Apartheid is a crime against humanity defined in international law as:

inhumane acts . . . committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over any other racial group or groups and committed with the intention of maintaining that regime.

The word itself comes from Afrikaans, and apartheid in South Africa is the best-known example of apartheid in the world. However, that is certainly not the only regime even in modern times which has openly and systematically enforced racial oppression through law. Human Rights Watch and Amnesty International have both recognised Israel as yet another apartheid state. See also: apartheid in Israel.
