Nelson Mandela was born in 1918 in a small South African village. He received a primary education through a mission school and later attended various colleges to study law. In 1943, Mandela joined the African National Congress to campaign for equal treatment of black people in South Africa. He was imprisoned for over 27 years for trying to overthrow the apartheid government. Mandela was released from prison in 1990 and elected as South Africa's first black president in 1994, helping the country transition to a non-racial democracy. After retiring, Mandela continued advocacy and humanitarian work worldwide.
