The year 1950 saw the introduction of the Population Register act and the Group Areas Act, which were pivotal in the division of space according to race, with the Group Areas Act creating urban spaces for white persons. In the years 1951-1952 the focus shifted to the erasure of black spots from those urban areas, with the Bantu Building Workers Act limiting the areas in which black professionals could practice their trades. The Bantu Authorities Act simultaneously took away the unified black voice by abolishing the Native Representative Council and implementing separation within the black community by creating rural homelands along language and ethnicity. The Native Laws Amendment Act and the Natives (Abolition of Passes and Co-Ordination of Documents) Act further restricted the black man's entry into urban areas.
