Nigeria’s history in the 1960s was defined by intense political and ethnic tensions. Less than six years after independence, the country experienced two military coups that reshaped the nation’s governance. The second coup, occurring in July 1966, was led primarily by northern officers who sought to reverse the outcomes of the January coup. The events triggered violence, fear, and speculation about secession, but Nigeria remained a single state. Understanding this period clarifies how the country’s military and political leadership navigated one of its most perilous moments.
Historical Context
The first coup in January 1966 was orchestrated mainly by young officers, predominantly of Igbo origin. It resulted in the assassination of key political and military leaders, particularly from the Northern Region, including Prime Minister Sir Abubakar Tafawa Balewa and Northern Premier Sir Ahmadu Bello. Major General Johnson Aguiyi‑Ironsi assumed power, but his policies, particularly Decree No. 34, which centralised authority and abolished the federal system, heightened northern anxieties about marginalisation. Fear of Igbo dominance within the military and government created fertile ground for a counter-coup later that year.

The July 1966 Counter-Coup
Between 28 and 29 July 1966, northern officers, motivated by revenge and concern for regional influence, staged a counter-coup. The uprising resulted in the assassination of Aguiyi‑Ironsi and his host, Lt. Colonel Adekunle Fajuyi, as well as the killing of numerous Igbo officers. The coup was swift and decisive, placing northern officers in positions of control and paving the way for the appointment of Lt. Colonel Yakubu Gowon as Head of State.
Discussions among junior officers and some civilian elements hinted at the possibility of northern secession, but there was no formal or executed military plan to split the country at that time. Senior officers and civil servants ensured that the military remained committed to a unified Nigeria, averting the disintegration of the nation.
Ethnic Tensions and Violence
Following the coup, anti-Igbo violence escalated, especially in northern cities. Igbo civilians faced massacres and were forced to flee their homes, resulting in significant displacement and suffering. Estimates suggest that thousands were killed in the immediate months following the counter-coup. The violence deepened ethnic mistrust and created conditions that would later contribute to the Eastern Region’s declaration of independence as the Republic of Biafra in 1967.
Preservation of Unity
Despite the upheaval and fears of secession, Nigeria remained intact. Senior military officers, aided by civil servants, advocated for a united country. They persuaded junior officers and plotters to abandon any discussions of formal secession, emphasising that the nation’s survival depended on cohesion and compromise. The appointment of Gowon reflected a balance of regional interests and maintained continuity within the military hierarchy.
While some narratives suggest a plan called “Operation Araba,” historical documentation shows that this was not a formalised military strategy. References to “Araba” likely reflected informal discussions about regional dissatisfaction and the desire to “divide” political power, but it never materialised into an actionable plan.
Aftermath and Long-Term Implications
The July counter-coup reshaped Nigeria’s military and political landscape. Northern dominance within the army increased, and the country’s leadership faced the challenge of rebuilding trust among ethnic groups. Although the nation survived as a unified state, the events laid the groundwork for the civil war that erupted in 1967 when the Eastern Region declared independence as Biafra.

The counter-coup demonstrated the fragility of post-independence Nigeria, showing how ethnic tensions, grievances over governance, and military intervention could threaten national stability. The resolution of the crisis highlighted the importance of mediation, compromise, and strategic leadership in preserving unity.
The July 1966 counter-coup was a turning point in Nigerian history. It showcased the interplay between military power and ethnic politics while demonstrating how coordinated leadership and intervention can prevent national disintegration. The events highlight that, while fears of secession were real, decisive actions by senior military officers and civil servants kept Nigeria intact. This period serves as a reminder of the delicate balance required in multi-ethnic societies and the long-term consequences of unresolved grievances.
Author’s Note
The July 1966 counter-coup remains one of Nigeria’s most consequential military episodes. It demonstrates how quickly political violence can escalate and the central role the military played in shaping governance during Nigeria’s early post-independence years. While some narratives suggest northern secession was considered, verified historical evidence shows that senior officers and civil servants ensured the country remained united. The events also illustrate the consequences of ethnic tension and centralisation policies, lessons that continue to inform Nigeria’s political discourse today.
