Foreign relations of South Africa during apartheid refers to the foreign relations of South Africa between 1948 and the early 1990s. South Africa introduced apartheid in 1948, as a systematic extension of pre-existing racial discrimination laws. Initially the regime implemented an offensive foreign policy trying to consolidate South African hegemony over Southern Africa. These attempts had clearly failed by the late 1970s. As a result of its racism, occupation of Namibia and foreign interventionism in Angola, the country became increasingly isolated internationally.
