He was the leader of the movement to end apartheid in South Africa.

In 1961, he was arrested for treason, and although acquitted he was arrested again in 1962 for illegally leaving the country. Convicted and sentenced to five years at Robben Island Prison, he was put on trial again in 1964 on charges of sabotage. In June 1964, he was convicted along with several other ANC leaders and sentenced to life in prison.

In 1989, F.W. de Klerk became South African president and set about dismantling apartheid. De Klerk lifted the ban on the ANC, suspended executions, and in February 1990 ordered the release of Nelson Mandela.

Mandela served 27 years in prison, split between Robben Island, Pollsmoor Prison and Victor Verster Prison.
