Origin: 1940: Afrikaans, literally ‘separateness,’ from Dutch apart ‘separate’ + -heid (equivalent of -hood).
Oxford Encyclopedia of Women in World History:
Apartheid” refers to the system of racial domination and rule through which a white minority led by the Afrikaner National Party government oppressed and exploited the vast majority of black South Africans. Apartheid law decreed that the country's population be divided into four race groups: white (descendants of European settlers), African (indigenous groups), “coloured” (mixed race), and Indian (mainly descendants of indentured laborers brought by the British from India).
Brewer's Dictionary of Phrase and Fable:
A policy adopted by the Afrikaner National Party in 1948 to ensure the dominance of the white minority. It divided South Africa into separate areas for whites, ‘Coloureds’ and blacks, causing the country's withdrawal from the British Commonwealth in 1961 and leading to rioting, repression and isolation from other nations. Limited constitutional rights were granted to non-whites in 1985, and the remaining apartheid laws were repealed in 1991.
