Fearing defeat, Moshoeshoe made further appeals to High Commissioner Philip Edmond Wodehouse for British assistance. On 12 March 1868, the British Cabinet agreed to place the territory under British protection and the Boers were ordered to leave. In February 1869, the British and the Boers agreed to the Convention of Aliwal North, which defined the boundaries of the protectorate. The arable land west of the Caledon River remained in Boer hands and is referred to as the Lost or Conquered Territory. Moshoeshoe died in 1870 and was buried atop Thaba Bosiu. In 1871 the protectorate was annexed to Cape Colony. The Basotho resisted the British and in 1879 a southern chief, Moorosi, rose in revolt. His campaign was crushed, and he was killed in the fighting. The Basotho then began to fight amongst themselves over the division of Moorosi's lands. The British extended the Cape Peace Preservation Act of 1878 to cover Basutoland and attempted to disarm the natives. Much of the colony rose in revolt in the Gun War (1880-1881), inflicting significant casualties upon the colonial British forces sent to subdue it. A peace treaty of 1881 failed to quell sporadic fighting. Cape Town's inability to control the territory led to its return to crown control in 1884 as the Territory of Basutoland. The colony was bound by the Orange River Colony, Natal Colony, and Cape Colony. It was divided into seven administrative districts: Berea, Leribe, Maseru, Mohale's Hoek, Mafeteng, Qacha's Nek and Quthing. The colony was ruled by the British Resident Commissioner, who worked through the "pitso" (national assembly) of hereditary native chiefs under one paramount chief. Each chief ruled a ward within the territory. The first paramount chief was Lerothodi, the son of Moshoeshoe. During the Second Boer War the colony was neutral. The population grew from around 125,000 in 1875, to 310,000 in 1901, and to 349,000 by 1904. When the Union of South Africa was founded in 1910 the colony was still controlled by the British and moves were made to transfer it to the Union. However the people of Basutoland opposed this and when the National Party put its apartheid policies into place the possibility of annexation was halted. In 1959, a new constitution gave Basutoland its first elected legislature. This was followed in April 1965 with general legislative elections.
