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.
There were three (or four) phases to the colonisation of South Africa. Initially, colonisation was by an influx of Bantu peoples from the north-east, who took over land prev â¦ iously occupied by the indigenous Khoi and San people. The Bantu moved south until they reached the Kei river.
