The military coup of 15 January 1966 stands as one of the most consequential moments in Nigeria’s post-independence history. Beyond ending the First Republic, the coup reshaped political power, ethnic relations, and national identity. Over time, it came to be widely described as the “Igbo coup”, a label that has endured for decades and continues to influence how the events of 1966 are remembered and debated.
Nigeria on the Edge
By the mid-1960s, Nigeria’s political system was under intense strain. Elections were fiercely contested and widely criticised. Regional rivalries dominated national politics, and the Western Region was gripped by violent political conflict. Allegations of corruption and abuse of power weakened confidence in civilian leadership, while federal institutions struggled to manage growing instability.

Within the armed forces, dissatisfaction was rising. Many junior officers believed that political leaders had failed to govern effectively and that the country was drifting towards chaos. This environment created the conditions in which military intervention appeared, to some officers, as a corrective measure rather than a rebellion.
The January Coup
In the early hours of 15 January 1966, a group of junior officers launched coordinated operations in different parts of the country. Major Chukwuma Kaduna Nzeogwu emerged as a key figure, particularly in Kaduna. Other officers acted in Lagos, Ibadan, and Abeokuta.
The coup achieved mixed results. It succeeded in Kaduna, where control was quickly established, but failed in Lagos, the political and military centre of Nigeria. Poor coordination, limited support across units, and resistance from loyalist forces prevented the coup from consolidating power nationwide. The failure in Lagos proved decisive.
Killings and Public Reaction
Among those killed during the coup were Prime Minister Abubakar Tafawa Balewa, Northern Premier Ahmadu Bello, and Western Premier Samuel Ladoke Akintola. Several senior military officers, mainly from the North, were also killed. No prominent Eastern political leader died during the operation. President Nnamdi Azikiwe was abroad at the time.
This pattern of casualties had a profound impact on public perception. In many parts of Northern Nigeria, the absence of Eastern victims was interpreted as evidence of ethnic targeting. The belief spread that the coup was designed to eliminate political rivals while favouring the Igbo.
At the same time, the uneven outcome reflected the fragmented nature of the operation. Several intended targets survived because they were absent, resisted arrest, or were protected by loyal troops. The pattern of deaths, however, became central to how the coup was remembered.
Military Rule and Decree No. 34
With civilian authority effectively collapsed, Major General Johnson Aguiyi Ironsi assumed power as Head of State. As the most senior officer in command, he moved quickly to stabilise the country and restore order.
In May 1966, Ironsi introduced Decree No. 34, which replaced Nigeria’s federal system with a unitary structure. The decision was deeply controversial. In the North, it was widely viewed as an attempt to concentrate power at the centre and weaken regional autonomy. Combined with the memory of January’s events, the decree intensified fears of political domination.
From Fear to Retaliation
Tensions continued to rise in the months that followed. Rumours circulated, grievances deepened, and ethnic suspicion hardened. In July 1966, Northern officers carried out a countercoup. Ironsi was killed, along with several senior officers.
The violence that followed extended beyond the military. Igbo soldiers and civilians were attacked in Northern cities, leading to widespread killings and mass displacement. What began as a political crisis had now escalated into ethnic violence, fundamentally altering Nigeria’s social fabric.
The Making of a Label
The term “Igbo coup” gained lasting influence because it offered a clear and emotionally powerful explanation for a period of chaos and loss. The ethnic identity of many coup plotters, the pattern of assassinations, and subsequent political decisions all reinforced the narrative.
As the country moved closer to civil war, the label became embedded in public discourse. It shaped how later events were understood, how blame was assigned, and how communities interpreted their own suffering.

A Legacy That Endures
The debate surrounding the January 1966 coup remains unresolved because it touches on deeper questions of power, trust, and belonging. The events of that year transformed Nigeria’s politics and exposed the dangers of unresolved regional and ethnic divisions.
The legacy of the coup lies not only in the collapse of civilian rule, but in how fear and suspicion turned a failed military intervention into a national tragedy.
Author’s Note
The story of the January 1966 coup is central to understanding Nigeria’s modern history because it reveals how political breakdown, fear, and contested narratives can reshape a nation. The enduring controversy surrounding the “Igbo coup” label reflects the lasting impact of mistrust and unresolved grievances. The key lesson is that when unity weakens and perceptions harden, national crises can leave wounds that take generations to heal.
