This study traces the evolution of the anti-apartheid movement from its origins in the 1940s through the civil rights and black power eras to its maturation in the 1980s as a force that transformed U.S. foreign policy. The movement initially met resistance and was soon repressed, only to re-emerge during the civil rights era, when it became radicalized with the coming of the black freedom movement. The book looks at three important political groups: TransAfrica the black lobby for Africa and the Caribbean; the Free South Africa Movement; and lastly the Congressional Black Caucus and its role in passing sanctions against South Africa over President Reagan’s veto. It concludes with an assessment of the impact of sanctions on the release of Nelson Mandela and his eventual election as president of South Africa.
