The apartheid era in South Africa lasted more than 40 years. It was marked by political
repression and the attempt to create a homogeneous white South Africa which meant excluding
the non-white majority population. The establishment and maintenance of white supremacy in
South Africa by colonialism and since 1948 grand apartheid was not only the result of racist
regulations and laws but also followed a scientific logic to justify the resettlement and
expulsion of South African blacks.The history of South Africa from 1948 to 1994 can also be
seen as the history of a major society-spanning project an attempt to build a modern state on
the basis of racial segregation. This work investigates the factors that make it possible to
stabilize a policy based on virtually impossible prerequisites over four decades: Ethnic
categorization territorial planning and environmental protection measures.
