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.
South Africa was colonized by Dutch Europeans and then British. This is why there are white South Africans who speak Afrikaans and English. The other 9 of the official languages are native African languages traditionally spoken by native (Black) Africans. Children are first introduced to their parent's first language. European South Africans have their own accent, however to Americans, it sounds very similar to a British accent.
