with minimal bureaucracy, but were pressured to establish some form of legal framework. Since they were unfamiliar with local customs, the Brooke government created an advisory Supreme Council, mostly consisting of Malay chiefs, to provide guidance. This council is the oldest state legislative assembly in Malaysia, with the first General Council meeting taking place at Bintulu in 1867. In 1928, a Judicial Commissioner, Thomas Stirling Boyd, was appointed as the first legally trained judge. A similar system relating to matters concerning various Chinese communities was also formed. Members of the local community were encouraged by the Brooke regime to focus on particular functions within the territory: the Ibans and other Dayak people were hired as militia while Malays were primarily administrators. Chinese, both local and immigrant, were mostly employed in plantations, mines and as bureaucrats. Expanding trade led to the formation of the Borneo Company Limited in 1856. The company was involved in a wide range of businesses in Sarawak including trade, banking, agriculture, mineral exploration, and development. 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. Charles Anthoni Brooke succeeded his uncle in 1868 as the next White Rajah. Under his rule, Sarawak gained Limbang and the Baram and Trusan valleys from the Sultan of Brunei, later becoming a protectorate in 1888 with Britain handling foreign affairs but the Brooke government retaining administrative powers. Domestically, Brooke established the Sarawak Museum – the oldest museum in Borneo – in 1891, and brokered a peace in Marudi by ending intertribal wars there. Economic development continued, with oil wells drilling from 1910 and the Brooke Dockyard opening two years later. Anthony Brooke, who would become Rajah Muda (heir apparent) in 1939, was born in 1912. A centenary celebration of Brooke rule in Sarawak was held in 1941. During the celebration, a new constitution was introduced that would limit the power of the Rajah and grant the Sarawak people a greater role in the functioning of government. However, this constitution was never fully implemented due to the Japanese occupation. That same year saw the British withdrawing its air and marine forces defending Sarawak
