Nelson Mandela was born in 1918 in South Africa and grew up under apartheid, where black people were segregated and had few rights. He joined the African National Congress in 1944 to fight against apartheid through protests and was imprisoned for 27 years for his leadership. After his release in 1990, he became president of the ANC and helped end apartheid, becoming South Africa's first black president in 1994 after apartheid was abolished. He worked to promote reconciliation and equal rights in South Africa.
