What system was set up in South Africa in 1948? What did it do?

Apartheid a word meaning "separateness", or "the state of being apart", literally was a system of racial segregation in South Africa enforced through legislation by the National Party (NP), the governing party from 1948 to 1994. Under apartheid, the rights, associations, and movements of the majority black inhabitants and other ethnic groups were curtailed, and white minority rule was maintained. Apartheid was developed after World War II by the Afrikaner-dominated National Party and Broederbond organisations. The ideology was also enforced in South West Africa, which was administered by South Africa under a League of Nations mandate (revoked in 1966 via United Nations Resolution 2145), until it gained independence as Namibia in 1990. By extension, the term is currently used for forms of systematic segregation established by the state authority in a country against the social and civil rights of a certain group of citizens due to ethnic prejudices
