropolis was historically used to exclusively refer to London, or the London conurbation. The term is retained by the London police force, the Metropolitan Police Service(the "Met"). The chief officer of the Metropolitan Police is formally known as the Commissioner of Police of the Metropolis. Since 1974 six conurbations in England(outside London) have been known as metropolitan counties, each divided into metropolitan districts. These counties are South Yorkshire(centred on the city of Sheffield), the West Midlands(including Birmingham), West Yorkshire(including Leeds), Merseyside(including Liverpool), Greater Manchester and Tyne & Wear(including Newcastle-upon-Tyne). Greater Glasgow, South Hampshire, Greater Nottingham, Greater Bristol, Belfast metropolitan area, and Greater Leicester are also large conurbations with more than half a million citizens. ---Sweden--- In Sweden, the term metropolis has been used to exclusively refer to Stockholm or Greater Stockholm. --North America-- ---Canada--- Statistics Canada defines a census metropolitan area as one or more adjacent municipalities situated around a major urban core where the urban core has a population of at least 100,000. Canada's six largest metropolises are Toronto, Montreal, Vancouver, Ottawa, Calgary, and Edmonton. ---United States--- In the United States, an incorporated area or group of areas having a population more than 50,000 is required to have a metropolitan planning organization in order to facilitate major infrastructure projects and to ensure financial solvency.

The 2012 FIA Formula One World Championship was the 66th season of FIA Formula One motor racing. It featured the 63rd FIA Formula One World Championship, a motor racing series for Formula One cars, recognised by the Fédération Internationale de l'Automobile(FIA) – the governing body of motorsport – as the highest class of competition for open-wheel racing cars. The championship was contested over twenty rounds, which started in Australia on 18 March and ended in Brazil on 25 November. The 2012 season saw the return of the United States Grand Prix, which was held at the Circuit of the Americas, a purpose-built circuit in Austin, Texas. After being cancelled in 2011 due to civil protests, the Bahrain Grand Prix also returned to the calendar. The early season was tumultuous, with seven different drivers winning the first seven races of the championship; a record for the series. It was not until the European Grand Prix in June that a driver, Ferrari's Fernando Alonso, won his second race of the year, and with it, emerged as a championship contender. Alonso maintained his hold on the championship lead for the next seven races, taking his third win in Germany and finishing on the podium in the United Kingdom, Italy and Singapore. However, costly first-lap retirements in Belgium and Japan allowed his rivals to catch up, and defending World Champion Sebastian Vettel – like Alonso, a two-time title winner – took the lead in the sixteenth race of the season. Vettel, too, encountered difficulties throughout the season; contact with a backmarker left him to finish outside the points in Malaysia, while alternator failures at the European and Italian Grands Prix cost him valuable points and exclusion from qualifying in Abu Dhabi led him to start from the pit lane. Vettel entered the final race of the season with a thirteen-point lead over Alonso. Alonso needed a podium finish to stand any chance of becoming World Drivers' Champion, but in a race of attrition that finished under the safety car, Vettel finished in sixth place, scoring enough points to win his third consecutive championship, becoming just the third driver in the sport's sixty-three-year history to do so. In the World Constructors' Championship, Red Bull Racing secured their third consecutive title when Sebastian Vettel finished second at the United States Grand Prix. In addition to seeing seven different drivers win the first seven races, the 2012 season broke several records. The calendar for the season included twenty races, breaking the previous record of nineteen, which was first set in 2005. Six current or former World Drivers' Champions – Sebastian Vettel, Fernando Alonso, Jenson Button, Lewis Hamilton, Kimi Räikkönen, and Michael Schumacher – started the season, breaking the record of five established in 1970. This was the last season for 7-time world champion, Michael Schumacher as he announced his retirement from Formula One for the second time, after the 2012 Brazilian Grand Prix. -Teams and drivers- The following twelve teams and twenty-five race drivers competed in the 2012 Formula One World Championship. The FIA published a provisional entry list on 30 November 2011, and the grid was finalised on 17 February. All teams competed with tyres supplied by Pirelli. --Free practice drivers-- Eight drivers were entered by teams as third or test drivers during Friday practice sessions: --Team changes-- At the November 2011 meeting of the Formula One Commission in Geneva, several teams were given permission to change their constructor names – the name recognised by the FIA as the entity that effectively owns the team, and to which all results for that team are credited – with final approval from the World Motor Sport Council granted in December of that year: Lotus became known as Caterham, reflecting team principal Tony Fernandes's purchase of Caterham Cars. Renault changed its constructor name to Lotus after Lotus Cars expanded its title sponsorship program to include teams in Formula One and support series GP2 and GP3. Virgin became Marussia, following increased ownership of the team by Russian sports car manufacturer Marussia Motors. As a result of the name changes, Team Lotus and Lotus Renault GP declared that their ongoing dispute over the use of the Lotus name was over after they had reached an "amicable conclusion". Although the exact terms of the settlement were kept confidential, the joint statement detailed the transfer of the rights to the Lotus and Team Lotus names to Group Lotus's ownership. Williams announced that they would be using Renault engines for the 2012 and 2013 seasons, with an option to use Renault engines again in 2014 under the next generation of engine regulations. Renault had previously supplied engines to Williams from 1989 to 1997, when the team won four World Drivers' Championships and five World Constructors' Championships. Following their worst season in their thirty-year history – in which they finished ninth in the World Constructors' Championship with just five points – the team underwent a technical review, employing former McLaren designer Mike Coughlan(having served his suspension for his role in the 2007 Formula One espionage controversy) as Chief Designer, and promoting Jason Somerville to Head of Aerodynamics. Likewise, Marussia(then known as Virgin Racing) underwent a restructuring, splitting with Wirth Research mid-season after a technical review by Marussia Motors and the board of directors. The team also announced a technical partnership with McLaren that granted them access to McLaren's testing facilities as well as the purchase of Wirth Research facilities. In the week before the 2011 Indian Grand Prix, Force India announced that the Sahara Group had purchased a 42.5% stake in the team, valued at US$100 million. The investment gave the Sahara Group and team principal Vijay Mallya an equal stake in the team, with team director Michiel Mol controlling the remaining 15% of the team. Under the terms of the sale, the Sahara Group became Force India's naming-rights sponsor. Mercedes GP also changed the name of their team, announcing that they were to become known as Mercedes AMG. The new name originates from AMG, Mercedes-Benz's performance and luxury road car brand. HRT team principal Colin Kolles formally left his position, with the team citing the relocation of their headquarters to Spain as the reason for the separation. Former Minardi driver Luis Pérez-Sala took Kolles's place as team principal. In January 2012, the team relocated to a new facility in Valencia before settling at a permanent facility in Caja Mágica, Madrid. Peter Sauber formally stepped down from his position as team principal of Sauber F1 in the week before the Korean Grand Prix, appointing the team's CEO, Monisha Kaltenborn as his successor. Kaltenborn's appointment made her the first female team principal in the sport's sixty-three-year history. --Driver changes-- The 2012 season saw several driver changes. Lotus chose not to take up an option on Vitaly Petrov's contract, and did not offer Bruno Senna a new contract. Petrov and Senna were replaced by 2007 World Drivers' Champion Kimi Räikkönen – returning to the sport after two seasons competing in the World Rally Championship – and reigning GP2 Series champion Romain Grosjean, who also returned to the sport after a two-year absence. Petrov later replaced Jarno Trulli at Caterham; Trulli's replacement meant that the opening race of the season would be the first race since the 1973 German Grand Prix to take place without an Italian driver on the grid. Senna joined Williams, the team having previously attempted to secure Räikkönen for the season. Senna replaced Rubens Barrichello, who left Formula One after a record-breaking nineteen seasons. He later moved to IndyCar for the 2012 season, joining KV Racing Technology. Like Räikkönen and Grosjean, Nico Hülkenberg also returned to Formula One, joining Force India alongside Paul di Resta. Adrian Sutil left the team, having spent six years with both Force India and its previous incarnations, Spyker and Midland. He initially sought a drive with Williams, before negotiations collapsed in December 2011. Sutil was later the subject of criminal action, charged with grievous bodily harm after allegedly assaulting a senior Renault team member with a glass in a Shanghai nightclub following the 2011 Chinese Grand Prix. Sutil was found guilty, and was sentenced to an eighteen-month suspended jail sentence and ordered to pay a €200,000 fine. Despite this, Sutil rejoined Force India for the 2013 season. Scuderia Toro Rosso did not retain Jaime Alguersuari or Sébastien Buemi, instead choosing to replace them with Daniel Ricciardo and 2011 Formula Renault 3.5 Series runner-up Jean-Éric Vergne. Ricciardo had previously served as the team's test and reserve driver before being placed at HRT for the 2011 British Grand Prix, while Vergne had completed a limited testing schedule for the team in the second half of the 2011 season. Sébastien Buemi became Red Bull Racing's testing and reserve driver contested the 24 Hours of Le Mans with Toyota, driving a TS030 Hybrid. Alguersuari was offered a seat at HRT, but turned it down and instead joined tyre supplier Pirelli as their test driver, developing tyre compounds for use in racing alongside former Virgin Racing driver Lucas di Grassi. Pedro de la Rosa and Narain Karthikeyan returned to Formula One with HRT. De la Rosa had been without a full-time drive since the 2010 Italian Grand Prix, having spent the majority of the 2011 season as a test driver for McLaren and making one appearance racing for Sauber; Karthikeyan was dropped by the team before the 2011 British Grand Prix in favour of Ricciardo. He, too, made a one-race appearance at the Indian Grand Prix, before leaving the team until the 2012 season began. Vitantonio Liuzzi, who drove for HRT in 2011, joined the Indian i1 Super Series. The series was later postponed until 2013, but Liuzzi was unable to retain his seat with the team. At the launch of the HRT F112 in March, Liuzzi was confirmed as one of the team's testing and reserve drivers alongside both former GP2 Series driver Dani Clos and Ma Qinghua, the first ever Chinese driver to step into a Formula 1 car. Jérôme d'Ambrosio left Marussia(then known as Virgin Racing) after the 2011 Brazilian Grand Prix. He later joined Lotus F1 as their third driver. Charles Pic – who placed fourth in the 2011 GP2 Series driving for Addax – joined Marussia, replacing d'Ambrosio. ---Mid-season changes--- The season only saw one driver change, which was brought about when Lotus driver Romain Grosjean was found by race stewards to be responsible for causing a multi-car pile-up at the start of the Belgian Grand Prix. He was given a one-race ban and a €50,000 fine for his role in the collision, forcing him to miss the Italian Grand Prix. He was replaced by the team's testing and reserve driver, Jérôme d'Ambrosio. Grosjean returned to the team for the next round in Singapore. -Calendar- --Calendar changes-- ---New and returning races--- After the 2011 Bahrain Grand Prix was cancelled, the race was reinstated for the 2012 season with a provisional date in October. The final version of the calendar brought the race forward to April. The German Grand Prix returned to Hockenheim after the 2011 German Grand Prix was held at the Nürburgring, in line with the event's policy of alternating between venues. In May 2010, it was announced that Austin, Texas would host the return of the United States Grand Prix, the first since Indianapolis in 2007. Known as the Circuit of the Americas, the venue will be a brand-new, purpose-built permanent circuit designed by event promoter Tavo Hellmund and 1993 Grand Prix Motorcycle World Champion Kevin Schwantz with the assistance of German architect and circuit designer Hermann Tilke. In November 2011, Bernie Ecclestone expressed "minor" doubt over the race going ahead after what he described as "disagreements inside the [management] company" and gave the circuit owners and race organisers a deadline of 7 December – coinciding with the meeting of the FIA World Motor Sport Council and the release of the final 2012 calendar – to sort out their differences or else risk losing the event entirely. The final calendar included the race, with Ecclestone confirming that a new arrangement had been made, and that the event organisers had paid their circuit sanctioning fees for 2012. The race was originally scheduled to be held in June, but was moved back to become the penultimate event of the season in response to concerns over the heat of the Texas summer and its effects on teams, drivers and spectators, and the failure of race organisers to meet a key deadline for the race sanctioning fees. ---Failed races--- The Turkish Grand Prix was firstly included in the provisional calendar, but then it was removed from the calendar after Formula One Management and the event organisers could not agree on a renewed contract. In August 2011, organisers of the race revealed that they were negotiating with Bernie Ecclestone to resume their place on the calendar. However, the race was removed from the calendar later that month. It would eventually return in 2020 due to the COVID-19 pandemic. -Changes- --Rule changes-- ---Technical regulations--- The 2011 season saw teams running "off-throttle blown diffusers", which created downforce by forcing fuel through the engine to produce exhaust gases and directing it over the diffuser when the driver was not applying the throttle. This concept was originally banned in incremental phases, with increasingly restrictive rules on what teams could and could not do, with a full ban to be applied from the 2011 British Grand Prix onwards. However, the incremental ban was controversial, with several teams applying for and receiving permission to circumvent the total ban. After discussion between the FIA and engine manufacturers, the original regulations were restored, with the full ban delayed until 2012. The regulations in 2012 governed the design of the exhaust with the teams agreeing to strict constraints on the position of the exhaust tailpipe. This resulted in the exhaust exiting the bodywork much higher up than in 2011, and no longer in the vicinity of the diffuser. Several teams, including Williams and Mercedes used the Young Driver Tests in Abu Dhabi as an opportunity to test parts for the 2012 season in the face of the ban. In October 2011, a clarification to the amended rules was issued, effectively banning "exotic" engine maps; in November, further amendments were introduced, completely banning the practice of blowing exhaust gasses over parts of the car to improve downforce, following a bid by several teams to allow it under certain conditions. Further amendments were made in February 2012 when Mercedes alerted the FIA to a loophole in the regulations that would allow teams to continue using a partially blown diffuser. The FIA responded by re-writing the software governing the engine's Electronic Control Unit to close the loophole. At the German Grand Prix in July, Red Bull Racing were referred to race stewards after FIA Technical Delegate Jo Bauer noted that their engine maps had the potential to violate the technical regulations. Red Bull stood accused of manipulating the relationship between the torque produced by the Red Bull RB8 and the degree to which the throttle was open – particularly in medium-speed corners – thereby allowing more air to pass through the exhaust and over the diffuser, generating more downforce. Red Bull were cleared of wrongdoing, as, in the stewards' words, they had not technically broken any rules, but the FIA announced plans to rewrite the regulations governing throttle mapping so as to outlaw the practice entirely ahead of the Hungarian Grand Prix one week later. The rule changes required teams to submit an engine map used during one of the first four races of the season, which became known as the "reference map". Any subsequent changes to the throttle map would require the approval of the FIA, provided that the torque output above 6,000 rpm was within two percent of the output specified on the reference map. Further changes would be allowed at races with "exceptional atmospheric conditions", as designated by the FIA. In January 2012, the FIA banned the use of "reactive ride-height". The system, first proposed by Lotus in 2010(but not applied until 2012), used hydraulic cylinders located in the brake calipers and suspension push-rods to make minute adjustments to the ride height of the car, thereby keeping the ride height at an optimal level throughout the race and providing stability during braking. The FIA initially approved the device as being legal, and several teams, including Ferrari and Williams, submitted plans to the FIA for their own versions of the device before it was banned one week later. The FIA later confirmed that the reactive ride-height systems violated Article 3.15 of the technical regulations, which states that "any aerodynamic effect created by the suspension should be incidental to its primary function" and "any device that influences the car's aerodynamics must remain immobile in relation to the sprung part of the car" and further noted that the system's primary purpose was achieving aerodynamic gains as opposed to providing stability under braking, and that the use of reactive ride-heights could also be challenged under Article 10.2 of the technical regulations, which govern suspension systems. Technical regulations for 2012 include the reprofiling of the car's nose. The pre-2012 regulations allowed the nose to be as high as 62.5 centimetres(24.6 in) above ground, but the revisions to the sporting code lowered the maximum allowable height to 55 centimetres(22 in) 150mm ahead of the front bulkhead. This resulted in cars being launched with a "platypus" nose, as teams designed cars with a visible change in height along the nose assembly of the car. Mercedes AMG team principal Ross Brawn explained the distinctive nose shape as having come about from "several teams" wanting to use their 2011 chassis as the basis for their 2012 cars. Drivers were no longer permitted to have a "joker" gearbox change. Prior to 2012, drivers were entitled to change their gearboxes once over the course of the season without incurring a five-place grid penalty. This system was abandoned in 2012, with drivers only being allowed to change gearboxes once every five races. Starting in 2012, all cars were required to pass their mandatory FIA crash tests before being allowed to take part in pre-season testing. Previously, passing the crash tests was only a requirement prior to the first race of the season. Crash tests for the 2012 season will also be more rigorous than in previous years. At the meeting for the Formula One Commission in Geneva in November 2011, the use of helium in air guns used to change tyres during pit stops was banned. Despite increasing the rotation speed of the air guns by up to 30%, the practice of using helium was deemed to be too expensive to continue for the competitive gains it offered. At the 2012 Abu Dhabi Grand Prix, the FIA banned the use of "trick brake" devices, which used a bi-metallic strip that changed shape when heated by the brakes to open or close off braking ducts and improving braking efficiency under certain conditions. This was deemed to be in breach of Article 11.4 of the Sporting Regulations, which states that the only permissible changes to the braking system while a car is moving must be directly controlled by the driver. ---Sporting regulations--- After being banned in 2009, in-season testing returned in 2012, with a test held at Mugello on 1 May ahead of the European leg of the 2012 championship. As teams were only permitted to do fifteen days of testing over the course of the season, the pre-season winter testing schedule was cut back to accommodate the Mugello test. At the September 2011 meeting of the FIA World Motor Sport Council, representatives of the member organisations voted to amend the rules for double-waved yellow flags in all FIA-sanctioned championships. The amendment means that double-waved flags will be shown when a track marshal is working on or beside the circuit. Tyre supplier Pirelli revised their tyre compounds for the 2012 season in an effort to encourage teams to use each of the compounds supplied for individual races. Pirelli predicted that the changes would translate into 0.7 seconds' difference per lap between the harder and softer compounds, down from 1.5 seconds per lap in 2011. According to Pirelli, the hardest tyre compound available is just 31% harder than the softest compound on offer; by comparison, the hardest tyres used in 2011 were 70% harder than the softest. Faced with several constructors applying for name changes, teams requested a clearer definition of what constitutes a "constructor". Under the rules set out in the Sixth Concorde Agreement, several teams have been forced to compete under names that do not necessarily reflect their ownership—such as Sauber competing as "BMW Sauber" in 2010, despite BMW withdrawing from the sport at the end of the 2009 season—in order to preserve their status as a current constructor and their claim to a share of the television rights paid to teams that placed in the top ten in the final World Constructors' Championship standings. At the final meeting of the World Motorsports Commission in December 2011, a series of amendments to the sporting regulations were published. Chief among these is the re-introduction of a rule that will allow all lapped traffic under the safety car(which remained the Mercedes-Benz SLS AMG introduced in 2010) to be released from the queue before the car returns to pit lane, allowing the drivers to unlap themselves and to ensure a clean restart. Drivers were not permitted to leave the confines of the circuit without a justifiable reason, following a spate of incidents in 2011 when drivers were sighted using access roads around the circuit to shorten their reconnaissance and in-laps in order to preserve their fuel and tyres. Similarly, drivers will not be allowed to return to the normal racing line should they choose a defensive line going into a corner. Races were run to a maximum four-hour time limit to prevent the indefinite suspension of a race. This will stop the theoretical possibility of a race lasting more than eight hours. This rule was introduced in response to the rain-interrupted 2011 Canadian Grand Prix, which set a record for the longest race in Formula One history, at four hours, four minutes and thirty-nine seconds. Any driver in the pit lane when a race is suspended was permitted to return to the circuit and take up the position on the grid that they were running in at the time of the suspension. At the 2012 British Grand Prix in July, the FIA disabled the use of the Drag Reduction System(DRS) during a race while yellow flags were being shown in the same sector as the DRS zone. The move followed an incident at the European Grand Prix in which Michael Schumacher was observed to activate his DRS while yellow flags were being shown. --Other changes-- In July 2011, a joint broadcasting deal for Formula One in the United Kingdom was announced between Sky Sports and the BBC. The announcement was controversial, being met with highly negative reactions from fans and observers as it had previously been believed that the terms of the Concorde Agreement prevented Formula One from being broadcast exclusively on pay-per-view, but the Agreement did not prevent a shared broadcast such as the proposal made by Sky Sports and the BBC. The controversial nature of the broadcast deal led to the Culture, Media and Sport Committee of the House of Commons calling Bernie Ecclestone and "senior BBC figures" including director-general Mark Thompson to answer questions over the details of the broadcasting arrangement. In December 2011, Red Bull Racing and Scuderia Ferrari exited FOTA, the Formula One Teams Association, following prolonged debate over the implementation of the controversial Resource Restriction Agreement, though Red Bull team principal Christian Horner reaffirmed his team's commitment to cost-cutting measures and highlighting the team's concerns over certain loopholes in the Resource Restriction Agreement that they felt teams and manufacturers would willingly exploit. One week later, Sauber also left the organisation, though the Swiss team did not publicly give a reason for ending their membership. In February 2012, Red Bull Racing's sister team Scuderia Toro Rosso was also reported as having left the organisation since the first schism in December. -Race summaries- --Pre-season testing – Jerez de la Frontera and Barcelona-- The 2012 season was preceded by three test sessions; one at Jerez de la Frontera and two in Barcelona. These sessions gave the teams and drivers the opportunity to familiarise themselves with their cars, though the teams downplayed the accuracy of testing times as being representative of the running order for the season. At the second test in Barcelona, Lotus F1 discovered a critical fault in the build of their chassis that forced them to miss four days of running, while both HRT and Marussia were unable to complete any mileage with their 2012 cars after both the HRT F112 and Marussia MR01 failed their crash tests, though both teams were able to complete shakedowns of their cars. --Round 1 – Australia-- The season began in Australia. Jenson Button took an early lead from pole-sitter Lewis Hamilton and the Red Bull cars while the rest of the field was bottle-necked by contact in the first corner. Button remained unchallenged throughout, even after a mid-race safety car to retrieve the stricken Caterham of Vitaly Petrov. Button went on to take his third victory at the Melbourne circuit, ahead of Sebastian Vettel, who profited from the safety car to pass Hamilton. McLaren team principal Martin Whitmarsh later admitted that Button was "more than marginal" on fuel after the team made a mistake in calculating their fuel loads for the race, forcing Button to use a "severe fuel-saving mode" from the eighth lap of the race. Hamilton came under threat from Mark Webber in the late stages of the race, but held on to secure third place. Webber finished fourth – his best result in his home Grand Prix – while Fernando Alonso finished fifth, having endured pressure from Pastor Maldonado for the last half of the race. Maldonado's race ended when he crossed onto the astroturf on the final lap and spun into the wall. Kimi Räikkönen finished seventh after a poor qualifying session saw him start the race seventeenth, taking advantage of a chaotic final lap to make up two places, while Felipe Massa and Bruno Senna both retired after a bizarre collision that saw their cars tangled up in one another. HRT failed to qualify for the race for the second consecutive season after drivers Pedro de la Rosa and Narain Karthikeyan failed to set a lap time within 107% of the fastest qualifying time. --Round 2 – Malaysia-- McLaren locked out the front row of the grid for the second race in succession, with Lewis Hamilton once again on pole. Both HRT cars qualified for the race, but filled out the final row of the grid almost two seconds behind Marussia's Charles Pic in twenty-second position. In the race, Hamilton made a better start than Jenson Button, but his lead was short-lived; heavy rain interrupted the race, forcing the suspension of the Grand Prix. When the race restarted an hour later, Button was involved in contact with Narain Karthikeyan that forced him to make an unscheduled stop for a new front wing, while Hamilton had a slow pit stop and was held in the lane while other cars passed. Fernando Alonso inherited the lead, with Sauber's Sergio Pérez a surprise second, having made an early stop for extreme wet weather tyres and then taking advantage of a rush to the pit lane to position himself in third at the restart. As the race wore on, Pérez began to quickly catch Alonso on a drying track. Daniel Ricciardo was the first driver to pit for dry-weather tyres on lap 38, triggering another round of stops. Sauber and Pérez initially looked as if they had left their stop too late when Pérez emerged from the pits five seconds behind Alonso, but he began catching the two-time World Champion at the same rate as he had before. Pérez closed to within half a second with seven laps to go, but ran wide at turn 14 and lost five seconds, later admitting that it was his mistake. He was unable to close the gap, and Alonso went on to win the race by two seconds, the win giving him a five-point lead in the championship. Pérez was second, taking his first podium and Sauber's best ever result as an independent team. Hamilton finished third ahead of Mark Webber and Kimi Räikkönen, while Button had to settle for fourteenth. Bruno Senna finished in sixth, scoring more points in a single race than his team scored in 2011. Sebastian Vettel finished outside the points after making contact with Karthikeyan and developing a puncture. --Round 3 – China-- The championship resumed three weeks later in China, with the lead-in period to the race marked by Lotus F1 protesting the legality of Mercedes's rear wing design. The FIA rejected the protest, and with Mercedes allowed to continue racing with their car unchanged, Nico Rosberg took his – and the team's – first pole position since their return to Formula One in 2010, while a penalty to Lewis Hamilton for a gearbox change promoted Michael Schumacher to second on the grid. Schumacher would ultimately retire from the race after the first round of stops when it was discovered that one of his wheels had not been attached properly. Rosberg took an early lead in the race, and while his attempt to complete the race with only two pit stops came under threat from second-placed Jenson Button, a mistake by Button's pit crew during his final stop handed Rosberg a nineteen-second advantage over Kimi Räikkönen. Räikkönen was attempting a similar two-stop strategy, but his tyres wore out seven laps from the end of the race, and he lost eleven positions in a single lap. This forced Rosberg to drive conservatively to preserve his tyres while Button recovered from his disastrous pit stop to pass Sebastian Vettel for second. Button was held up by the incumbent World Champion long enough for Rosberg to preserve his tyres, and he became the 103rd person to win a Grand Prix. The result was also Mercedes's first win as a constructor since Juan Manuel Fangio won the 1955 Italian Grand Prix. Button was second, with Hamilton scoring his third consecutive third place, giving him a two-point championship lead over Button; Fernando Alonso, who had been leading the championship before the race, finished ninth. After two retirements in the opening rounds of the championship, Romain Grosjean scored his first points in Formula One by finishing sixth. --Round 4 – Bahrain-- In the face of ongoing media speculation and public pressure to cancel the race due to ongoing political instability in Bahrain, the FIA released a statement at the Chinese Grand Prix confirming that the Bahrain Grand Prix would go ahead as planned. The week preceding the Grand Prix saw a renewed wave of protests against the government's attempts use the race to "tell the outside world that the whole thing is back to normal", while human rights organisations including Amnesty International criticised the decision to hold the race amid the violent crackdowns. Three days before the race, a group of Force India mechanics travelling in an unmarked hire car were involved in a petrol bombing incident at an impromptu roadblock and were briefly exposed to tear gas fired by security forces. There were no injuries or damage, but two of the mechanics involved chose to leave the country. The team later announced their intentions to race despite the incident. Sebastian Vettel qualified on pole, his first since the 2011 Brazilian Grand Prix. Heikki Kovalainen qualified sixteenth, the second time Caterham(and its predecessor, Team Lotus) advanced beyond the first qualifying period in dry conditions. Vettel went on to win the race – becoming the fourth winner in as many races – after spending much of the race defending against Kimi Räikkönen. Having started eleventh, Räikkönen used an extra set of soft tyres to move up through the field. His team-mate, Romain Grosjean, finished third. Grosjean had initially shown the pace to challenge Vettel's lead, but unlike Räikkönen, he did not have an extra set of fresh tyres, and lost touch with the reigning World Champion after the first set of stops. Lewis Hamilton finished eighth, once again hampered by slow pit stops. He was later involved in an altercation with Nico Rosberg that saw Rosberg referred to the stewards for forcing Hamilton beyond the boundary of the circuit while defending his position, but he escaped without penalty. Hamilton went on to finish eighth, while team-mate Jenson Button was forced to retire two laps from the end of the race after reporting an unusual vibration from the differential. Daniel Ricciardo was involved in early contact that saw the Australian driver slide down the order from sixth at the start to fifteenth by the end of the race, having spent most of the Grand Prix caught behind Vitaly Petrov. Vettel's win gave him a four-point lead in the championship over Hamilton, while Mark Webber's fourth consecutive fourth place secured third overall. Red Bull Racing took the lead from McLaren in the World Constructors' Championship, while Lotus's double podium moved them into third overall. The decision to hold the race despite the ongoing protests made it one of the most controversial Grands Prix in the sport's sixty-year history. --Mid-season test – Mugello-- Starting on 1 May, the teams conducted a three-day test at the Mugello Circuit in Italy ahead of the Spanish Grand Prix. The test gave teams the opportunity to assess major aerodynamic upgrades before racing them. HRT elected not to take part in the test, instead choosing to concentrate on establishing themselves at their new headquarters in Madrid. Both Lotus's trackside operations director Alan Permane and Red Bull Racing driver Mark Webber questioned the value of testing at the Mugello circuit as the characteristics of the circuit were unlike any of the circuits the championship was due to visit after the test, while Caterham driver Vitaly Petrov was critical of the choice of Mugello as a testing venue as he felt it was not safe enough for Formula One. Petrov's comments came shortly after Fernando Alonso crashed on the final morning of the test. Red Bull Racing and Lotus team principals Christian Horner and Éric Boullier were also critical of the test as they felt that the costs of conducting in-season testing outweighed any benefits, with Horner stating his opposition to continuing mid-season testing in the future. --Round 5 – Spain-- Following criticism over the sensitivity of their tyre compounds, tyre supplier Pirelli announced changes to their tyre allocation for the Spanish Grand Prix, making pit strategy the focal point of the Grand Prix. Pirelli would later diagnose the problems with the tyre compounds as originating from developing them on a testing chassis that was two years out-of-date at the time. Lewis Hamilton took his third pole of the season, edging out Williams driver Pastor Maldonado by half a second, while Maldonado's team-mate Bruno Senna was eliminated early when he spun. Hamilton was later excluded from the qualifying results after his car did not have enough fuel to return to the pits for scrutineering, promoting Maldonado to pole position and moving Hamilton to the back of the grid. Fernando Alonso took the lead of the race at the first corner, but Maldonado reclaimed it during the second round of pit stops, when his team forced Ferrari to pit early while Alonso was held up by the Marussia of Charles Pic. Maldonado maintained a lead of seven seconds over Alonso, but a mistake by his crew during the third pit stop cost him time and left him vulnerable to the Ferrari driver in the final stint of the race.

A treaty is a formal, legally binding written agreement between sovereign states and/or international organizations that is governed by international law. A treaty may also be known as an international agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms; however, only documents that are legally binding on the parties are considered treaties under international law. Treaties may be bilateral(between two countries) or multilateral(involving more than two countries). Treaties are among the earliest manifestations of international relations; the first known example is a border agreement between the Sumerian city-states of Lagash and Umma around 3100 BC. International agreements were used in some form by most major civilizations and became increasingly common and more sophisticated during the early modern era. The early 19th century saw developments in diplomacy, foreign policy, and international law reflected by the widespread use of treaties. The 1969 Vienna Convention on the Law of Treaties(VCLT) codified these practices and established rules and guidelines for creating, amending, interpreting, and terminating treaties, and for resolving disputes and alleged breaches. Treaties are roughly analogous to contracts in that they establish the rights and binding obligations of the parties. They vary in their obligations(the extent to which states are bound to the rules), precision(the extent to which the rules are unambiguous), and delegation(the extent to which third parties have authority to interpret, apply and make rules). Treaties can take many forms and govern a wide range of subject matters, such as security, trade, environment, and human rights; they may also be used to establish international institutions, such as the International Criminal Court and the United Nations, for which they often provide a governing framework. Treaties serve as primary sources of international law and have codified or established most international legal principles since the early 20th century. In contrast with other sources of international law, such as customary international law, treaties are only binding on the parties that have signed and ratified them. Notwithstanding the VCLT and customary international law, treaties are not required to follow any standard form, and differ widely in substance and complexity. Nevertheless, all valid treaties must comply with the legal principle of pacta sunt servanda(Latin: "agreements must be kept"), under which parties are committed to perform their duties and honor their agreements in good faith. A treaty may also be invalidated, and thus rendered unenforceable, if it violates a preemptory norm(jus cogens), such as permitting a war of aggression or crimes against humanity. -Modern usage and form- A treaty is an official, express written agreement that states use to legally bind themselves. It is also the objective outcome of a ceremonial occasion that acknowledges the parties and their defined relationships. There is no prerequisite of academic accreditation or cross-professional contextual knowledge required to publish a treaty. However, since the late 19th century, most treaties have followed a fairly consistent format. A treaty typically begins with a preamble describing the "High Contracting Parties" and their shared objectives in executing the treaty, as well as summarizing any underlying events(such as the aftermath of a war in the case of a peace treaty). Modern preambles are sometimes structured as a single very long sentence formatted into multiple paragraphs for readability, in which each of the paragraphs begins with a gerund(desiring, recognizing, having, etc.). The High Contracting Parties—referred to as either the official title of the head of state(but not including the personal name), e.g. His Majesty The King of X or His Excellency The President of Y, or alternatively in the form of " Government of Z"—are enumerated, along with the full names and titles of their plenipotentiary representatives; a boilerplate clause describes how each party's representatives have communicated(or exchanged) their "full powers"(i.e., the official documents appointing them to act on behalf of their respective high contracting party) and found them in good or proper form. However, under the Vienna Convention on the Law of Treaties if the representative is the head of state, head of government or minister of foreign affairs, no special document is needed, as holding such high office is sufficient. The end of the preamble and the start of the actual agreement is often signaled by the words "have agreed as follows". After the preamble comes numbered articles, which contain the substance of the parties' actual agreement. Each article heading usually encompasses a paragraph. A long treaty may further group articles under chapter headings. Modern treaties, regardless of subject matter, usually contain articles governing where the final authentic copies of the treaty will be deposited and how any subsequent disputes as to their interpretation will be peacefully resolved. The end of a treaty, the eschatocol(or closing protocol), is often signaled by language such as "in witness whereof" or "in faith whereof", followed by the words "DONE at", then the site(s) of the treaty's execution and the date(s) of its execution. The date is typically written in its most formal, non-numerical form; for example, the Charter of the United Nations reads "DONE at the city of San Francisco the twenty-sixth day of June, one thousand nine hundred and forty-five". If applicable, a treaty will note that it is executed in multiple copies in different languages, with a stipulation that the versions in different languages are equally authentic. The signatures of the parties' representatives follow at the very end. When the text of a treaty is later reprinted, such as in a collection of treaties currently in effect, an editor will often append the dates on which the respective parties ratified the treaty and on which it came into effect for each party. --Bilateral and multilateral treaties-- Bilateral treaties are concluded between two states or entities. It is possible for a bilateral treaty to have more than two parties; for example, each of the bilateral treaties between Switzerland and the European Union(EU) has seventeen parties: The parties are divided into two groups, the Swiss("on the one part") and the EU and its member states("on the other part"). The treaty establishes rights and obligations between the Swiss and the EU and the member states severally—it does not establish any rights and obligations amongst the EU and its member states. A multilateral treaty is concluded among several countries, establishing rights and obligations between each party and every other party. Multilateral treaties may be regional or may involve states across the world. Treaties of "mutual guarantee" are international compacts, e.g., the Treaty of Locarno which guarantees each signatory against attack from another. --Role of the United Nations-- The United Nations has extensive power to convene states to enact large-scale multilateral treaties and has experience doing so. Under the United Nations Charter, which is itself a treaty, treaties must be registered with the UN to be invoked before it, or enforced in its judiciary organ, the International Court of Justice. This was done to prevent the practice of secret treaties, which proliferated in the 19th and 20th centuries and often precipitated or exacerbated conflict. Article 103 of the Charter also states that its members' obligations under the Charter outweigh any competing obligations under other treaties. After their adoption, treaties, as well as their amendments, must follow the official legal procedures of the United Nations, as applied by the Office of Legal Affairs, including signature, ratification and entry into force. In function and effectiveness, the UN has been compared to the United States federal government under the Articles of Confederation. -Adding and amending treaty obligations- --Reservations-- Reservations are essentially caveats to a state's acceptance of a treaty. Reservations are unilateral statements purporting to exclude or to modify the legal obligation and its effects on the reserving state. These must be included at the time of signing or ratification, i.e., "a party cannot add a reservation after it has already joined a treaty". Article 19 of the Vienna Convention on the law of Treaties in 1969. Originally, international law was unaccepting of treaty reservations, rejecting them unless all parties to the treaty accepted the same reservations. However, in the interest of encouraging the largest number of states to join treaties, a more permissive rule regarding reservations has emerged. While some treaties still expressly forbid any reservations, they are now generally permitted to the extent that they are not inconsistent with the goals and purposes of the treaty. When a state limits its treaty obligations through reservations, other states party to that treaty have the option to accept those reservations, object to them, or object and oppose them. If the state accepts them(or fails to act at all), both the reserving state and the accepting state are relieved of the reserved legal obligation as concerns their legal obligations to each other(accepting the reservation does not change the accepting state's legal obligations as concerns other parties to the treaty). If the state opposes, the parts of the treaty affected by the reservation drop out completely and no longer create any legal obligations on the reserving and accepting state, again only as concerns each other. Finally, if the state objects and opposes, there are no legal obligations under that treaty between those two state parties whatsoever. The objecting and opposing state essentially refuses to acknowledge the reserving state is a party to the treaty at all. --Amendments-- There are three ways an existing treaty can be amended. First, a formal amendment requires State parties to the treaty to go through the ratification process all over again. The re-negotiation of treaty provisions can be long and protracted, and often some parties to the original treaty will not become parties to the amended treaty. When determining the legal obligations of states, one party to the original treaty and one party to the amended treaty, the states will only be bound by the terms they both agreed upon. Treaties can also be amended informally by the treaty executive council when the changes are only procedural, technical change in customary international law can also amend a treaty, where state behavior evinces a new interpretation of the legal obligations under the treaty. Minor corrections to a treaty may be adopted by a procès-verbal; but a procès-verbal is generally reserved for changes to rectify obvious errors in the text adopted, i.e., where the text adopted does not correctly reflect the intention of the parties adopting it. --Protocols-- In international law and international relations, a protocol is generally a treaty or international agreement that supplements a previous treaty or international agreement. A protocol can amend the previous treaty or add additional provisions. Parties to the earlier agreement are not required to adopt the protocol, and this is sometimes made explicit, especially where many parties to the first agreement do not support the protocol. A notable example is the United Nations Framework Convention on Climate Change(UNFCCC), which established a general framework for the development of binding greenhouse gas emission limits, followed by the Kyoto Protocol contained the specific provisions and regulations later agreed upon. -Execution and implementation- Treaties may be seen as "self-executing", in that merely becoming a party puts the treaty and all its obligations in action. Other treaties may be non-self-executing and require "implementing legislation"—a change in the domestic law of a state party that will direct or enable it to fulfill treaty obligations. An example of a treaty requiring such legislation would be one mandating local prosecution by a party for particular crimes. The division between the two is often unclear and subject to disagreements within a government, since a non-self-executing treaty cannot be acted on without the proper change in domestic law; if a treaty requires implementing legislation, a state may default on its obligations due to its legislature failing to pass the necessary domestic laws. --Interpretation-- The language of treaties, like that of any law or contract, must be interpreted when the wording does not seem clear, or it is not immediately apparent how it should be applied in a perhaps unforeseen circumstance. The Vienna Convention states that treaties are to be interpreted "in good faith" according to the "ordinary meaning given to the terms of the treaty in their context and in the light of its object and purpose". International legal experts also often invoke the "principle of maximum effectiveness", which interprets treaty language as having the fullest force and effect possible to establish obligations between the parties. No one party to a treaty can impose its particular interpretation of the treaty upon the other parties. Consent may be implied, however, if the other parties fail to explicitly disavow that initially unilateral interpretation, particularly if that state has acted upon its view of the treaty without complaint. Consent by all parties to the treaty to a particular interpretation has the legal effect of adding another clause to the treaty – this is commonly called an "authentic interpretation". International tribunals and arbiters are often called upon to resolve substantial disputes over treaty interpretations. To establish the meaning in context, these judicial bodies may review the preparatory work from the negotiation and drafting of the treaty as well as the final, signed treaty itself. --Consequences of terminology-- One significant part of treaty-making is that signing a treaty implies a recognition that the other side is a sovereign state and that the agreement being considered is enforceable under international law. Hence, nations can be very careful about terming an agreement to be a treaty. For example, within the United States, agreements between states are compacts and agreements between states and the federal government or between agencies of the government are memoranda of understanding. Another situation can occur when one party wishes to create an obligation under international law, but the other party does not. This factor has been at work with respect to discussions between North Korea and the United States over security guarantees and nuclear proliferation. The definition of the English word "treaty" varies depending on the legal and political context; in some jurisdictions, such as the United States, a treaty is specifically an international agreement that has been ratified, and thus made binding, per the procedures established under domestic law. --Enforcement-- While the Vienna Convention provides a general dispute resolution mechanism, many treaties specify a process outside the convention for arbitrating disputes and alleged breaches. This may by a specially convened panel, by reference to an existing court or panel established for the purpose such as the International Court of Justice, the European Court of Justice or processes such as the Dispute Settlement Understanding of the World Trade Organization. Depending on the treaty, such a process may result in financial penalties or other enforcement action. -Ending treaty obligations- --Withdrawal-- Treaties are not necessarily permanently binding upon the signatory parties. As obligations in international law are traditionally viewed as arising only from the consent of states, many treaties expressly allow a state to withdraw as long as it follows certain procedures of notification("denunciation"). For example, the Single Convention on Narcotic Drugs provides that the treaty will terminate if, as a result of denunciations, the number of parties falls below 40. Many treaties expressly forbid withdrawal. Article 56 of the Vienna Convention on the Law of Treaties provides that where a treaty is silent over whether or not it can be denounced there is a rebuttable presumption that it cannot be unilaterally denounced unless: it can be shown that the parties intended to admit the possibility, or a right of withdrawal can be inferred from the terms of the treaty. The possibility of withdrawal depends on the terms of the treaty and its travaux preparatory. It has, for example, been held that it is not possible to withdraw from the International Covenant on Civil and Political Rights. When North Korea declared its intention to do this the Secretary-General of the United Nations, acting as registrar, said that original signatories of the ICCPR had not overlooked the possibility of explicitly providing for withdrawal, but rather had deliberately intended not to provide for it. Consequently, withdrawal was not possible. The Organization of American States(OAS) offers the ability of member states to withdraw from its framework by allowing states to officially inform the General Secretariat of the OAS of such intended withdrawal and being subject to a two-year long sunset period in accordance with Article 143 of the body's charter. In practice, state legislatures or other officials where so structured sometimes use their sovereignty or provisions of supreme law to declare their withdrawal from and stop following the terms of a treaty even if this violates the terms of the treaty. Other parties may accept this outcome, may consider the state to be untrustworthy in future dealings, or may retaliate with sanctions or military action. Withdrawal by one party from a bilateral treaty is typically considered to terminate the treaty. Multilateral treaties typically continue even after the withdrawal of one member, unless the terms of the treaty or mutual agreement causes its termination. --Suspension and termination-- If a party has materially violated or breached its treaty obligations, the other parties may invoke this breach as grounds for temporarily suspending their obligations to that party under the treaty. A material breach may also be invoked as grounds for permanently terminating the treaty itself. A treaty breach does not automatically suspend or terminate treaty relations, however. It depends on how the other parties regard the breach and how they resolve to respond to it. Sometimes treaties will provide for the seriousness of a breach to be determined by a tribunal or other independent arbiter. An advantage of such an arbiter is that it prevents a party from prematurely and perhaps wrongfully suspending or terminating its own obligations due to another's an alleged material breach. Treaties sometimes include provisions for self-termination, meaning that the treaty is automatically terminated if certain defined conditions are met. Some treaties are intended by the parties to be only temporarily binding and are set to expire on a given date. Other treaties may self-terminate if the treaty is meant to exist only under certain conditions. A party may claim that a treaty should be terminated, even absent an express provision, if there has been a fundamental change in circumstances. Such a change is sufficient if unforeseen, if it undermined the "essential basis" of consent by a party if it radically transforms the extent of obligations between the parties, and if the obligations are still to be performed. A party cannot base this claim on change brought about by its own breach of the treaty. This claim also cannot be used to invalidate treaties that established or redrew political boundaries. -Cartels- Cartels("Cartells", "Cartelle" or "Kartell-Konventionen" in other languages) were a special kind of treaty within the international law of the 17th to 19th centuries. Their purpose was to regulate specific activities of common interest among contracting states that otherwise remained rivals in other areas. They were typically implemented on an administrative level. Similar to the cartels for duels and tournaments, these intergovernmental accords represented fairness agreements or gentlemen's agreements between states. In the United States, cartels governed humanitarian actions typically carried out by cartel ships were dispatched for missions, such as to carry communications or prisoners between belligerents. From the European history, a broader range of purposes is known. These "cartels" often reflected the cohesion of authoritarian ruling classes against their own unruly citizens. Generally, the European governments concluded - while curbing their mutual rivalries partially - cooperation agreements, which should apply generally or only in case of war: Deserters, escaped serfs and criminals were to be mutually extradited. Prisoners of war should be handed out according to rank in different exchange ratios. The maintenance of postal and commercial traffic including the entry and exit of couriers should be guaranteed in the fields of communication and transport. "Customs cartels"("Zollkartelle") and "coin cartels"("Münzkartelle") were "regulatory" agreements between Continental-European states in the 19th century. Against smugglers and counterfeiters, a joint action approach was adopted by the governments contracting on international trade treaties. The latter often contained the relevant "cartel" regulations in their annexes. The measures against criminals and unruly citizens were to be conducted regardless of the nationality and origin of the relevant persons. If necessary, national borders could be crossed by police forces of the respective neighboring country for capture and arrest. In the course of the 19th century, the term "cartel"(or "Cartell") gradually disappeared for intergovernmental agreements under international law. Instead, the term "convention" was used. -Invalid treaties- An otherwise valid and agreed upon treaty may be rejected as a binding international agreement on several grounds. For example, the Japan–Korea treaties of 1905, 1907, and 1910 were protested by several governments as having been essentially forced upon Korea by Japan; they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea. --Ultra vires treaties-- If an act or lack thereof is condemned under international law, the act will not assume international legality even if approved by internal law. This means that in case of a conflict with domestic law, international law will always prevail. A party's consent to a treaty is invalid if it had been given by an agent or body without power to do so under that state's domestic laws. States are reluctant to inquire into the internal affairs and processes of other states, and so a "manifest violation" is required such that it would be "objectively evident to any State dealing with the matter". A strong presumption exists internationally that a head of state has acted within his proper authority. It seems that no treaty has ever actually been invalidated on this provision. Consent is also invalid if it was given by a representative acting outside their restricted powers during the negotiations, if the other parties to the treaty were notified of those restrictions prior to his or her signing. --Misunderstanding, fraud, corruption, coercion-- Articles 46–53 of the Vienna Convention on the Law of Treaties set out the only ways that treaties can be invalidated—considered unenforceable and void under international law. A treaty will be invalidated due to either the circumstances by which a state party joined the treaty or due to the content of the treaty itself. Invalidation is separate from withdrawal, suspension, or termination(addressed above), which all involve an alteration in the consent of the parties of a previously valid treaty rather than the invalidation of that consent in the first place. A governmental leader's consent may be invalidated if there was an erroneous understanding of a fact or situation at the time of conclusion, which formed the "essential basis" of the state's consent. Consent will not be invalidated if the misunderstanding was due to the state's own conduct, or if the truth should have been evident. Consent will also be invalidated if it was induced by the fraudulent conduct of another party, or by the direct or indirect "corruption" of its representative by another party to the treaty. Coercion of either a representative or the state itself through the threat or use of force, if used to obtain the consent of that state to a treaty, will invalidate that consent. --Contrary to peremptory norms-- A treaty is null and void if it is in violation of a peremptory norm. These norms, unlike other principles of customary law, are recognized as permitting no violations and so cannot be altered through treaty obligations. These are limited to such universally accepted prohibitions as those against the aggressive use of force, genocide and other crimes against humanity, piracy, hostilities directed at civilian population, racial discrimination and apartheid, slavery and torture, meaning that no state can legally assume an obligation to commit or permit such acts. -Treaties under domestic national law- --Australia-- The constitution of Australia allows the executive government to enter into treaties, but the practice is for treaties to be tabled in both houses of parliament at least 15 days before signing. Treaties are considered a source of Australian law but sometimes require an act of parliament to be passed depending on their nature. Treaties are administered and maintained by the Department of Foreign Affairs and Trade, which advised that the "general position under Australian law is that treaties which Australia has joined, apart from those terminating a state of war, are not directly and automatically incorporated into Australian law. Signature and ratification do not, of themselves, make treaties operate domestically. In the absence of legislation, treaties cannot impose obligations on individuals nor create rights in domestic law. Nevertheless, international law, including treaty law, is a legitimate and important influence on the development of the common law and may be used in the interpretation of statutes." Treaties can be implemented by executive action, and often, existing laws are sufficient to ensure a treaty is honored. Australian treaties generally fall under the following categories: extradition, postal agreements and money orders, trade and international conventions. --Brazil-- The federal constitution of Brazil states that the power to enter into treaties is vested in the president of Brazil and that such treaties must be approved by the Congress of Brazil(Articles 84, Clause VIII, and 49, Clause I). In practice, that has been interpreted as meaning that the executive branch is free to negotiate and sign a treaty but that its ratification by the president requires the prior approval of Congress. Additionally, the Supreme Federal Court has ruled that after ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register for it to be valid in Brazil and applicable by the Brazilian authorities. The court has established that treaties are subject to constitutional review and enjoy the same hierarchical position as ordinary legislation(leis ordinárias, or "ordinary laws", in Portuguese). A more recent ruling by the Supreme Court of Brazil in 2008 has altered that somewhat by stating that treaties containing human rights provisions enjoy a status above that of ordinary legislation, subject to only the constitution itself. Additionally, the 45th Amendment to the constitution makes human rights treaties approved by Congress by a special procedure enjoy the same hierarchical position as a constitutional amendment. The hierarchical position of treaties in relation to domestic legislation is of relevance to the discussion on whether and how the latter can abrogate the former and vice versa. The constitution does not have an equivalent to the supremacy clause in United States Constitution, which is of interest to the discussion on the relation between treaties and legislation of the states of Brazil. --India-- In India, subjects are divided into three lists: union, state and concurrent. In the normal legislation process, the subjects on the union list must be legislated by the Parliament of India. For subjects on the state list, only the respective state legislature can legislate. For subjects on the concurrent list, both governments can make laws. However, to implement international treaties, Parliament can legislate on any subject and even override the general division of subject lists. --United States-- In the United States, the term "treaty" has a distinct and more restricted legal definition than in international law. U.S. law distinguishes between "treaties", as defined in the U.S. Constitution, and "executive agreements", which are either "congressional-executive agreements" or "sole executive agreements"; although all three classes are equally treaties under international law, they are subject to different political and legal requirements and implications in the U.S. The distinctions primarily concern the method of approval: Treaties require the "advice and consent" by two-thirds of the Senators present, whereas sole executive agreements are executed by the President acting alone and congressional-executive agreements require majority approval by both the House and the Senate. The three classifications are not mutually exclusive: A treaty may require a simple majority in Congress before or after it is signed by the President or may grant the President authority to fill in the gaps with executive agreements, rather than additional treaties or protocols. Currently, international agreements are ten times more likely to be executed by executive agreement, due to their relative ease. Nevertheless, the President still often chooses to pursue the formal treaty process over an executive agreement to gain congressional support on matters that require Congress to pass implementing legislation or appropriate funds as well as for agreements that impose long-term, complex legal obligations on the U.S. For example, the agreement by the United States, Iran, and other countries is not a treaty under U.S. law, but rather a "political commitment" that does not bind the parties by law. The nuances and ambiguity of how international agreements are effectuated or implemented in U.S. law has been subject to multiple legal cases. The U.S. Supreme Court ruled in the Head Money Cases(1884) that "treaties" do not have a privileged position over acts of Congress and can be repealed or modified by legislative action just like any other regular law. In a similar vein, the court's decision in Reid v. Covert(1957) held that treaty provisions that conflict with the U.S. Constitution are null and void under U.S. law. However, the U.S. Supreme Court has also recognized the "supremacy" of treaties in the U.S. Constitution, such as in Ware v. Hylton(1796) and Missouri v. Holland(1920). The relative ease by which certain international agreements could be entered into by the President has often prompted congressional pushback, most notably in the proposed Bricker Amendment to the U.S. Constitution, which explicitly sought to reign in executive treatymaking powers. -Treaties and indigenous peoples- Treaties formed an important part of European colonization; in many parts of the world, Europeans attempted to legitimize their sovereignty by signing treaties with indigenous peoples. In most cases, these treaties were in extremely disadvantageous terms to the native people, who often did not comprehend the implications of what they were signing. In some rare cases, such as with Ethiopia and Qing China, local governments were able to use the treaties to at least mitigate the impact of European colonization. This involved learning the intricacies of European diplomatic customs and then using the treaties to prevent power from overstepping their agreement or by playing different powers against each other. In other cases, such as New Zealand with the Māori and Canada with its First Nations people, treaties allowed native peoples to maintain a minimum amount of autonomy. Such treaties between colonizers and indigenous peoples are an important part of political discourse in the late 20th and early 21st century, the treaties being discussed have international standing as has been stated in a treaty study by the UN. --Australia-- In the case of Indigenous Australians, no treaty was ever entered into with the Indigenous peoples entitling the Europeans to land ownership, mostly adopting the doctrine of terra nullius(with the exception of South Australia). This concept was later overturned by Mabo v Queensland, which established the concept of native title in Australia well after colonization was already a fait accompli. ---Victoria--- On 10 December 2019, the Victorian First Peoples' Assembly met for the first time in the Upper House of the Parliament of Victoria in Melbourne. The main aim of the Assembly is to work out the rules by which individual treaties would be negotiated between the Victorian Government and individual Aboriginal Victorian peoples. It will also establish an independent Treaty Authority, which will oversee the negotiations between the Aboriginal groups and the Victorian Government and ensure fairness. --United States-- Prior to 1871, the government of the United States regularly entered into treaties with Native Americans but the Indian Appropriations Act of 3 March 1871 had a rider attached that effectively ended the President's treaty-making by providing that no Indian nation or tribe shall be acknowledged as an independent nation, tribe, or power with whom the United States may contract by treaty. The federal government continued to provide similar contractual relations with the Indian tribes after 1871 by agreements, statutes, and executive orders. --Canada-- Colonization in Canada saw a number of treaties signed between European settlers and Indigenous First Nations peoples. Historic Canadian treaties tend to fall into three broad categories: commercial, alliance, and territorial. Commercial treaties first emerged in the 17th century and were agreements made between the European fur trading companies and the local First Nations. The Hudson's Bay Company, a British trading company located in what is now Northern Ontario, signed numerous commercial treaties during this period. Alliance treaties, commonly referred to as "treaties of peace, friendship and alliance" emerged in the late 17th to early 18th century. Finally, territorial treaties dictating land rights were signed between 1760 and 1923. The Royal Proclamation of 1763 accelerated the treaty-making process and provided the Crown with access to large amounts of land occupied by the First Nations. The Crown and 364 First Nations signed 70 treaties that are recognized by the Government of Canada and represent over 600,000 First Nation individuals. The treaties are as follows: Treaties of Peace and Neutrality(1701–1760) Peace and Friendship Treaties(1725–1779) Upper Canada Land Surrenders(including Toronto Purchase(Treaty 13), Johnson-Butler Purchase(Gunshot Treaty)) and the Williams Treaties(1764–1862/1923) Robinson Treaties and Douglas Treaties(1850–1854) The Numbered Treaties(1871–1921) ---Treaty perceptions--- There is evidence that "although both Indigenous and European Nations engaged in treaty-making before contact with each other, the traditions, beliefs, and worldviews that defined concepts such as "treaties" were extremely different". The Indigenous understanding of treaties is based on traditional culture and values. Maintaining healthy and equitable relationships with other nations, as well as the environment, is paramount. Gdoo-naaganinaa, a historic treaty between the Nishnaabeg nation and the Haudenosaunee Confederacy is an example of how First Nations approach treaties. Under Gdoo-naaganinaa, also referred-to in English as Our Dish, the neighbouring nations acknowledged that while they were separate nations they shared the same ecosystem or Dish. It was agreed that the nations would respectably share the land, not interfering with the other nation's sovereignty while also not monopolizing environmental resources. First Nations agreements, such as the Gdoo-naaganigaa, are considered "living treaties" that must be upheld continually and renewed over time. European settlers in Canada had a different perception of treaties. Treaties were not a living, equitable agreement but rather a legal contract over which the future creation of Canadian law would later rely on. As time passed, the settlers did not think it necessary to abide by all treaty agreements. A review of historic treaties reveals that the European settler understanding is the dominant view portrayed in Canadian treaties. ---Treaties today--- Canada today recognizes 25 additional treaties called Modern Treaties. These treaties represent the relationships between 97 Indigenous groups which includes over 89,000 people. The treaties have been instrumental in strengthening Indigenous stronghold in Canada by providing the following(as organized by the Government of Canada): Indigenous ownership over 600,000 km² of land(almost the size of Manitoba) capital transfers of over $3.2 billion protection of traditional ways of life access to resource development opportunities participation in land and resources management decisions certainty with respect to land rights in round 40% of Canada's land mass associated self-government rights and political recognition -Notes- A peace treaty is an agreement between two or more hostile parties, usually countries or governments, which formally ends a state of war between the parties. It is different from an armistice, which is an agreement to stop hostilities; a surrender, in which an army agrees to give up arms; or a ceasefire or truce, in which the parties may agree to temporarily or permanently stop fighting. The need for a peace treaty in modern diplomacy arises from the fact that even when a war is actually over and fighting has ceased, the legal state of war is not automatically terminated upon the end of actual fighting and the belligerent parties are still legally defined as enemies. This is evident from the definition of a "state of war" as "a legal state created and ended by official declaration regardless of actual armed hostilities and usually characterized by operation of the rules of war". As a result, even when hostilities are over, a peace treaty is required for the former belligerents in order to reach an, agreement on all issues involved in transition to a legal state of peace.

Rock is a broad genre of popular music that originated in the United States as "rock and roll" in the late 1940s and early 1950s, developing into a range of different styles from the mid-1960s, primarily in the United States and the United Kingdom. It has its roots in rock and roll, a style that drew directly from the black musical genres of blues and rhythm and blues, as well as from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz and other musical styles. For instrumentation, rock is typically centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a 44 time signature and using a verse–chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. Rock was the most popular genre of music in the U.S. and much of the Western world from the 1950s until its decline in the 2010s. Rock musicians in the mid-1960s began to advance the album ahead of the single as the dominant form of recorded music expression and consumption, with the Beatles at the forefront of this development. Their contributions lent the genre a cultural legitimacy in the mainstream and initiated a rock-informed album era in the music industry for the next several decades. By the late 1960s "classic rock" period, a few distinct rock music subgenres had emerged, including hybrids like blues rock, folk rock, country rock, Southern rock, raga rock, and jazz rock, which contributed to the development of psychedelic rock, influenced by the countercultural psychedelic and hippie scene. New genres that emerged included progressive rock, which extended artistic elements, heavy metal, which emphasized an aggressive thick sound, and glam rock, which highlighted showmanship and visual style. In the second half of the 1970s, punk rock reacted by producing stripped-down, energetic social and political critiques. Punk was an influence in the 1980s on new wave, post-punk and eventually alternative rock. From the 1990s, alternative rock began to dominate rock music and break into the mainstream in the form of grunge, Britpop, and indie rock. Further fusion subgenres have since emerged, including pop-punk, electronic rock, rap rock, and rap metal. Some movements were conscious attempts to revisit rock's history, including the garage rock and post-punk revival in the 2000s. Since the 2010s, rock has lost its position as the pre-eminent popular music genre in world culture, but remains commercially successful. The increased influence of hip-hop and electronic dance music can be seen in rock music, notably in the techno-pop scene of the early 2010s and the pop-punk-hip-hop revival of the 2020s. Rock has also embodied and served as the vehicle for cultural and social movements, leading to major subcultures including mods and rockers in the U.K., the hippie movement and the wider Western counterculture movement that spread out from San Francisco in the U.S. in the 1960s, the latter of which continues to this day. Similarly, 1970s punk culture spawned the goth, punk, and emo subcultures. Inheriting the folk tradition of the protest song, rock music has been associated with political activism, as well as changes in social attitudes to race, sex, and drug use, and is often seen as an expression of youth revolt against adult consumerism and conformity. At the same time, it has been commercially highly successful, leading to accusations of selling out. -Characteristics- The sound of rock is traditionally centered on the amplified electric guitar, which emerged in its modern form in the 1950s with the popularity of rock and roll. It was also greatly influenced by the sounds of electric blues guitarists. The sound of an electric guitar in rock music is typically supported by an electric bass guitar, which pioneered jazz music in the same era, and by percussion produced from a drum kit that combines drums and cymbals. This trio of instruments has often been complemented by the inclusion of other instruments, particularly keyboards such as the piano, the Hammond organ, and the synthesizer. The basic rock instrumentation was derived from the basic blues band instrumentation(prominent lead guitar, second chordal instrument, bass, and drums). A group of musicians performing rock music is termed as a rock band or a rock group. Furthermore, it typically consists of between three(the power trio) and five members. Classically, a rock band takes the form of a quartet whose members cover one or more roles, including vocalist, lead guitarist, rhythm guitarist, bass guitarist, drummer, and often keyboard player or another instrumentalist. Rock music is traditionally built on a foundation of simple syncopated rhythms in a 44 meter, with a repetitive snare drum back beat on beats two and four. Melodies often originate from older musical modes such as the Dorian and Mixolydian, as well as major and minor modes. Harmonies range from the common triad to parallel perfect fourths and fifths and dissonant harmonic progressions. Since the late 1950s, and particularly from the mid-1960s onwards, rock music often used the verse–chorus structure derived from blues and folk music, but there has been considerable variation from this model. Critics have stressed the eclecticism and stylistic diversity of rock. Because of its complex history and its tendency to borrow from other musical and cultural forms, it has been argued that "it is impossible to bind rock music to a rigidly delineated musical definition." In 1981, music journalist Robert Christgau said, "the best rock jolts folk-art virtues—directness, utility, natural audience—into the present with shots of modern technology and modernist dissociation". Unlike many earlier styles of popular music, rock lyrics have dealt with a wide range of themes, including romantic love, sex, rebellion against "The Establishment", social concerns, and life styles. These themes were inherited from a variety of sources such as the Tin Pan Alley pop tradition, folk music, and rhythm and blues. Christgau characterizes rock lyrics as a "cool medium" with simple diction and repeated refrains, and asserts that rock's primary "function" "pertains to music, or, more generally, noise." The predominance of white, male, and often middle class musicians in rock music has often been noted, and rock has been seen as an appropriation of Black musical forms for a young, white and largely male audience. As a result, it has also been seen to articulate the concerns of this group in both style and lyrics. Christgau, writing in 1972, said in spite of some exceptions, "rock and roll usually implies an identification of male sexuality and aggression". Since the term "rock" started being used in preference to "rock and roll" from the late 1960s, it has usually been contrasted with pop music, with which it has shared many characteristics; however, rock is often distanced from pop; the former has an emphasis on musicianship, live performance, and a focus on serious and progressive themes as part of an ideology of authenticity that is frequently combined with an awareness of the genre's history and development. According to Simon Frith, rock was "something more than pop, something more than rock and roll" and "[r]ock musicians combined an emphasis on skill and technique with the romantic concept of art as artistic expression, original and sincere". In the new millennium, the term rock has occasionally been used as a blanket term including forms like pop music, reggae music, soul music, and even hip hop, which it has been influenced with but often contrasted through much of the latter's history. Christgau has used the term broadly to refer to popular and semipopular music that caters to his sensibility as "a rock-and-roller", including a fondness for a good beat, a meaningful lyric with some wit, and the theme of youth, which holds an "eternal attraction" so objective "that all youth music partakes of sociology and the field report." Writing in Christgau's Record Guide: The '80s(1990), he said this sensibility is evident in the music of folk singer-songwriter Michelle Shocked, rapper LL Cool J, and synth-pop duo Pet Shop Boys—"all kids working out their identities"—as much as it is in the music of Chuck Berry, the Ramones, and the Replacements. -1940s–1950s: Birth of rock and roll- --Rock and roll-- The foundations of rock music are in rock and roll, which originated in the United States during the late 1940s and early 1950s; the genre quickly spread to much of the rest of the world. Its immediate origins lay in a melding of various black musical genres of the time, including rhythm and blues and gospel music, with country and western. Debate surrounds the many recordings which have been suggested as "the first rock and roll record". Contenders include "Strange Things Happening Every Day" by Sister Rosetta Tharpe(1944); "That's All Right" by Arthur Crudup(1946), which was later covered by Elvis Presley in 1954; "The House of Blue Lights" by Ella Mae Morse and Freddie Slack(1946); Wynonie Harris' "Good Rocking Tonight"(1948); Goree Carter's "Rock Awhile"(1949); Jimmy Preston's "Rock the Joint"(1949), also covered by Bill Haley & His Comets in 1952; and "Rocket 88" by Jackie Brenston and his Delta Cats(in fact, Ike Turner and his band the Kings of Rhythm), recorded by Sam Phillips for Chess Records in 1951. In 1951, Cleveland, Ohio disc jockey Alan Freed began playing rhythm and blues music(then termed "race music") for a multi-racial audience, and is credited with first using the phrase "rock and roll" to describe the music. Four years later, Bill Haley's "Rock Around the Clock"(1954) became the first rock and roll song to top Billboard magazine's main sales and airplay charts, and opened the door worldwide for this new wave of popular culture. Other artists with early rock and roll hits included Chuck Berry, Bo Diddley, Fats Domino, Little Richard, Jerry Lee Lewis, and Gene Vincent. Soon rock and roll was the major force in American record sales and crooners, such as Eddie Fisher, Perry Como, and Patti Page, who had dominated the previous decade of popular music, found their access to the pop charts significantly curtailed. Rock and roll has been seen as leading to a number of distinct subgenres, including rockabilly, combining rock and roll with "hillbilly" country music, which was usually played and recorded in the mid-1950s by white singers such as Carl Perkins, Jerry Lee Lewis, Roy Orbison, Buddy Holly and with the greatest commercial success, Elvis Presley. Hispanic and Latino American movements in rock and roll, which would eventually lead to the success of Latin rock and Chicano rock within the US, began to rise in the Southwest; with rock and roll standard musician Ritchie Valens and even those within other heritage genres, such as Al Hurricane along with his brothers Tiny Morrie and Baby Gaby as they began combining rock and roll with country-western within traditional New Mexico music. In addition, the 1950s saw the growth in popularity of the electric guitar, and the development of a specifically rock and roll style of playing through such exponents as Chuck Berry, Link Wray, and Scotty Moore. The use of distortion, pioneered by Western swing guitarists such as Junior Barnard and Eldon Shamblin was popularized by Chuck Berry in the mid-1950s. The use of power chords, pioneered by Francisco Tárrega and Heitor Villa-Lobos in the 19th century and later on by Willie Johnson and Pat Hare in the early 1950s, was popularized by Link Wray in the late 1950s. Commentators have traditionally perceived a decline of rock and roll in the late 1950s and early 1960s. By 1959, the death of Buddy Holly, the Big Bopper and Ritchie Valens in a plane crash, the departure of Elvis for the army, the retirement of Little Richard to become a preacher, prosecutions of Jerry Lee Lewis and Chuck Berry and the breaking of the payola scandal(which implicated major figures, including Alan Freed, in bribery and corruption in promoting individual acts or songs), gave a sense that the rock and roll era established at that point had come to an end. --Global spread-- Rock quickly spread out from its origins in the US, associated with the rapid Americanization that was taking place globally in the aftermath of the Second World War. Cliff Richard is credited with one of the first rock and roll hits outside of North America with "Move It"(1959), effectively ushering in the sound of British rock. Several artists, most prominently Tommy Steele from the UK, found success with covers of major American rock and roll hits before the recordings could spread internationally, often translating them into local languages where appropriate. Steele in particular toured Britain, Scandinavia, Australia, the USSR and South Africa from 1955 to 1957, influencing the globalisation of rock. Johnny O'Keefe's 1958 record "Wild One" was one of the earliest Australian rock and roll hits. By the late 1950s, as well as in the American-influenced Western world, rock was popular in communist states such as Yugoslavia, and the USSR, as well as in regions such as South America. In the late 1950s and early 1960s, U.S. blues music and blues rock artists, who had been surpassed by the rise of rock and roll in the US, found new popularity in the UK, visiting with successful tours. Lonnie Donegan's 1955 hit "Rock Island Line" was a major influence and helped to develop the trend of skiffle music groups throughout the country, many of which, including John Lennon's Quarrymen(later the Beatles), moved on to play rock and roll. While former rock and roll market in the US was becoming dominated by lightweight pop and ballads, British rock groups at clubs and local dances were developing a style more strongly influenced by blues-rock pioneers, and were starting to play with an intensity and drive seldom found in white American acts; this influence would go on to shape the future of rock music through the British Invasion. -1960s: British invasion and broadening sound- The first four years of the 1960s has traditionally been seen as an era of hiatus for rock and roll. More recently, some authors have emphasised important innovations and trends in this period without which future developments would not have been possible. While early rock and roll, particularly through the advent of rockabilly, saw the greatest commercial success for male and white performers, in this era, the genre was dominated by black and female artists. Rock and roll had not disappeared entirely from music at the end of the 1950s and some of its energy can be seen in the various dance crazes of the early 1960s, started by Chubby Checker's record "The Twist"(1960). Some music historians have also pointed to important and innovative technical developments that built on rock and roll in this period, including the electronic treatment of sound by such innovators as Joe Meek, and the elaborate production methods of the Wall of Sound pursued by Phil Spector. --Instrumental rock and surf-- The instrumental rock and roll of performers such as Duane Eddy, Link Wray and the Ventures was further developed by Dick Dale, who added distinctive "wet" reverb, rapid alternate picking, and Middle Eastern and Mexican influences. He produced the regional hit "Let's Go Trippin'" in 1961 and launched the surf music craze, following up with songs like "Misirlou"(1962). Like Dale and his Del-Tones, most early surf bands were formed in Southern California, including the Bel-Airs, the Challengers, and Eddie & the Showmen. The Chantays scored a top ten national hit with "Pipeline" in 1963 and probably the best-known surf tune was 1963's "Wipe Out", by the Surfaris, which hit number 2 and number 10 on the Billboard charts in 1965. Surf rock was also popular in Europe during this time, with the British group the Shadows scoring hits in the early 1960s with instrumentals such as "Apache"(1960) and "Kon-Tiki"(1961), while Swedish surf group the Spotnicks saw success in both Sweden and Britain. Surf music achieved its greatest commercial success as vocal pop music, particularly the work of the Beach Boys, formed in 1961 in Southern California. Their early albums included both instrumental surf rock, including covers of music by Dick Dale and vocal songs, drawing on rock and roll and doo wop and the close harmonies of vocal pop acts like the Four Freshmen. The Beach Boys first chart hit, "Surfin'" in 1961 reached the Billboard top 100 and helped make the surf music craze a national phenomenon. It is often argued that the surf music craze and the careers of almost all surf acts was effectively ended by the arrival of the British Invasion from 1964, because most surf music hits were recorded and released between 1960 and 1965. --British Invasion-- By the end of 1962, what would become the British rock scene had started with beat groups like the Beatles, Gerry & the Pacemakers and the Searchers from Liverpool and Freddie and the Dreamers, Herman's Hermits and the Hollies from Manchester. They drew on a wide range of American influences including 1950s rock and roll, soul, rhythm and blues, and surf music, initially reinterpreting standard American tunes and playing for dancers. Bands like the Animals from Newcastle and Them from Belfast, and particularly those from London like the Rolling Stones and the Yardbirds, were much more directly influenced by rhythm and blues and later blues music. Soon these groups were composing their own material, combining US forms of music and infusing it with a high energy beat. Beat bands tended towards "bouncy, irresistible melodies", while early British blues acts tended towards less sexually innocent, more aggressive songs, often adopting an anti-establishment stance. There was, however, particularly in the early stages, considerable musical crossover between the two tendencies. By 1963, led by the Beatles, beat groups had begun to achieve national success in Britain, soon to be followed into the charts by the more rhythm and blues focused acts. "I Want to Hold Your Hand" was the Beatles' first number one hit on the Billboard Hot 100, spending seven weeks at the top and a total of 15 weeks on the chart. Their first appearance on The Ed Sullivan Show on 9 February 1964, drawing an estimated 73 million viewers(at the time a record for an American television program) is considered a milestone in American pop culture. During the week of 4 April 1964, the Beatles held 12 positions on the Billboard Hot 100 singles chart, including the entire top five. The Beatles went on to become the biggest selling rock band of all time and they were followed into the US charts by numerous British bands. During the next two years, British acts dominated their own and the US charts with Peter and Gordon, the Animals, Manfred Mann, Petula Clark, Freddie and the Dreamers, Wayne Fontana and the Mindbenders, Herman's Hermits, the Rolling Stones, the Troggs, and Donovan all having one or more number one singles. Other major acts that were part of the invasion included the Kinks, the Who, and the Dave Clark Five. The British Invasion helped internationalize the production of rock and roll, opening the door for subsequent British(and Irish) performers to achieve international success. In America it arguably spelled the end of instrumental surf music, vocal girl groups and(for a time) the teen idols, that had dominated the American charts in the late 1950s and 1960s. It dented the careers of established R&B acts like Fats Domino and Chubby Checker and even temporarily derailed the chart success of surviving rock and roll acts, including Elvis. The British Invasion also played a major part in the rise of a distinct genre of rock music, and cemented the primacy of the rock group, based on guitars and drums and producing their own material as singer-songwriters. Following the example set by the Beatles' 1965 LP Rubber Soul in particular, other British rock acts released rock albums intended as artistic statements in 1966, including the Rolling Stones' Aftermath, the Beatles' own Revolver, and the Who's A Quick One, as well as American acts in the Beach Boys(Pet Sounds) and Bob Dylan(Blonde on Blonde). --Blues rock-- Although the first impact of the British Invasion on American popular music was through beat and R&B based acts, the impetus was soon taken up by a second wave of bands that drew their inspiration more directly from American blues, including the Rolling Stones and the Yardbirds. British blues musicians of the late 1950s and early 1960s had been inspired by the acoustic playing of figures such as Lead Belly, who was a major influence on the Skiffle craze, and Robert Johnson. Increasingly they adopted a loud amplified sound, often centered on the electric guitar, based on the Chicago blues, particularly after the tour of Britain by Muddy Waters in 1958, which prompted Cyril Davies and guitarist Alexis Korner to form the band Blues Incorporated. The band involved and inspired many of the figures of the subsequent British blues boom, including members of the Rolling Stones and Cream, combining blues standards and forms with rock instrumentation and emphasis. The other key focus for British blues was John Mayall; his band, the Bluesbreakers, included Eric Clapton(after Clapton's departure from the Yardbirds) and later Peter Green. Particularly significant was the release of Blues Breakers with Eric Clapton(Beano) album(1966), considered one of the seminal British blues recordings and the sound of which was much emulated in both Britain and the United States. Eric Clapton went on to form supergroups Cream, Blind Faith, and Derek and the Dominos, followed by an extensive solo career that helped bring blues rock into the mainstream. Green, along with the Bluesbreaker's rhythm section Mick Fleetwood and John McVie, formed Peter Green's Fleetwood Mac, who enjoyed some of the greatest commercial success in the genre. In the late 1960s Jeff Beck, also an alumnus of the Yardbirds, moved blues rock in the direction of heavy rock with his band, the Jeff Beck Group. The last Yardbirds guitarist was Jimmy Page, who went on to form The New Yardbirds which rapidly became Led Zeppelin. Many of the songs on their first three albums, and occasionally later in their careers, were expansions on traditional blues songs. In the United States, blues rock had been pioneered in the early 1960s by guitarist Lonnie Mack; however, the genre began to take off in the mid-1960s as acts developed a sound similar to British blues musicians. Key acts included Paul Butterfield(whose band acted like Mayall's Bluesbreakers in Britain as a starting point for many successful musicians), Canned Heat, the early Jefferson Airplane, Janis Joplin, Johnny Winter, the J. Geils Band, and Jimi Hendrix with his power trios, the Jimi Hendrix Experience(which included two British members, and was founded in Britain), and Band of Gypsys, whose guitar virtuosity and showmanship would be among the most emulated of the decade. Blues rock bands from the southern states, like the Allman Brothers Band, Lynyrd Skynyrd, and ZZ Top, incorporated country elements into their style to produce the distinctive genre Southern rock. Early blues rock bands often emulated jazz, playing long, involved improvisations, which would later be a major element of progressive rock. From about 1967 bands like Cream and the Jimi Hendrix Experience had moved away from purely blues-based music into psychedelia. By the 1970s, blues rock had become heavier and more riff-based, exemplified by the work of Led Zeppelin and Deep Purple, and the lines between blues rock and hard rock "were barely visible", as bands began recording rock-style albums. The genre was continued in the 1970s by figures such as George Thorogood and Pat Travers, but, particularly on the British scene(except perhaps for the advent of groups such as Status Quo and Foghat who moved towards a form of high energy and repetitive boogie rock), bands became focused on heavy metal innovation, and blues rock began to slip out of the mainstream. --Garage rock-- Garage rock was a raw form of rock music, particularly prevalent in North America in the mid-1960s and so called because of the perception that it was rehearsed in the suburban family garage. Garage rock songs often revolved around the traumas of high school life, with songs about "lying girls" and unfair social circumstances being particularly common. The lyrics and delivery tended to be more aggressive than was common at the time, often with growled or shouted vocals that dissolved into incoherent screaming. They ranged from crude one-chord music(like the Seeds) to near-studio musician quality(including the Knickerbockers, the Remains, and the Fifth Estate). There were also regional variations in many parts of the country with flourishing scenes particularly in California and Texas. The Pacific Northwest states of Washington and Oregon had perhaps the most defined regional sound. The style had been evolving from regional scenes as early as 1958. "Tall Cool One"(1959) by the Wailers and "Louie Louie" by the Kingsmen(1963) are mainstream examples of the genre in its formative stages. By 1963, garage band singles were creeping into the national charts in greater numbers, including Paul Revere and the Raiders(Boise), the Trashmen(Minneapolis) and the Rivieras(South Bend, Indiana). Other influential garage bands, such as the Sonics(Tacoma, Washington), never reached the Billboard Hot 100. The British Invasion greatly influenced garage bands, providing them with a national audience, leading many(often surf or hot rod groups) to adopt a British influence, and encouraging many more groups to form. Thousands of garage bands were extant in the United States and Canada during the era and hundreds produced regional hits. Despite scores of bands being signed to major or large regional labels, most were commercial failures. It is generally agreed that garage rock peaked both commercially and artistically around 1966. By 1968, the style largely disappeared from the national charts and at the local level as amateur musicians faced college, work or the draft. New styles had evolved to replace garage rock. --Folk rock-- By the 1960s, the scene that had developed out of the American folk music revival had grown to a major movement, using traditional music and new compositions in a traditional style, usually on acoustic instruments. In America the genre was pioneered by figures such as Woody Guthrie and Pete Seeger and often identified with progressive or labor politics. In the early sixties figures such as Joan Baez and Bob Dylan had come to the fore in this movement as singer-songwriters. Dylan had begun to reach a mainstream audience with hits including "Blowin' in the Wind"(1963) and "Masters of War"(1963), which brought "protest songs" to a wider public, but, although beginning to influence each other, rock and folk music had remained largely separate genres, often with mutually exclusive audiences. Early attempts to combine elements of folk and rock included the Animals' "House of the Rising Sun"(1964), which was the first commercially successful folk song to be recorded with rock and roll instrumentation and the Beatles "I'm a Loser"(1964), arguably the first Beatles song to be influenced directly by Dylan. The folk rock movement is usually thought to have taken off with the Byrds' recording of Dylan's "Mr. Tambourine Man" which topped the charts in 1965. With members who had been part of the café-based folk scene in Los Angeles, the Byrds adopted rock instrumentation, including drums and 12-string Rickenbacker guitars, which became a major element in the sound of the genre. Later that year Dylan adopted electric instruments, much to the outrage of many folk purists, with his "Like a Rolling Stone" becoming a US hit single. According to Ritchie Unterberger, Dylan(even before his adoption of electric instruments) influenced rock musicians like the Beatles, demonstrating "to the rock generation in general that an album could be a major standalone statement without hit singles", such as on The Freewheelin' Bob Dylan(1963). Folk rock particularly took off in California, where it led acts like the Mamas & the Papas and Crosby, Stills, and Nash to move to electric instrumentation, and in New York, where it spawned performers including the Lovin' Spoonful and Simon and Garfunkel, with the latter's acoustic "The Sounds of Silence"(1965) being remixed with rock instruments to be the first of many hits. These acts directly influenced British performers like Donovan and Fairport Convention. In 1969 Fairport Convention abandoned their mixture of American covers and Dylan-influenced songs to play traditional English folk music on electric instruments. This British folk-rock was taken up by bands including Pentangle, Steeleye Span and the Albion Band, which in turn prompted Irish groups like Horslips and Scottish acts like the JSD Band, Spencer's Feat and later Five Hand Reel, to use their traditional music to create a brand of Celtic rock in the early 1970s. Folk-rock reached its peak of commercial popularity in the period 1967–68, before many acts moved off in a variety of directions, including Dylan and the Byrds, who began to develop country rock. However, the hybridization of folk and rock has been seen as having a major influence on the development of rock music, bringing in elements of psychedelia, and helping to develop the ideas of the singer-songwriter, the protest song, and concepts of "authenticity". --Psychedelic rock-- Psychedelic music's LSD-inspired vibe began in the folk scene. The first group to advertise themselves as psychedelic rock were the 13th Floor Elevators from Texas. The Beatles introduced many of the major elements of the psychedelic sound to audiences in this period, such as guitar feedback, the Indian sitar and backmasking sound effects. Psychedelic rock particularly took off in California's emerging music scene as groups followed the Byrds' shift from folk to folk rock from 1965. The psychedelic lifestyle, which revolved around hallucinogenic drugs, had already developed in San Francisco and particularly prominent products of the scene were Big Brother and the Holding Company, the Grateful Dead and Jefferson Airplane. The Jimi Hendrix Experience's lead guitarist, Jimi Hendrix did extended distorted, feedback-filled jams which became a key feature of psychedelia. Psychedelic rock reached its apogee in the last years of the decade. 1967 saw the Beatles release their definitive psychedelic statement in Sgt. Pepper's Lonely Hearts Club Band, including the controversial track "Lucy in the Sky with Diamonds", the Rolling Stones responded later that year with Their Satanic Majesties Request, and Pink Floyd debuted with The Piper at the Gates of Dawn. Key recordings included Jefferson Airplane's Surrealistic Pillow and the Doors' self-titled debut album. These trends peaked in the 1969 Woodstock festival, which saw performances by most of the major psychedelic acts. Sgt. Pepper was later regarded as the greatest album of all time and a starting point for the album era, during which rock music transitioned from the singles format to albums and achieved cultural legitimacy in the mainstream. Led by the Beatles in the mid-1960s, rock musicians advanced the LP as the dominant form of recorded music expression and consumption, initiating a rock-informed album era in the music industry for the next several decades. --Progressive rock-- Progressive rock, a term sometimes used interchangeably with art rock, moved beyond established musical formulas by experimenting with different instruments, song types, and forms. From the mid-1960s, the Left Banke, the Beatles, the Rolling Stones and the Beach Boys, had pioneered the inclusion of harpsichords, wind, and string sections on their recordings to produce a form of Baroque rock and can be heard in singles like Procol Harum's "A Whiter Shade of Pale"(1967), with its Bach-inspired introduction. The Moody Blues used a full orchestra on their album Days of Future Passed(1967) and subsequently created orchestral sounds with synthesizers. Classical orchestration, keyboards, and synthesizers were a frequent addition to the established rock format of guitars, bass, and drums in subsequent progressive rock. Instrumentals were common, while songs with lyrics were sometimes conceptual, abstract, or based in fantasy and science fiction. The Pretty Things' SF Sorrow(1968), the Kinks' Arthur(Or the Decline and Fall of the British Empire)(1969), and the Who's Tommy(1969) introduced the format of rock operas and opened the door to concept albums, often telling an epic story or tackling a grand overarching theme. King Crimson's 1969 début album, In the Court of the Crimson King, which mixed powerful guitar riffs and mellotron, with jazz and symphonic music, is often taken as the key recording in progressive rock, helping the widespread adoption of the genre in the early 1970s among existing blues-rock and psychedelic bands, as well as newly formed acts. The vibrant Canterbury scene saw acts following Soft Machine from psychedelia, through jazz influences, toward more expansive hard rock, including Caravan, Hatfield and the North, Gong, and National Health. The French group Magma around drummer Christian Vander almost single-handedly created the new music genre zeuhl with their first albums in the early 1970s. Greater commercial success was enjoyed by Pink Floyd, who also moved away from psychedelia after the departure of Syd Barrett in 1968, with The Dark Side of the Moon(1973), seen as a masterpiece of the genre, becoming one of the best-selling albums of all time. There was an emphasis on instrumental virtuosity, with Yes showcasing the skills of both guitarist Steve Howe and keyboard player Rick Wakeman, while Emerson, Lake & Palmer were a supergroup who produced some of the genre's most technically demanding work. Jethro Tull and Genesis both pursued very different, but distinctly English, brands of music. Renaissance, formed in 1969 by ex-Yardbirds Jim McCarty and Keith Relf, evolved into a high-concept band featuring the three-octave voice of Annie Haslam. Most British bands depended on a relatively small cult following, but a handful, including Pink Floyd, Genesis, and Jethro Tull, managed to produce top ten singles at home and break the American market. The American brand of progressive rock varied from the eclectic and innovative Frank Zappa, Captain Beefheart and Blood, Sweat & Tears, to more pop rock orientated bands like Boston, Foreigner, Kansas, Journey, and Styx. These, beside British bands Supertramp and ELO, all demonstrated a prog rock influence and while ranking among the most commercially successful acts of the 1970s, heralding the era of pomp or arena rock, which would last until the costs of complex shows(often with theatrical staging and special effects), would be replaced by more economical rock festivals as major live venues in the 1990s. The instrumental strand of the genre resulted in albums like Mike Oldfield's Tubular Bells(1973), the first record, and worldwide hit, for the Virgin Records label, which became a mainstay of the genre. Instrumental rock was particularly significant in continental Europe, allowing bands like Kraftwerk, Tangerine Dream, Can, Focus(band) and Faust to circumvent the language barrier. Their synthesiser-heavy "krautrock", along with the work of Brian Eno(for a time the keyboard player with Roxy Music), would be a major influence on subsequent electronic rock. With the advent of punk rock and technological changes in the late 1970s, progressive rock was increasingly dismissed as pretentious and overblown. Many bands broke up, but some, including Genesis, ELP, Yes, and Pink Floyd, regularly scored top ten albums with successful accompanying worldwide tours. Some bands which emerged in the aftermath of punk, such as Siouxsie and the Banshees, Ultravox, and Simple Minds, showed the influence of progressive rock, as well as their more usually recognized punk influences. --Jazz rock-- In the late 1960s, jazz-rock emerged as a distinct subgenre out of the blues-rock, psychedelic, and progressive rock scenes, mixing the power of rock with the musical complexity and improvisational elements of jazz. AllMusic states that the term jazz-rock "may refer to the loudest, wildest, most electrified fusion bands from the jazz camp, but most often it describes performers coming from the rock side of the equation." Jazz-rock "...generally grew out of the most artistically ambitious rock subgenres of the late '60s and early '70s", including the singer-songwriter movement. Many early US rock and roll musicians had begun in jazz and carried some of these elements into the new music. In Britain, the subgenre of blues rock, and many of its leading figures, like Ginger Baker and Jack Bruce of the Eric Clapton-fronted band Cream, had emerged from the British jazz scene.

A species(pl. species) is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species(except viruses) are given a two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name or the specific epithet(in botanical nomenclature, also sometimes in zoological nomenclature). For example, Boa constrictor is one of the species of the genus Boa, with constrictor being the specific name. While the definitions given above may seem adequate at first glance, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clonal lineage is potentially a microspecies. Although none of these are entirely satisfactory definitions, and while the concept of species may not be a perfect model of life, it is still a useful tool to scientists and conservationists for studying life on Earth, regardless of the theoretical difficulties. If species were fixed and distinct from one another, there would be no problem, but evolutionary processes cause species to change. This obliges taxonomists to decide, for example, when enough change has occurred to declare that a fossil lineage should be divided into multiple chronospecies, or when populations have diverged to have enough distinct character states to be described as cladistic species. Species and higher taxa were seen from Aristotle until the 18th century as categories that could be arranged in a hierarchy, the great chain of being. In the 19th century, biologists grasped that species could evolve given sufficient time. Charles Darwin's 1859 book On the Origin of Species explained how species could arise by natural selection. That understanding was greatly extended in the 20th century through genetics and population ecology. Genetic variability arises from mutations and recombination, while organisms are mobile, leading to geographical isolation and genetic drift with varying selection pressures. Genes can sometimes be exchanged between species by horizontal gene transfer; new species can arise rapidly through hybridisation and polyploidy; and species may become extinct for a variety of reasons. Viruses are a special case, driven by a balance of mutation and selection, and can be treated as quasispecies. -Definition- Biologists and taxonomists have made many attempts to define species, beginning from morphology and moving towards genetics. Early taxonomists such as Linnaeus had no option but to describe what they saw: this was later formalised as the typological or morphological species concept. Ernst Mayr emphasised reproductive isolation, but this, like other species concepts, can be hard or even impossible to test for groups of organisms separated in space or time. Later biologists have tried to refine Mayr's definition with the recognition and cohesion concepts, among others. Many of the concepts are quite similar or overlap, so they are not easy to count: the biologist R. L. Mayden recorded about 24 concepts, and the philosopher of science John Wilkins counted 26. Wilkins further grouped the species concepts into seven basic kinds of concepts:(1) agamospecies for asexual organisms(2) biospecies for reproductively isolated sexual organisms(3) ecospecies based on ecological niches(4) evolutionary species based on lineage(5) genetic species based on gene pool(6) morphospecies based on form or phenotype and(7) taxonomic species, a species as determined by a taxonomist. --Typological or morphological species-- A typological species is a group of organisms in which individuals conform to certain fixed properties(a type, which may be defined by a chosen 'nominal species'), so that even pre-literate people often recognise the same taxon as do modern taxonomists. Modern-day field guides and identification websites such as iNaturalist use this concept. The clusters of variations or phenotypes within specimens(such as longer or shorter tails) would differentiate the species. This method was used as a "classical" method of determining species, such as with Linnaeus, early in evolutionary theory. However, different phenotypes are not necessarily different species(e.g. a four-winged Drosophila born to a two-winged mother is not a different species). Species named in this manner are called morphospecies. In the 1970s, Robert R. Sokal, Theodore J. Crovello and Peter Sneath proposed a variation on the morphological species concept, a phenetic species, defined as a set of organisms with a similar phenotype to each other, but a different phenotype from other sets of organisms. It differs from the morphological species concept in including a numerical measure of distance or similarity to cluster entities based on multivariate comparisons of a reasonably large number of phenotypic traits. --Recognition and cohesion species-- A mate-recognition species is a group of sexually reproducing organisms that recognise one another as potential mates. Expanding on this to allow for post-mating isolation, a cohesion species is the most inclusive population of individuals having the potential for phenotypic cohesion through intrinsic cohesion mechanisms; no matter whether populations can hybridise successfully, they are still distinct cohesion species if the amount of hybridisation is insufficient to completely mix their respective gene pools. A further development of the recognition concept is provided by the biosemiotic concept of species. --Genetic similarity and barcode species-- In microbiology, genes can move freely even between distantly related bacteria, possibly extending to the whole bacterial domain. As a rule of thumb, microbiologists have assumed that members of Bacteria or Archaea with 16S ribosomal RNA gene sequences more similar than 97% to each other need to be checked by DNA–DNA hybridisation to decide if they belong to the same species. This concept was narrowed in 2006 to a similarity of 98.7%. The average nucleotide identity(ANI) method quantifies genetic distance between entire genomes, using regions of about 10,000 base pairs. With enough data from genomes of one genus, algorithms can be used to categorize species, as for Pseudomonas avellanae in 2013, and for all sequenced bacteria and archaea since 2020. Observed ANI values among sequences appear to have an "ANI gap" at 85–95%, suggesting that a genetic boundary suitable for defining a species concept is present. DNA barcoding has been proposed as a way to distinguish species suitable even for non-specialists to use. One of the barcodes is a region of mitochondrial DNA within the gene for cytochrome c oxidase. A database, Barcode of Life Data System, contains DNA barcode sequences from over 190,000 species. However, scientists such as Rob DeSalle have expressed concern that classical taxonomy and DNA barcoding, which they consider a misnomer, need to be reconciled, as they delimit species differently. Genetic introgression mediated by endosymbionts and other vectors can further make barcodes ineffective in the identification of species. --Phylogenetic or cladistic species-- A phylogenetic or cladistic species is "the smallest aggregation of populations(sexual) or lineages(asexual) diagnosable by a unique combination of character states in comparable individuals(semaphoronts)". The empirical basis – observed character states – provides the evidence to support hypotheses about evolutionarily divergent lineages that have maintained their hereditary integrity through time and space. Molecular markers may be used to determine diagnostic genetic differences in the nuclear or mitochondrial DNA of various species. For example, in a study done on fungi, studying the nucleotide characters using cladistic species produced the most accurate results in recognising the numerous fungi species of all the concepts studied. Versions of the phylogenetic species concept that emphasise monophyly or diagnosability may lead to splitting of existing species, for example in Bovidae, by recognising old subspecies as species, despite the fact that there are no reproductive barriers, and populations may intergrade morphologically. Others have called this approach taxonomic inflation, diluting the species concept and making taxonomy unstable. Yet others defend this approach, considering "taxonomic inflation" pejorative and labelling the opposing view as "taxonomic conservatism"; claiming it is politically expedient to split species and recognise smaller populations at the species level, because this means they can more easily be included as endangered in the IUCN red list and can attract conservation legislation and funding. Unlike the biological species concept, a cladistic species does not rely on reproductive isolation – its criteria are independent of processes that are integral in other concepts. Therefore, it applies to asexual lineages. However, it does not always provide clear cut and intuitively satisfying boundaries between taxa, and may require multiple sources of evidence, such as more than one polymorphic locus, to give plausible results. --Evolutionary species-- An evolutionary species, suggested by George Gaylord Simpson in 1951, is "an entity composed of organisms which maintains its identity from other such entities through time and over space, and which has its own independent evolutionary fate and historical tendencies". This differs from the biological species concept in embodying persistence over time. Wiley and Mayden stated that they see the evolutionary species concept as "identical" to Willi Hennig's species-as-lineages concept, and asserted that the biological species concept, "the several versions" of the phylogenetic species concept, and the idea that species are of the same kind as higher taxa are not suitable for biodiversity studies(with the intention of estimating the number of species accurately). They further suggested that the concept works for both asexual and sexually-reproducing species. A version of the concept is Kevin de Queiroz's "General Lineage Concept of Species". --Ecological species-- An ecological species is a set of organisms adapted to a particular set of resources, called a niche, in the environment. According to this concept, populations form the discrete phenetic clusters that we recognise as species because the ecological and evolutionary processes controlling how resources are divided up tend to produce those clusters. --Genetic species-- A genetic species as defined by Robert Baker and Robert Bradley is a set of genetically isolated interbreeding populations. This is similar to Mayr's Biological Species Concept, but stresses genetic rather than reproductive isolation. In the 21st century, a genetic species could be established by comparing DNA sequences. Earlier, other methods were available, such as comparing karyotypes(sets of chromosomes) and allozymes(enzyme variants). --Evolutionarily significant unit-- An evolutionarily significant unit(ESU) or "wildlife species" is a population of organisms considered distinct for purposes of conservation. --Chronospecies-- In palaeontology, with only comparative anatomy(morphology) and histology from fossils as evidence, the concept of a chronospecies can be applied. During anagenesis(evolution, not necessarily involving branching), some palaeontologists seek to identify a sequence of species, each one derived from the phyletically extinct one before through continuous, slow and more or less uniform change. In such a time sequence, some palaeontologists assess how much change is required for a morphologically distinct form to be considered a different species from its ancestors. --Viral quasispecies-- Viruses have enormous populations, are doubtfully living since they consist of little more than a string of DNA or RNA in a protein coat, and mutate rapidly. All of these factors make conventional species concepts largely inapplicable. A viral quasispecies is a group of genotypes related by similar mutations, competing within a highly mutagenic environment, and hence governed by a mutation–selection balance. It is predicted that a viral quasispecies at a low but evolutionarily neutral and highly connected(that is, flat) region in the fitness landscape will outcompete a quasispecies located at a higher but narrower fitness peak in which the surrounding mutants are unfit, "the quasispecies effect" or the "survival of the flattest". There is no suggestion that a viral quasispecies resembles a traditional biological species. The International Committee on Taxonomy of Viruses has since 1962 developed a universal taxonomic scheme for viruses; this has stabilised viral taxonomy. --Mayr's biological species concept-- Most modern textbooks make use of Ernst Mayr's 1942 definition, known as the biological species concept, as a basis for further discussion on the definition of species. It is also called a reproductive or isolation concept. This defines a species as groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups. It has been argued that this definition is a natural consequence of the effect of sexual reproduction on the dynamics of natural selection. Mayr's use of the adjective "potentially" has been a point of debate; some interpretations exclude unusual or artificial matings that occur only in captivity, or that involve animals capable of mating but that do not normally do so in the wild. -The species problem- It is difficult to define a species in a way that applies to all organisms. The debate about species concepts is called the species problem. The problem was recognised even in 1859, when Darwin wrote in On the Origin of Species: I was much struck how entirely vague and arbitrary is the distinction between species and varieties. He went on to write: No one definition has satisfied all naturalists; yet every naturalist knows vaguely what he means when he speaks of a species. Generally the term includes the unknown element of a distinct act of creation. --When Mayr's concept breaks down-- Many authors have argued that a simple textbook definition, following Mayr's concept, works well for most multi-celled organisms, but breaks down in several situations: When organisms reproduce asexually, as in single-celled organisms such as bacteria and other prokaryotes, and parthenogenetic or apomictic multi-celled organisms. DNA barcoding and phylogenetics are commonly used in these cases. The term quasispecies is sometimes used for rapidly mutating entities like viruses. When scientists do not know whether two morphologically similar groups of organisms are capable of interbreeding; this is the case with all extinct life-forms in palaeontology, as breeding experiments are not possible. When hybridisation permits substantial gene flow between species. In ring species, when members of adjacent populations in a widely continuous distribution range interbreed successfully but members of more distant populations do not. Species identification is made difficult by discordance between molecular and morphological investigations; these can be categorised as two types:(i) one morphology, multiple lineages(e.g. morphological convergence, cryptic species) and(ii) one lineage, multiple morphologies(e.g. phenotypic plasticity, multiple life-cycle stages). In addition, horizontal gene transfer(HGT) makes it difficult to define a species. All species definitions assume that an organism acquires its genes from one or two parents very like the "daughter" organism, but that is not what happens in HGT. There is strong evidence of HGT between very dissimilar groups of prokaryotes, and at least occasionally between dissimilar groups of eukaryotes, including some crustaceans and echinoderms. The evolutionary biologist James Mallet concludes that there is no easy way to tell whether related geographic or temporal forms belong to the same or different species. Species gaps can be verified only locally and at a point of time. One is forced to admit that Darwin's insight is correct: any local reality or integrity of species is greatly reduced over large geographic ranges and time periods. The botanist Brent Mishler argued that the species concept is not valid, notably because gene flux decreases gradually rather than in discrete steps, which hampers objective delimitation of species. Indeed, complex and unstable patterns of gene flux have been observed in cichlid teleosts of the East African Great Lakes. Wilkins argued that "if we were being true to evolution and the consequent phylogenetic approach to taxa, we should replace it with a 'smallest clade' idea"(a phylogenetic species concept). Mishler and Wilkins and others concur with this approach, even though this would raise difficulties in biological nomenclature. Wilkins cited the ichthyologist Charles Tate Regan's early 20th century remark that "a species is whatever a suitably qualified biologist chooses to call a species". Wilkins noted that the philosopher Philip Kitcher called this the "cynical species concept", and arguing that far from being cynical, it usefully leads to an empirical taxonomy for any given group, based on taxonomists' experience. Other biologists have gone further and argued that we should abandon species entirely, and refer to the "Least Inclusive Taxonomic Units"(LITUs), a view that would be coherent with current evolutionary theory. --Aggregates of microspecies-- The species concept is further weakened by the existence of microspecies, groups of organisms, including many plants, with very little genetic variability, usually forming species aggregates. For example, the dandelion Taraxacum officinale and the blackberry Rubus fruticosus are aggregates with many microspecies—perhaps 400 in the case of the blackberry and over 200 in the dandelion, complicated by hybridisation, apomixis and polyploidy, making gene flow between populations difficult to determine, and their taxonomy debatable. Species complexes occur in insects such as Heliconius butterflies, vertebrates such as Hypsiboas treefrogs, and fungi such as the fly agaric. --Hybridisation-- Natural hybridisation presents a challenge to the concept of a reproductively isolated species, as fertile hybrids permit gene flow between two populations. For example, the carrion crow Corvus corone and the hooded crow Corvus cornix appear and are classified as separate species, yet they can hybridise where their geographical ranges overlap. Hybridisation of carrion and hooded crows permits gene flow between 'species' --Ring species-- A ring species is a connected series of neighbouring populations, each of which can sexually interbreed with adjacent related populations, but for which there exist at least two "end" populations in the series, which are too distantly related to interbreed, though there is a potential gene flow between each "linked" population. Such non-breeding, though genetically connected, "end" populations may co-exist in the same region thus closing the ring. Ring species thus present a difficulty for any species concept that relies on reproductive isolation. However, ring species are at best rare. Proposed examples include the herring gull–lesser black-backed gull complex around the North pole, the Ensatina eschscholtzii group of 19 populations of salamanders in America, and the greenish warbler in Asia, but many so-called ring species have turned out to be the result of misclassification leading to questions on whether there really are any ring species. -Taxonomy and naming- --Common and scientific names-- The commonly used names for kinds of organisms are often ambiguous: "cat" could mean the domestic cat, Felis catus, or the cat family, Felidae. Another problem with common names is that they often vary from place to place, so that puma, cougar, catamount, panther, painter and mountain lion all mean Puma concolor in various parts of America, while "panther" may also mean the jaguar(Panthera onca) of Latin America or the leopard(Panthera pardus) of Africa and Asia. In contrast, the scientific names of species are chosen to be unique and universal(except for some inter-code homonyms); they are in two parts used together: the genus as in Puma, and the specific epithet as in concolor. --Species description-- A species is given a taxonomic name when a type specimen is described formally, in a publication that assigns it a unique scientific name. The description typically provides means for identifying the new species, which may not be based solely on morphology(see cryptic species), differentiating it from other previously described and related or confusable species and provides a validly published name(in botany) or an available name(in zoology) when the paper is accepted for publication. The type material is usually held in a permanent repository, often the research collection of a major museum or university, that allows independent verification and the means to compare specimens. Describers of new species are asked to choose names that, in the words of the International Code of Zoological Nomenclature, are "appropriate, compact, euphonious, memorable, and do not cause offence". --Abbreviations-- Books and articles sometimes intentionally do not identify species fully, using the abbreviation "sp." in the singular or "spp. "(standing for species pluralis, Latin for "multiple species") in the plural in place of the specific name or epithet(e.g. "Canis sp."). This commonly occurs when authors are confident that some individuals belong to a particular genus but are not sure to which exact species they belong, as is common in paleontology. Authors may also use "spp." as a short way of saying that something applies to many species within a genus, but not to all. If scientists mean that something applies to all species within a genus, they use the genus name without the specific name or epithet. The names of genera and species are usually printed in italics. However, abbreviations such as "sp." should not be italicised. When a species' identity is not clear, a specialist may use "cf." before the epithet to indicate that confirmation is required. The abbreviations "nr."(near) or "aff."(affine) may be used when the identity is unclear but when the species appears to be similar to the species mentioned after. --Identification codes-- With the rise of online databases, codes have been devised to provide identifiers for species that are already defined, including: National Center for Biotechnology Information(NCBI) employs a numeric 'taxid' or Taxonomy identifier, a "stable unique identifier", e.g., the taxid of Homo sapiens is 9606. Kyoto Encyclopedia of Genes and Genomes(KEGG) employs a three- or four-letter code for a limited number of organisms; in this code, for example, H. sapiens is simply hsa. UniProt employs an "organism mnemonic" of not more than five alphanumeric characters, e.g., HUMAN for H. sapiens. Integrated Taxonomic Information System(ITIS) provides a unique number for each species. The LSID for Homo sapiens is urn:lsid:catalogueoflife.org:taxon:4da6736d-d35f-11e6-9d3f-bc764e092680:col20170225. --Lumping and splitting-- The naming of a particular species, including which genus(and higher taxa) it is placed in, is a hypothesis about the evolutionary relationships and distinguishability of that group of organisms. As further information comes to hand, the hypothesis may be corroborated or refuted. Sometimes, especially in the past when communication was more difficult, taxonomists working in isolation have given two distinct names to individual organisms later identified as the same species. When two species names are discovered to apply to the same species, the older species name is given priority and usually retained, and the newer name considered as a junior synonym, a process called synonymy. Dividing a taxon into multiple, often new, taxa is called splitting. Taxonomists are often referred to as "lumpers" or "splitters" by their colleagues, depending on their personal approach to recognising differences or commonalities between organisms. The circumscription of taxa, considered a taxonomic decision at the discretion of cognizant specialists, is not governed by the Codes of Zoological or Botanical Nomenclature, in contrast to the PhyloCode, and contrary to what is done in several other fields, in which the definitions of technical terms, like geochronological units and geopolitical entities, are explicitly delimited. --Broad and narrow senses-- The nomenclatural codes that guide the naming of species, including the ICZN for animals and the ICN for plants, do not make rules for defining the boundaries of the species. Research can change the boundaries, also known as circumscription, based on new evidence. Species may then need to be distinguished by the boundary definitions used, and in such cases the names may be qualified with sensu stricto("in the narrow sense") to denote usage in the exact meaning given by an author such as the person who named the species, while the antonym sensu lato("in the broad sense") denotes a wider usage, for instance including other subspecies. Other abbreviations such as "auct. "("author"), and qualifiers such as "non"("not") may be used to further clarify the sense in which the specified authors delineated or described the species. -Change- Species are subject to change, whether by evolving into new species, exchanging genes with other species, merging with other species or by becoming extinct. --Speciation-- The evolutionary process by which biological populations of sexually-reproducing organisms evolve to become distinct or reproductively isolated as species is called speciation. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book The Origin of Species. Speciation depends on a measure of reproductive isolation, a reduced gene flow. This occurs most easily in allopatric speciation, where populations are separated geographically and can diverge gradually as mutations accumulate. Reproductive isolation is threatened by hybridisation, but this can be selected against once a pair of populations have incompatible alleles of the same gene, as described in the Bateson–Dobzhansky–Muller model. A different mechanism, phyletic speciation, involves one lineage gradually changing over time into a new and distinct form(a chronospecies), without increasing the number of resultant species. --Exchange of genes between species-- Horizontal gene transfer between organisms of different species, either through hybridisation, antigenic shift, or reassortment, is sometimes an important source of genetic variation. Viruses can transfer genes between species. Bacteria can exchange plasmids with bacteria of other species, including some apparently distantly related ones in different phylogenetic domains, making analysis of their relationships difficult, and weakening the concept of a bacterial species. Louis-Marie Bobay and Howard Ochman suggest, based on analysis of the genomes of many types of bacteria, that they can often be grouped "into communities that regularly swap genes", in much the same way that plants and animals can be grouped into reproductively isolated breeding populations. Bacteria may thus form species, analogous to Mayr's biological species concept, consisting of asexually reproducing populations that exchange genes by homologous recombination. --Extinction-- A species is extinct when the last individual of that species dies, but it may be functionally extinct well before that moment. It is estimated that over 99 percent of all species that ever lived on Earth, some five billion species, are now extinct. Some of these were in mass extinctions such as those at the ends of the Ordovician, Devonian, Permian, Triassic and Cretaceous periods. Mass extinctions had a variety of causes including volcanic activity, climate change, and changes in oceanic and atmospheric chemistry, and they in turn had major effects on Earth's ecology, atmosphere, land surface and waters. Another form of extinction is through the assimilation of one species by another through hybridization. The resulting single species has been termed as a "compilospecies". -Practical implications- Biologists and conservationists need to categorise and identify organisms in the course of their work. Difficulty assigning organisms reliably to a species constitutes a threat to the validity of research results, for example making measurements of how abundant a species is in an ecosystem moot. Surveys using a phylogenetic species concept reported 48% more species and accordingly smaller populations and ranges than those using nonphylogenetic concepts; this was termed "taxonomic inflation", which could cause a false appearance of change to the number of endangered species and consequent political and practical difficulties. Some observers claim that there is an inherent conflict between the desire to understand the processes of speciation and the need to identify and to categorise. Conservation laws in many countries make special provisions to prevent species from going extinct. Hybridization zones between two species, one that is protected and one that is not, have sometimes led to conflicts between lawmakers, land owners and conservationists. One of the classic cases in North America is that of the protected northern spotted owl which hybridises with the unprotected California spotted owl and the barred owl; this has led to legal debates. It has been argued, that since species are not comparable, simply counting them is not a valid measure of biodiversity; alternative measures of phylogenetic biodiversity have been proposed. -History- --Classical forms-- In his biology, Aristotle used the term γένος(génos) to mean a kind, such as a bird or fish, and εἶδος(eidos) to mean a specific form within a kind, such as(within the birds) the crane, eagle, crow, or sparrow. These terms were translated into Latin as "genus" and "species", though they do not correspond to the Linnean terms thus named; today the birds are a class, the cranes are a family, and the crows a genus. A kind was distinguished by its attributes; for instance, a bird has feathers, a beak, wings, a hard-shelled egg, and warm blood. A form was distinguished by being shared by all its members, the young inheriting any variations they might have from their parents. Aristotle believed all kinds and forms to be distinct and unchanging. More importantly, in Aristotle's works, the terms γένος(génos) and εἶδος(eidos) are relative; a taxon that is considered an eidos in a given context can be considered a génos in another, and be further subdivided into eide(plural of eidos). His approach remained influential until the Renaissance, and still, to a lower extent, today. --Fixed species-- When observers in the Early Modern period began to develop systems of organization for living things, they placed each kind of animal or plant into a context. Many of these early delineation schemes would now be considered whimsical: schemes included consanguinity based on colour(all plants with yellow flowers) or behaviour(snakes, scorpions and certain biting ants). John Ray, an English naturalist, was the first to attempt a biological definition of species in 1686, as follows: No surer criterion for determining species has occurred to me than the distinguishing features that perpetuate themselves in propagation from seed. Thus, no matter what variations occur in the individuals or the species, if they spring from the seed of one and the same plant, they are accidental variations and not such as to distinguish a species... Animals likewise that differ specifically preserve their distinct species permanently; one species never springs from the seed of another nor vice versa. In the 18th century, the Swedish scientist Carl Linnaeus classified organisms according to shared physical characteristics, and not simply based upon differences. Like many contemporary systematists, he established the idea of a taxonomic hierarchy of classification based upon observable characteristics and intended to reflect natural relationships. At the time, however, it was still widely believed that there was no organic connection between species(except, possibly, between those of a given genus), no matter how similar they appeared. This view was influenced by European scholarly and religious education, which held that the taxa had been created by God, forming an Aristotelian hierarchy, the scala naturae or great chain of being. However, whether or not it was supposed to be fixed, the scala(a ladder) inherently implied the possibility of climbing. --Mutability-- In viewing evidence of hybridisation, Linnaeus recognised that species were not fixed and could change; he did not consider that new species could emerge and maintained a view of divinely fixed species that may alter through processes of hybridisation or acclimatisation. By the 19th century, naturalists understood that species could change form over time, and that the history of the planet provided enough time for major changes. Jean-Baptiste Lamarck, in his 1809 Zoological Philosophy, described the transmutation of species, proposing that a species could change over time, in a radical departure from Aristotelian thinking. In 1859, Charles Darwin and Alfred Russel Wallace provided a compelling account of evolution and the formation of new species. Darwin argued that it was populations that evolved, not individuals, by natural selection from naturally occurring variation among individuals. This required a new definition of species. Darwin concluded that species are what they appear to be: ideas, provisionally useful for naming groups of interacting individuals, writing: I look at the term species as one arbitrarily given for the sake of convenience to a set of individuals closely resembling each other... It does not essentially differ from the word variety, which is given to less distinct and more fluctuating forms. The term variety, again, in comparison with mere individual differences, is also applied arbitrarily, and for convenience sake. Botany, also called plant science, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists(in the strict sense) study approximately 410,000 species of land plants, including some 391,000 species of vascular plants(of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – plants that were edible, poisonous, and possibly medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to monasteries, contained plants possibly having medicinal benefit. They were forerunners of the first botanical gardens attached to universities, founded from the 1540s onwards. One of the earliest was the Padua botanical garden. These gardens facilitated the academic study of plants. Efforts to catalogue and describe their collections were the beginnings of plant taxonomy and led in 1753 to the binomial system of nomenclature of Carl Linnaeus that remains in use to this day for the naming of all biological species. In the 19th and 20th centuries, new techniques were developed for the study of plants, including methods of optical microscopy and live cell imaging, electron microscopy, analysis of chromosome number, plant chemistry and the structure and function of enzymes and other proteins. In the last two decades of the 20th century, botanists exploited the techniques of molecular genetic analysis, including genomics and proteomics and DNA sequences to classify plants more accurately. Modern botany is a broad subject with contributions and insights from most other areas of science and technology. Research topics include the study of plant structure, growth and differentiation, reproduction, biochemistry and primary metabolism, chemical products, development, diseases, evolutionary relationships, systematics, and plant taxonomy. Dominant themes in 21st-century plant science are molecular genetics and epigenetics, which study the mechanisms and control of gene expression during differentiation of plant cells and tissues. Botanical research has diverse applications in providing staple foods, materials such as timber, oil, rubber, fibre and drugs, in modern horticulture, agriculture and forestry, plant propagation, breeding and genetic modification, in the synthesis of chemicals and raw materials for construction and energy production, in environmental management, and the maintenance of biodiversity. -Etymology- The term "botany" comes from the Ancient Greek word botanē(βοτάνη) meaning "pasture", "herbs" "grass", or "fodder"; Botanē is in turn derived from boskein(Greek: βόσκειν), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. -History- --Early botany-- Botany originated as herbalism, the study and use of plants for their possible medicinal properties. The early recorded history of botany includes many ancient writings and plant classifications. Examples of early botanical works have been found in ancient texts from India dating back to before 1100 BCE, Ancient Egypt, in archaic Avestan writings, and in works from China purportedly from before 221 BCE. Modern botany traces its roots back to Ancient Greece specifically to Theophrastus(c. 371–287 BCE), a student of Aristotle who invented and described many of its principles and is widely regarded in the scientific community as the "Father of Botany". His major works, Enquiry into Plants and On the Causes of Plants, constitute the most important contributions to botanical science until the Middle Ages, almost seventeen centuries later. Another work from Ancient Greece that made an early impact on botany is De materia medica, a five-volume encyclopedia about preliminary herbal medicine written in the middle of the first century by Greek physician and pharmacologist Pedanius Dioscorides. De materia medica was widely read for more than 1,500 years. Important contributions from the medieval Muslim world include Ibn Wahshiyya's Nabatean Agriculture, Abū Ḥanīfa Dīnawarī's(828–896) the Book of Plants, and Ibn Bassal's The Classification of Soils. In the early 13th century, Abu al-Abbas al-Nabati, and Ibn al-Baitar(d. 1248) wrote on botany in a systematic and scientific manner. In the mid-16th century, botanical gardens were founded in a number of Italian universities. The Padua botanical garden in 1545 is usually considered to be the first which is still in its original location. These gardens continued the practical value of earlier "physic gardens", often associated with monasteries, in which plants were cultivated for suspected medicinal uses. They supported the growth of botany as an academic subject.
