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.
Migration to South Africa began in the second half of the 17th century when traders from the Dutch East India Company settled in the Cape and started using slaves from South and southeast Asia (mainly from India but also from present-day Indonesia, Bangladesh, Sri Lanka, and Malaysia) and southeast Africa (Madagascar and Mozambique) as farm laborers and, to a lesser extent, as domestic servants.
