On 15 January 1966, the First Republic of Nigeria was abruptly ended by a group of young army officers in a coup d’état. The attempt to unseat the civilian government resulted in the deaths of several senior political figures and senior military leaders. Within days, Major General Johnson Aguiyi‑Ironsi, the highest‑ranking surviving officer, assumed control of the government. This unprecedented event marked the beginning of military involvement in Nigerian politics and reshaped the nation’s trajectory.
Background to the Coup
The early 1960s in Nigeria were characterised by intense political rivalries, electoral disputes, allegations of corruption and regional tensions. The military was shaped by the same ethnic divisions that marked civilian politics. A group of mostly junior officers organised the coup, citing corruption, maladministration and breakdown of law and order as motivations. During the coup several federal and regional leaders were killed, including the Prime Minister Sir Abubakar Tafawa Balewa, the Premier of the Northern Region Sir Ahmadu Bello and the Premier of the Western Region Samuel Ladoke Akintola. Aguiyi‑Ironsi, who was not among the conspirators, suppressed the mutiny and took control of the government. News of these events spread slowly across the country.

Immediate Public Reaction
Confusion and Limited Awareness
In the days following the coup, many Nigerians were uncertain about what had happened. News dissemination was limited by the reach of radio and print media, and many citizens received information hours or days after events unfolded in Lagos, Kaduna and other centres. The sudden removal of political leaders and the absence of a clear civilian authority created widespread confusion.
Perceptions Among Elites and Soldiers
For political elites, civil servants and some segments of the military, the coup generated anxious debate rather than uniform celebration or anger. Many viewed the collapse of the First Republic with a mixture of hope for reform and apprehension about instability. The fact that many of the officers involved in the coup were from one region and that key politicians from other regions were killed contributed to perceptions of ethnic imbalance among military ranks.
Regional Interpretations and Emerging Tensions
Northern Nigeria
In the Northern Region, the deaths of the Prime Minister and the Sardauna of Sokoto were deeply felt. Politicians, community leaders and sections of the military saw the targeting of senior Northern figures as a threat. This perception contributed to rising frustration and mistrust within northern officers, creating political mobilisation among elites and rank-and-file soldiers.
Southern and Eastern Nigeria
In parts of the South, some individuals hoped the coup might lead to reform. However, evidence from January 1966 does not document widespread celebrations or uniform public support in these regions. Reactions were subdued and varied widely by locale.
Political Consequences and Later Reactions
Within a few months, reactions to the coup hardened into distinct regional narratives as the new military government announced reforms. Aguiyi‑Ironsi’s issuance of Decree No. 34 in May 1966, which abolished Nigeria’s federal structure and replaced it with a unitary system, intensified suspicion in the North and West. By July 1966, discontent among northern officers culminated in a counter‑coup. Major General Ironsi and his host, Brigadier Frederick Fajuyi, were assassinated, and Lieutenant Colonel Yakubu Gowon became Head of State.

Longer‑Term Legacy
The January 1966 coup and its aftermath set a precedent for military intervention in Nigerian politics. Initial public reactions, shaped by limited information and social divisions, evolved into long-standing narratives about ethnic marginalisation, governance and national identity. These narratives informed political debates for decades and contributed to the Nigerian Civil War in 1967.
Author’s Note
The January 1966 coup in Nigeria caused confusion and uncertainty among ordinary citizens and generated anxious debates among political and military elites. Regional perceptions and emerging ethnic narratives shaped subsequent political events, including the July 1966 counter-coup. The coup marked a pivotal moment in Nigeria’s post-independence history, highlighting the fragile nature of early civilian governance and laying the foundation for future military involvement in politics.
