Explanation:

Apartheid (“apartness” in the language of Afrikaans) was a system of legislation that upheld segregationist policies against non-white citizens of South Africa. After the National Party gained power in South Africa in 1948, its all-white government immediately began enforcing existing policies of racial segregation. Under apartheid, nonwhite South Africans (a majority of the population) would be forced to live in separate areas from whites and use separate public facilities.
