Failed Coup Attempts in Nigeria: 1960–2025

Since gaining independence in 1960, Nigeria has experienced a turbulent political history marked by several military interventions. While some coups succeeded in changing governments, others collapsed before achieving their goals. These failed or foiled attempts have played a major role in shaping Nigeria’s journey toward democracy and political stability.

1- The first coup attempt came on January 15, 1966, led by Major Chukwuma Kaduna Nzeogwu and a group of young officers. Their plan was to overthrow the civilian government of Prime Minister Abubakar Tafawa Balewa, accusing it of corruption and mismanagement. Although they killed key political figures including Balewa and Northern Premier Ahmadu Bello, the coup did not seize full control of the country. Major-General Johnson Aguiyi-Ironsi eventually took power, making it a partially successful but ultimately failed attempt in its original aim.

2- A more dramatic failed attempt occurred on February 13, 1976, when Lieutenant Colonel Bukar Dimka and his group tried to topple General Murtala Mohammed’s government. The coup began with the assassination of Murtala in Lagos, but within hours loyal soldiers restored order under General Olusegun Obasanjo. Dimka and several of his collaborators were captured and executed. The incident shocked the nation and led to tighter military discipline in subsequent years.

3- Nigeria faced another violent upheaval on April 22, 1990, when Major Gideon Orkar and a band of middle-ranking officers launched an audacious coup against General Ibrahim Babangida. They seized part of Lagos, took control of a radio station, and announced a new government that controversially sought to exclude certain northern states from Nigeria. The rebellion was swiftly crushed as Babangida narrowly escaped and regrouped loyal troops. Orkar and his fellow plotters were executed, and the coup remains one of the boldest yet most divisive in Nigeria’s history.

4- In December 1997, Nigeria was again shaken by reports of a coup plot against General Sani Abacha, this time allegedly led by his own deputy, Lt. General Oladipo Diya, alongside General Abdulkareem Adisa and others. The government announced that the conspirators had been caught before they could strike. Diya and his co-accused were arrested, tried, and sentenced to death in a televised trial, but they were later pardoned after Abacha’s sudden death in 1998. Many Nigerians still debate whether it was a real coup or a setup to purge Abacha’s inner circle.

5- During President Olusegun Obasanjo’s civilian administration in the early 2000s, rumours of another coup attempt surfaced. In 2004, reports claimed that some retired and serving officers, including those linked to the late Abacha regime, were plotting to remove Obasanjo. The government said the plot was foiled before it matured, but details were never made public. Many Nigerians saw it as a reflection of the lingering influence of military politics in the post-military era.

6- As Nigeria continued under democratic rule, occasional rumours of coup attempts persisted, especially during President Muhammadu Buhari’s tenure between 2015 and 2023. Security agencies occasionally warned of plots by disgruntled soldiers, but none were ever proven or publicly linked to real operations. These alerts nonetheless revealed ongoing tensions between civilian authority and sections of the military.

7- The most recent and controversial episode came in October 2025, when reports spread that several senior military officers had been arrested for planning a coup against the government of President Bola Ahmed Tinubu. Local media claimed the plan was to execute the coup on Nigeria’s Independence Day, October 1. The Defence Headquarters, however, denied any such plot, insisting the detained officers were being investigated for professional misconduct, not treason. Still, the subsequent replacement of top security chiefs and tight control of military information suggested that something significant had indeed occurred behind the scenes. Whether a real coup was foiled or the rumours were exaggerated remains uncertain, but the episode reignited debate about Nigeria’s enduring struggle with military intervention.

From Nzeogwu’s failed coup popularly know as the Igbo coup in 1966 to the alleged 2025 plot, Nigeria’s political journey shows how the military’s shadow has never fully disappeared from national life. Each failed coup has left lessons, about ambition, power, and the fragility of governance. Yet, despite these challenges, Nigeria’s democracy continues to endure, showing a growing commitment to civilian rule and constitutional order.
