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 term white race or white people entered the major European languages in the later 17th century, in the context of racialized slavery and unequal status in European colonies. Description of populations as white in reference to their skin color predates this notion and is found in Greco-Roman ethnography and other ancient sources. Scholarship on race generally distinguishes the modern concept from pre-modern descriptions of collective difference.
