Apartheid was a system in South Africa from 1948 to 1994. It takes its name from an Afrikaans word that means "apartness." People were separated on the basis of race. They were divided into four racial groups: black, white, coloured, and Indian. Race was used to decide where people could live. South African whites had access to the best of every public resource. Education, medical care, and other public services provided to black people were not as good as the ones available to whites. , this discrimination was extended to the coloured and Indian residents over the next decades.
