Nelson Mandela was born in 1918 in South Africa and orphaned at age 9. He became involved in political activism through the African National Congress in 1943. Mandela went underground in 1961 to lead the ANC's armed wing against apartheid and was arrested in 1962. He was sentenced to life imprisonment and incarcerated for 27 years, during which he earned a law degree. Mandela was released in 1990 and elected president of South Africa in 1994, becoming the country's first black head of state in a fully democratic election. He died in 2013 at age 95 after helping transform South Africa into a multi-racial democracy.
