On January 15, 1966, Nigeria witnessed its first military coup, ending the young country’s parliamentary democracy and setting in motion decades of political upheaval. The event remains a defining moment in Nigerian history, shaping perceptions of governance, ethnicity, and military intervention.
The First Republic in Crisis
By the mid‑1960s, Nigeria’s First Republic was under severe strain. Political parties and regional governments battled for power, and electoral violence, particularly in the Western Region, had undermined confidence in democracy. Operation Wetie and other violent clashes signalled the fragility of civilian governance.

The army, especially junior officers, grew frustrated with political corruption, weak institutions, and regional tensions. This environment set the stage for drastic action.
The Coup Unfolds
In the early hours of January 15, 1966, coordinated detachments of mostly junior army officers attacked key cities, including Kaduna, Lagos, and Ibadan. The coup targeted top political leaders:
- Prime Minister Sir Abubakar Tafawa Balewa
- Sir Ahmadu Bello, Premier of the Northern Region
- Chief Samuel Ladoke Akintola, Premier of the Western Region
- Chief Festus Okotie‑Eboh, Federal Minister
Several senior army officers were also killed, including:
- Brigadier Samuel Ademulegun
- Brigadier Zakariya Maimalari
- Lieutenant-Colonel James Yakubu Gyang Pam
The deaths created a leadership vacuum, paralyzing the nation and its military command.
Motives of the Plotters
The coup plotters claimed their action aimed to end political corruption and mismanagement. While most participants were from the Eastern Region, the plan was political and institutional, not a formal ethnic agenda. Historians agree that the coup’s primary aim was reform and stabilization rather than ethnic domination.
Aftermath: Rise of Aguiyi-Ironsi
Following the coup, Major-General Johnson Aguiyi-Ironsi assumed power on January 16, 1966. He suspended the constitution, dissolved political parties, and established military rule, ending the First Republic.
Although Ironsi’s administration sought stability, suspicions grew, especially in the Northern Region, where the deaths of many leaders created perceptions of bias, contributing to regional and ethnic mistrust.

From Coup to Counter-Coup
The mistrust following January’s coup fueled the July 29, 1966 counter-coup, during which Ironsi and Colonel Francis Fajuyi were assassinated. Lieutenant-Colonel Yakubu Gowon became Head of State. The counter-coup deepened ethnic tensions, leading to reprisals against Eastern Nigerians in the North and ultimately to the Nigerian Civil War (1967–1970).
Legacy of January 1966
The coup:
- Ended Nigeria’s First Republic and replaced civilian governance with military rule
- Intensified ethnic and regional suspicion
- Established patterns of governance by decree
These events had lasting impacts on Nigeria’s political stability and national cohesion, shaping challenges that continue today.
Author’s Note
January 15, 1966, was Nigeria’s first military intervention in civilian politics, a moment that continues to spark debate over whether it was a coup or a revolution. Based on historical evidence, it was unequivocally a coup: a sudden seizure of government by a small group of military officers without mass civilian involvement, popular mandate, or ideological revolution. While some framed it as a revolutionary attempt to cleanse corruption and restore order, the reality shows that the action was primarily military and political, not a popular uprising or systemic social revolution. The event, however, had revolutionary consequences for Nigeria, reshaping its governance, intensifying ethnic tensions, and altering the nation’s trajectory outcomes that still echo today.
