Olusegun Obasanjo (born March 5, 1937, Abeokuta, Nigeria) is a Nigerian general, statesman, and diplomat, who was the first military ruler in Africa to hand over power to a civilian government. He served as Nigeria’s military ruler (1976–79) and, as a civilian, as president (1999–2007).

Obasanjo attended Baptist Boys’ High School in Abeokuta, in southwest Nigeria, and later worked as a teacher. Unable to afford college, he joined the army in 1958 and received officer training in England. Obasanjo rose quickly through the army ranks. During the Biafra conflict (1967–70) he was appointed to head a commando division that was stationed at the Biafran front in southeastern Nigeria. The conflict ended when Biafran forces surrendered to him in January 1970.
