Answer:
White supremacy in South Africa had its beginning in the initial Dutch colonial settlement of the Cape. The first Dutch settlers brought with them a vision of colonialism in which Europeans were superior to non‐Europeans and could behave in colonies in ways that were not tolerated at home. The colonial idea of racial slavery corrupted early Cape officials before there were any slaves, and made the introduction of slavery inevitable. Marriages between white men and non‐European women were tolerated at the Cape as elsewhere in the Dutch colonial realm, but racially mixed couples were not welcome in the Netherlands. The racial exclusivity of the Dutch home community gained ground at the Cape as its European settlers began to see themselves as a home community away from home, and sought to emulate home standards in so far as this was practicable in an overseas colonial setting.
White citizens of the Union of South Africa will decide at the polls on April 16 whether or not to renew the mandate of the Nationalist Party for another five years. The Nationalists, who have been in power for a decade, are the leading apostles of South Africa's policy of apartheid, which is designed to assure white supremacy through complete segregation of whites and non-whites. Non-whites comprise four-fifths of the country's population, but they are denied the franchise in three of the four provinces.
