On 15 January 1966, Nigeria’s First Republic ended abruptly in a violent military coup that shocked the nation. Senior political leaders and key military officers were killed in coordinated attacks across the country. The coup did not immediately grant power to those who initiated it. Instead, Major‑General Johnson Aguiyi‑Ironsi, the army’s most senior surviving officer, assumed control and became Head of the Federal Military Government on 16 January 1966. This event transformed Nigeria’s political landscape and ushered in decades of military involvement in governance.
Political Leaders Assassinated
Sir Abubakar Tafawa Balewa
Sir Abubakar Tafawa Balewa was Nigeria’s Prime Minister and the head of its civilian government under the First Republic. On 15 January 1966, he was arrested and killed by coup plotters in Lagos. His body was found after the coup and returned home for burial. His death marked the end of constitutional civilian rule in Nigeria.
Sir Ahmadu Bello
Sir Ahmadu Bello was the Premier of the Northern Region and a leading political figure whose influence extended across the north. He was assassinated in Kaduna during the coup, along with his senior wife. Bello had been a central figure in national politics, and his death removed a stabilising leader in Nigeria’s most populous region.
Samuel Ladoke Akintola
Chief Samuel Ladoke Akintola was the Premier of the Western Region when the coup occurred. Akintola was killed in Ibadan. His assassination eliminated another key regional leader and deepened the political crisis.

Assumption of Power and Immediate Aftermath
The January 1966 coup did not succeed in all parts of the country, and the plotters failed to seize full control. In the vacuum that followed, Major‑General Johnson Aguiyi‑Ironsi, the most senior military officer who was not assassinated, assumed power as Head of the Federal Military Government on 16 January 1966. Under his leadership, the military formally took over governance, ending the First Republic.
Ironsi’s regime attempted to restore national unity and order, but ethnic and regional suspicions persisted. The fact that most of those killed were political leaders from the Northern and Western Regions contributed to fears of regional targeting, and these tensions played a role in subsequent events, including the July 1966 counter‑coup and escalating ethnic violence.
Legacy of the January 1966 Coup
The deaths on 15 January 1966 did more than end civilian rule; they reshaped Nigerian politics for years to come. The elimination of top political leadership and senior military officers disrupted governance and created mistrust across regional lines. The coup and its aftermath are widely regarded as key factors contributing to Nigeria’s political instability in the 1960s, including the conditions that led to the Nigerian Civil War (1967–1970).
