On January 15, 1966, Nigeria’s First Republic was violently toppled by a group of young army majors in what became the country’s first military coup. The coup detonated long‑standing regional and ethnic tensions and set the stage for one of the most consequential moments in Nigerian history. It led to the rise of Major‑General Johnson Thomas Umunnakwe Aguiyi‑Ironsi as Head of State, the tragic death of Brigadier Zakariya Maimalari, and ultimately a brutal Northern‑led counter‑coup that reshaped the nation’s political landscape.
Who Was Aguiyi‑Ironsi?
Major‑General Johnson Aguiyi‑Ironsi was a career Nigerian army officer who became the first Nigerian General Officer Commanding (GOC) in February 1965 after the British commander handed over leadership of the army. When the January coup erupted, Ironsi, though not part of the original conspiracy, acted decisively to suppress the uprising and restore order. With the civilian government paralyzed, he assumed power on January 16, 1966, positioning himself as the head of the new Federal Military Government.

Despite his efforts to stabilize the country, suspicions about his intentions spread rapidly. Many Nigerians, especially in the North and West, believed the January coup was an “Igbo coup,” partly because most of the key victims were northern politicians and officers and because Aguiyi‑Ironsi was Igbo and became Head of State.
Brigadier Zakariya Maimalari: A Northern Loss
Brigadier Zakariya Maimalari was one of the most senior Northern officers in the Nigerian Army. During the January 1966 coup, he was killed under chaotic circumstances while being confronted by one of the coup plotters, which many in the North believed was part of a targeted attack on northern military leadership. His murder exacerbated resentment among Northern soldiers and became a rallying point for revenge.
Aguiyi‑Ironsi’s Hard Choices and Controversial Policies
Once in power, Ironsi sought to unify the country under military rule. Among his most controversial moves was Decree No. 34, promulgated in May 1966, which abolished Nigeria’s federal system and replaced it with a unitary state. This was intended to reduce ethnic divisions but instead alarmed many Northern leaders who felt it threatened regional autonomy and would disadvantage Northern civil servants.
Compounding tensions, Ironsi did not prosecute the January coup plotters in a public military tribunal. Although the conspirators were detained, their lack of formal punishment was widely criticized as leniency and further fueled Northern suspicions.
The Northern Counter‑Coup of July 1966
Anger over the January coup’s casualties and policies like Decree No. 34 eventually culminated in a coordinated backlash. On July 28–29, 1966, Northern soldiers, led by officers including Lt.‑Colonel Murtala Muhammed, staged a counter‑coup. Their primary grievances were revenge for their fallen colleagues and opposition to Ironsi’s centralizing agenda.
During this counter‑coup, Ironsi and his host, Lt.‑Colonel Adekunle Fajuyi, were assassinated in Ibadan. The coup leaders then appointed Lt.‑Colonel (later General) Yakubu Gowon as Head of State, reinstating Northern dominance in the military hierarchy.
Aftermath: Violence and the Path to Civil War
The July counter‑coup did not simply lead to a change in leadership; it unleashed widespread violence against Igbo soldiers and civilians, especially in the Northern region. These attacks, now referred to as the 1966 anti‑Igbo pogroms, marked one of the darkest chapters in Nigeria’s history and helped precipitate the eventual secession of the Eastern Region as Biafra in 1967.

Legacy: Lessons from 1966
The events of 1966 underscore how quickly political and ethnic tensions can escalate in a diverse nation. Ironsi’s attempts to forge unity inadvertently heightened mistrust, while the deaths of leaders like Maimalari became potent symbols of grievance. The Northern counter‑coup reshaped Nigeria’s military and political order and contributed directly to the civil war that followed.
These moments are not just historical footnotes they are among the defining forces that have influenced Nigeria’s subsequent military and civilian governance struggles. Today, their lessons remain deeply relevant for understanding the challenges of national unity, civil‑military relations, and federalism in contemporary Nigeria.
