Nelson Mandela 1918-2013 · South Africa
Nelson Rolihlahla Mandela was a South African lawyer, freedom fighter, and statesman. He led the long struggle to end apartheid, the racist system that ruled South Africa from 1948 to 1994. He was born on 18 July 1918 in Mvezo, a small village in the Eastern Cape. He was given the name Rolihlahla, which in Xhosa roughly means 'pulling the branch of a tree' or, informally, 'troublemaker'. A teacher gave him the English name Nelson when he started school. He came from a Thembu royal family. His father died when Nelson was nine, and he was raised at the royal court. He trained as a lawyer in Johannesburg. With his friend Oliver Tambo, he opened the first Black law firm in South Africa in 1952. Black South Africans had almost no rights under apartheid. They could not vote, were forced to live in poor 'townships', and had to carry passes to enter white areas. Mandela joined the African National Congress (ANC) in 1943. He helped lead peaceful campaigns through the 1950s. After the Sharpeville massacre in 1960, when police killed 69 unarmed Black protesters, he changed his mind about non-violence. In 1961 he co-founded Umkhonto we Sizwe (Spear of the Nation), the armed wing of the ANC. He was arrested in 1962 and put on trial for sabotage. In 1964 he was sentenced to life in prison. He served 27 years, mostly on Robben Island. He was released on 11 February 1990. He led the negotiations that ended apartheid. He became South Africa's first democratically elected president in 1994. He died on 5 December 2013, aged 95.
"I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal which I hope to live for and to achieve. But if needs be, it is an ideal for which I am prepared to die."
