Nigeria’s first republic, established after independence in 1960, was a fragile federation of diverse ethnic groups. By 1966, political crises, ethnic rivalries, and violent coups had destabilised the nation. The January 1966 military coup, followed by a July counter-coup and targeted violence, directly set the stage for the secession of the Eastern Region and the outbreak of the Nigerian Civil War (1967–1970).
The January 1966 Coup: Shattering the First Republic
On 15 January 1966, a group of young military officers launched a coup that resulted in the assassination of Prime Minister Sir Abubakar Tafawa Balewa, Northern Premier Sir Ahmadu Bello, and Western Premier Samuel Akintola. Major General Johnson Aguiyi-Ironsi, a senior officer, assumed control as Head of State.

While the coup aimed to restore stability and tackle corruption, it was widely perceived as favouring the Igbo-dominated military. This perception intensified regional suspicions and created a climate of mistrust between the North and the East.
Ironsi’s Centralisation and Growing Northern Anxiety
In May 1966, General Ironsi introduced Decree No. 34, abolishing the federal structure and centralising power. Intended to unify the country, it instead heightened northern fears of Igbo domination. Northern military officers, alarmed by the perceived threat, began planning to reclaim control, setting the stage for further upheaval.
The July 1966 Counter-Coup and Anti-Igbo Violence
On 28 July 1966, northern officers staged a counter-coup that resulted in the assassination of General Ironsi and Lieutenant Colonel Francis Fajuyi. Lieutenant Colonel Yakubu Gowon was appointed Head of State.
Following the counter-coup, widespread violence erupted against Igbo civilians and other Easterners living in the Northern Region. Tens of thousands fled to the Eastern Region to escape attacks. This mass displacement and targeted killings significantly escalated ethnic tensions and deepened the sense of insecurity among the Eastern population.
Failed Negotiations and the Secession of Biafra
Efforts to negotiate a political settlement, including the Aburi Conference in Ghana early in 1967, failed due to disagreements on implementation. Faced with continued insecurity and distrust of the federal government, the Eastern Region, led by Lieutenant Colonel Chukwuemeka Odumegwu Ojukwu, declared independence as the Republic of Biafra on 30 May 1967.
Outbreak of Civil War

The federal government, under General Gowon, rejected the secession and launched military operations on 6 July 1967 to reintegrate the Eastern Region. The conflict, which lasted until January 1970, involved conventional battles, blockades, and severe humanitarian crises. Casualties included combatants and civilians, with estimates of hundreds of thousands affected.
The 1966 coups created a cascade of political instability, ethnic tension, and distrust that made the secession of Biafra almost inevitable. The January coup, Ironsi’s centralisation policies, the July counter-coup, and anti-Igbo violence collectively ignited the Nigerian Civil War, a tragic chapter in the country’s history.
Author’s Note
The 1966 coups and subsequent events demonstrate how fragile political systems can collapse into conflict when trust between regions and ethnic groups is broken. The centralisation of power, violent reprisals, and failed negotiations led to the secession of Biafra and a devastating civil war. The key lesson is that inclusive governance and protection of all citizens are essential in diverse nations.
