The Bantu Homelands Constitution Act enabled the government of South Africa to grant independence to any "Homeland" as determined by the South African apartheid government. It was renamed several times, becoming the Black States Constitution Act, 1971, then the National States Constitution Act, 1971, and finally the Self-governing Territories Constitution Act, 1971. In accordance with this act, independence was eventually granted to Transkei in 1976, Bophuthatswana in 1977, Venda in 1979, and Ciskei in 1981.
