The history of South Africa is characterised by racial and political violence, territorial conflict, wars of conquest, and inter-ethnic rivalry. The southern African aboriginal Khoi and San lived in the region for millennia. Most of the rest of the population trace their history to later immigration. Africans (also referred to as Bantu) in South Africa are descendants of migrants from central Africa, who first entered southern Africa about 2000 years ago. White South Africans are descendants of later European settlers, mainly from the Netherlands, Germany, France and Britain. The large population of Coloureds, as they were officially classified, are descended at least in part from all of these groups, as well as from slaves imported from Madagascar, East Africa and the then Dutch East Indies.
