Nelson Mandela is a former President of South Africa, the first to be elected in fully representative democratic elections. Before his presidency, Mandela was an anti-apartheid activist and leader of the African National Congress and its armed wing Umkhonto we Sizwe. He spent 27 years in prison, much of it on Robben Island, on convictions for crimes that included sabotage committed while he spearheaded the struggle against apartheid. —Macmillan Audio
