His administration sought to unify Nigeria under a centralised system, but his policies sparked ethnic tensions. Aguiyi-Ironsi’s rule ended abruptly on July 29, 1966 when he was assassinated during a counter-coup.
Gen. Yakubu Gowon GCFR, longest serving military leader
Gen. Yakubu Gowon rose to power on August 1, 1966 after the counter-coup that ousted Aguiyi-Ironsi.
His tenure, which lasted until July 29, 1975, was marked by the Nigerian Civil War (1967–1970) and post-war reconstruction.
Gowon’s government promoted national unity and development, but his prolonged rule eventually led to dissatisfaction within the military ranks, culminating in his removal via a bloodless coup.
Gen. Murtala R. Mohammad
Gen. Murtala R. Mohammad assumed leadership on July 29, 1975 after the coup that removed Gowon.
Known for his bold reforms and anti-corruption stance, Murtala initiated sweeping changes in the civil service and governance. His tenure was tragically cut short when he was assassinated on February 13, 1976 during an attempted coup, just over six months into his rule.
Gen. Olusegun Obasanjo
Following Murtala’s assassination, Gen. Olusegun Obasanjo took over as head of state on February 13, 1976.
He continued Murtala’s reform agenda and played a role in preparing Nigeria for a return to civilian rule.
Obasanjo handed over power to a democratically elected government on October 1, 1979, becoming the first military leader in Nigeria to voluntarily relinquish power.

Maj. Gen. Muhammadu Buhari
Maj. Gen. Muhammadu Buhari emerged as head of state on December 31, 1983 after a coup that toppled the civilian government of President Shehu Shagari.
Buhari’s regime focused on anti-corruption and discipline, introducing the War Against Indiscipline (WAI) campaign. His strict policies and authoritarian style led to his removal by another military coup on August 27, 1985.
Gen. Ibrahim B. Babangida GCFR
Gen. Ibrahim B. Babangida seized power on August 27, 1985, following the ousting of Buhari. His administration introduced the Structural Adjustment Programme (SAP), aimed at reviving Nigeria’s economy through liberalisation and deregulation.
Babangida’s rule lasted until August 26, 1993, ending in controversy after the annulment of the June 12, 1993 presidential election.
Gen. Sani Abacha GCON
Gen. Sani Abacha took control on November 17, 1993 after a palace coup that removed the interim government of Ernest Shonekan.
His regime, according to researchers, was characterised by authoritarianism, human rights abuses, and tight economic control.
Despite international condemnation, Abacha maintained a firm grip on power until his sudden death on June 8, 1998.
Gen. Abdulsalami Abubakar GCFR
Gen. Abdulsalami Abubakar assumed office on June 8, 1998 following Abacha’s death. He is credited with overseeing Nigeria’s transition to democracy, culminating in the handover to a civilian government on May 29, 1999.
Abubakar’s brief tenure was marked by constitutional reforms and preparations for democratic elections, effectively ending military rule in Nigeria.
