On April 6, 1652 the first white people (Dutch) arrived in South Africa to establish a settlement at the Cape. Their purpose, initially, was not to colonize the area, but to s â¦ upply fresh food for the men on the Dutch ships sailing on the long route between Europe and India.
The Boers were Europeans who settled in southern Africa beginning in the 1600s. Boer means farmer in Dutch, and most Boers were farmers with roots in the Netherlands. The descendants of the Boers are called Afrikaners, a term formerly applied to Boers who were not farmers. Today Afrikaners make up more than half the white population of South Africa.
