1959, the south African government promulgated the Bantu autonomy law, which planned to assemble 632 tribal autonomous institutions into eight Toustain autonomous regions according to their ethnic groups (later increased to 10), and set up a legislative assembly and an autonomous government controlled by the south African government in the BanToustain autonomous region. The original reservation was renamed Ben Toustain (Black Home). 1964, three unconnected transkei reservations were transformed into Ban Toustain through the legislative procedures stipulated by the South African government, and an autonomous government was established. By 1976, the South African government had established 10 "Ban Toustain" in transkei, Bophuthatswana, KwaZulu, Rabova, Siskai, Gazankulu, Venda, Swaziland, Basotokwakwa and South Ndebele, and set up their own autonomous governments. 1970, the South African government passed the Ban Toustain Nationality Rights Act, which made it mandatory that all black South Africans living in white areas must belong to a Ban Toustain and obtain their "nationality", thereby canceling all black South Africans' South African citizenship.

In the late 1970s, the black mass movement in South Africa flourished and put forward the slogan of striving for majority rule. In this situation, the white government accelerated the process of "independence" of Ban Toustain. 1976 10 In June, the South African government declared the independence of Transkei. Later, Bophuthatswana (197765438+February), Wenda (1979 September) and Siskai (198165438+February) declared independence. The remaining six classes in Toustain have been renamed as "dependent black countries", and they will also be declared "independent" and separated. According to the "national" constitution formulated by the South African government, the citizens of Ban Toustain who declared independence will lose their South African citizenship, and the blacks in towns (white areas) belonging to Toustain's "national" from all walks of life will become foreigners, and they will lose all their rights in South Africa.

Toustain, which has declared "independence", is still strictly controlled by the South African government in political, military, judicial and diplomatic aspects. Most parliamentarians are appointed by the South African authorities, and officials are also trained and appointed by them; Most of the budget is provided by South Africa. Bantoustan has narrow and barren land, backward agriculture and weak industry. After independence, the economic and political situation was extremely difficult.
