What was apartheid and how did it restrict the rights of non-whites?

Apartheid was a system of legal racial segregation that happened in South Africa and South West Africa from 1948 until the early 90s. During Apartheid, Whites where given exclusive treatment. Non-Whites where given harder work, no right to vote, and treated worse than whites. Apartheid was enforced by european colonizers.

After the National Party gained power in South Africa in 1948, its all-white government immediately began enforcing existing policies of racial segregation under a system of legislation that it called apartheid ... de Klerk began to repeal most of the legislation that provided the basis for apartheid.
