What is apartheid and what are two examples of it in South Africa's history.

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. Contact between the two groups would be limited. Despite strong and consistent opposition to apartheid within and outside of South Africa, its laws remained in effect for the better part of 50 years. In 1991, the government of President F.W. de Klerk began to repeal most of the legislation that provided the basis for apartheid. President de Klerk and activist Nelson Mandela would later win the Nobel Peace Prize for their work creating a new constitution for South Africa.
