Nelson Mandela was born on July 18, 1918, into a royal family of the Xhosa-speaking Thembu tribe in the South African village of Mvezo, where his father, Gadla Henry Mphakanyiswa (c. 1880-1928), served as chief. His mother, Nosekeni Fanny, was the third of Mphakanyiswa’s four wives, who together bore him nine daughters and four sons. After the death of his father in 1927, 9-year-old Mandela—then known by his birth name, Rolihlahla—was adopted by Jongintaba Dalindyebo, a high-ranking Thembu regent who began grooming his young ward for a role within the tribal leadership.
