In the years following his military career, Olusegun Obasanjo received the Indira Gandhi Peace Prize, a recognition that placed him among a select group of international figures honored for contributions to peace and development — a fitting marker for a life spent at the intersection of soldiering and statecraft.

Born on 5 March 1937 in Abeokuta, Nigeria, Obasanjo — whose full name is Chief Olusegun Matthew Okikiola Ogunboye Aremu Obasanjo — attended Baptist Boys' High School before pursuing a military education that took him across several institutions. His training included Mons Officer Cadet School, the Defence Services Staff College, and the Royal College of Defence Studies, a sequence that shaped him into a career military officer. He holds Nigerian citizenship and has worked across the fields of the military, politics, and engineering.

His languages reflect the breadth of his engagement with Nigeria and its peoples. Obasanjo communicates in English, Yoruba, Hausa, and Nigerian Pidgin, a range that speaks to the diversity of the country in which he has spent his public life. His international standing brought him a number of honors from foreign governments and institutions, among them the Order of the Star of Ghana, the Order of the Pioneers of Liberia, the Grand Cross with Chain of the Order of Merit of the Republic of Hungary, and honorary doctorates from Peking University and the Peoples' Friendship University of Russia. Within Nigeria, he holds both the Order of the Federal Republic and the Order of Nigeria.

He is also an honorary fellow of the African Academy of Sciences. That fellowship, alongside the accumulation of decorations from institutions across Africa, Europe, and Asia, offers a concrete measure of how his career as a Nigerian politician and military figure was received beyond the borders of his country. His name appears in the Library of Congress Name Authority File as Obasanjo, Olusegun.
