Afrikaners are a Southern African ethnic group descended from predominantly Dutch settlers first arriving at the Cape of Good Hope in the 17th and 18th centuries. They traditionally dominated South Africa's politics and commercial agricultural sector prior to 1994. Afrikaans, South Africa's third most widely spoken home language, evolved as the mother tongue of Cape Coloureds. and was taught to colonial settlers by the slaves. It originated from the Dutch vernacular of South Holland, incorporating words brought from the Dutch East Indies and Madagascar by slaves. Afrikaners make up approximately 5.2% of the total South African population based on the number of white South Africans who speak Afrikaans as a first language in the South African National Census of 2011.
