Partitioning Under Apartheid
During the apartheid era the country was chopped up into a number of additional pieces which were known as the four TBVC States and the six Non-Independent Homelands. These were created by the apartheid government in order to enforce its policy of racial segregation.
Griqualand East was transferred to Natal Province after the Transkei was declared independent, since it was cut off from the rest of the province. The Transkei (1976) and Ciskei (1981) regions were declared independent of South Africa, after they were formerly part of the Cape Province. (They were re-incorporated into South Africa in 1994, both part of the new Eastern Cape province)
