original passage: Between 1853 and 1862, there were a number of uprisings against the Brooke government but all were successfully contained with the aid of local tribes. To guard against future uprisings, a series of forts were constructed to protect Kuching, including Fort Margherita, completed in 1871. By that time Brooke's control of Sarawak was such that defences were largely unnecessary.
