Bechuanaland Protectorate
In the late 19th century, hostilities broke out between the Shona inhabitants of Botswana and Ndebele tribes who were migrating into the territory from the Kalahari Desert. Tensions also escalated with the Boer settlers from the Transvaal. After appeals by the Batswana leaders Khama III, Bathoen and Sebele for assistance, the British Government on 31 March 1885 put "Bechuanaland" under its protection. The northern territory remained under direct administration as the Bechuanaland Protectorate and is today's Botswana, while the southern territory became part of the Cape Colony and is now part of the northwest province of South Africa; the majority of Setswana-speaking people today live in South Africa. The Tati Concessions Land, formerly part of the Matabele kingdom, was administered from the Bechuanaland Protectorate after 1893, to which it was formally annexed in 1911.
When the Union of South Africa was formed in 1910 out of the main British colonies in the region, the Bechuanaland Protectorate, Basutoland (now Lesotho), and Swaziland (the "High Commission Territories") were not included, but provision was made for their later incorporation. However, a vague undertaking was given to consult their inhabitants, and although successive South African governments sought to have the territories transferred, Britain kept delaying, and it never occurred. The election of the National Party government in 1948, which instituted apartheid, and South Africa's withdrawal from the Commonwealth in 1961, ended any prospect of incorporation of the territories into South Africa.
An expansion of British central authority and the evolution of tribal government resulted in the 1920 establishment of two advisory councils representing Africans and Europeans. Proclamations in 1934 regularized tribal rule and powers. A European-African advisory council was formed in 1951, and the 1961 constitution established a consultative legislative council.
