Prior to the mid-twentieth century, Cape Town was one of the most racially integrated cities in the South Africa. In the 1948 national elections, the National Party won on a platform of "apartheid" (racial segregation) under the slogan of "swart gevaar" (Afrikaans for "black danger"). This led to the erosion and eventual abolition of the Cape's multiracial franchise, as well as to the Group Areas Act, which classified all areas according to race. Formerly multi-racial suburbs of Cape Town were either purged of residents deemed unlawful by apartheid legislation or demolished. The most infamous example of this in Cape Town was District Six. After it was declared a whites-only region in 1965, all housing there was demolished and over 60,000 residents were forcibly removed. Many of these residents were relocated to the Cape Flats. Under apartheid, the Cape was considered a "Coloured labour preference area", to the exclusion of "Bantus", i.e. Africans. The implementation of this policy was widely opposed by trade unions, civil society and opposition parties. It is notable that this policy was not advocated for by any coloured political group, and its implementation was a unilateral decision by the apartheid government.
