Apartheid kept a Black majority subordinate by splitting it into separate ethnic homelands, languages, and classifications, so groups distrusted each other instead of uniting against the minority state. Racial categories like 'coloured' were given slightly more privilege than Black South Africans, which made the tiers police each other and kept all of them below whites.
