On June 12, 1964, Nelson Mandela, along with numerous political detainees, was sentenced to life imprisonment in what remains the most sensational treason trial in the history of South Africa. The incarceration of Mandela and other political prisoners on Robben Island would become a symbol of the struggle to end apartheid and win freedom for the black majority in South Africa. On February 2, 1990, President F.W. De Klerk stood before Parliament and announced the legalization of the African National Congress and a host of other banned political organizations. At the same time, he announced that Nelson Mandela, having served twenty-seven years in prison, would be released within seven days.
