A South African citizen from a Jewish-Lithuanian family, Slovo was a delegate to the multiracial Congress of the People of June 1955 which drew up the Freedom Charter. He was imprisoned for six months in 1960, and emerged as a leader of Umkhonto we Sizwe the following year. He lived in exile from 1963 to 1990, conducting operations against the apartheid régime from the United Kingdom, Angola, Mozambique, and Zambia. In 1990 he returned to South Africa, and took part in the negotiations that ended apartheid. He became known for proposing the "sunset clauses" covering the 5 years following a democratic election, including guarantees and concessions to all sides, and his fierce non-racialist stance. After the elections of 1994, he became Minister for Housing in Nelson Mandela's government. He died of cancer in 1995.
