The Gideon Orkar coup attempt of 22 April 1990 was one of the most serious armed challenges to the military government of General Ibrahim Badamasi Babangida. Rebel soldiers attacked strategic installations in Lagos, assaulted Dodan Barracks, seized federal broadcasting facilities and announced that Babangida’s government had been overthrown.
The uprising became particularly controversial because of the political programme announced over Radio Nigeria. Major Gideon Orkar declared that Sokoto, Borno, Katsina, Kano and Bauchi states were being temporarily excised from the Federal Republic of Nigeria, pending the fulfilment of conditions set by the coup makers.
The rebellion failed within hours. Babangida survived, loyal military formations rallied behind the government, and government forces regained control of strategic installations. The repercussions, however, lasted for months. Large numbers of soldiers and civilians were investigated or tried, and 69 people were eventually executed in two batches.
The Gideon Orkar coup attempt and the road to 22 April 1990
The uprising took place during a turbulent period in Nigeria’s political history.
Babangida had seized power from Major-General Muhammadu Buhari in a military coup on 27 August 1985. His administration promised political reform and eventually announced an elaborate transition programme intended to return Nigeria to civilian government.
At the same time, Nigeria was experiencing significant economic hardship. The Structural Adjustment Programme introduced under Babangida brought major changes to the economy, including currency depreciation, deregulation and reduced state intervention.
Economic difficulties, unemployment, declining living standards, allegations of official corruption, political repression and uncertainty about the transition to civilian rule contributed to widespread dissatisfaction.

Julius O. Ihonvbere, writing about the failed coup in The Journal of Modern African Studies in 1991, situated the uprising within this wider atmosphere of economic crisis, structural adjustment, political frustration and distrust of military rule.
The officers who moved against Babangida nevertheless chose an armed seizure of power. Their political programme also contained provisions that would have dramatically altered Nigeria’s federal structure and the status of millions of citizens.
The assault on Dodan Barracks
The operation began during the night of 21 to 22 April 1990.
Rebel soldiers moved against important military and communications installations in Lagos, which was still Nigeria’s federal capital. One of their most important targets was the Federal Radio Corporation of Nigeria.
As in several previous Nigerian military coups, control of national broadcasting was critical. Possession of the radio station allowed the coup makers to announce a change of government before they had secured complete control of the armed forces or the country.
Dodan Barracks, the seat of the military government and the official residence of Babangida, also came under heavy attack.
Babangida later described the events in his 2025 autobiography, A Journey in Service. He recalled unusual troop movements around his residence, followed by gunfire and increasingly heavy fighting.
His Aide-de-Camp, Lieutenant-Colonel Usman K. Bello, participated in the defence of the residence and was killed during the attack.
Babangida and members of his family were eventually moved to safer locations while loyal troops organised a counter-attack.
The fighting around Dodan Barracks became one of the defining moments of the uprising. The coup makers had struck directly at the centre of military power, but their failure to capture or kill Babangida proved crucial.
Gideon Orkar and the coup leadership
Major Gideon Gwaza Orkar became the defining public figure of the coup because he delivered its most famous radio announcement.
He was, however, one of several important officers associated with the conspiracy.
Other significant participants included Lieutenant-Colonel Anthony Nyiam and Major Saliba Mukoro. Several additional officers took part in the planning and execution of different aspects of the uprising.
Orkar nevertheless became inseparable from the event because it was his voice that Nigerians heard announcing the supposed overthrow of Babangida’s government. His subsequent arrest, trial and execution further established him as the most recognisable figure associated with the failed coup.
The extraordinary five-state declaration
The most controversial part of Orkar’s broadcast concerned Nigeria’s federal structure.
The coup announcement declared the temporary excision of Sokoto, Borno, Katsina, Kano and Bauchi states from the Federal Republic of Nigeria.
The broadcast named these five states specifically and described their exclusion as temporary, with conditions outlined for their eventual readmission.
Nevertheless, the proposal was extraordinarily far-reaching.
The announcement directed citizens originating from the five affected states who occupied public or private positions in the Middle Belt and southern Nigeria to return to their states. People from the Middle Belt and South living in the five states were similarly instructed to return home pending a future settlement.
The proposal therefore sought to reorganise the rights, positions and movements of Nigerian citizens according to geographical origin.
Nigeria’s state boundaries in 1990 were also different from those of today.
Sokoto State then included territory that later became Kebbi and Zamfara states. Borno included present-day Yobe. Kano included what later became Jigawa, while Bauchi contained the territory from which Gombe State was created.
The five-state declaration consequently affected a much larger geographical area than the modern state names alone might suggest.

Why the coup collapsed
The conspirators achieved surprise but failed to secure decisive control.
Most importantly, they did not capture or kill Babangida. The Head of State remained alive and communication with loyal commanders continued.
Senior officers and military formations elsewhere remained supportive of the government.
Lieutenant-General Sani Abacha, Chief of Army Staff and Chairman of the Joint Chiefs of Staff, emerged as one of the most important figures in the loyalist response. He broadcast a counter-announcement declaring that the coup had failed and that the military hierarchy remained loyal to Babangida’s government.
Government forces retook strategic installations as the rebellion unravelled.
The coup makers also failed to establish broad military support throughout Nigeria. Controlling a radio station and attacking the Head of State’s residence could create the appearance of a successful takeover, but the government retained important elements of the military command structure.
The five-state declaration also intensified opposition to the uprising. Its sectional provisions threatened the political position of a substantial part of the federation and complicated any attempt by the rebels to present themselves as representing the country as a whole.
By later on 22 April, loyalist forces had regained the initiative and the Gideon Orkar coup attempt had effectively collapsed.
Arrests, investigations and military trials
The suppression of the uprising was followed by an extensive investigation.
Soldiers and civilians were arrested, questioned and brought before special military proceedings.
Amnesty International recorded that the Nigerian government stated that 863 soldiers and civilians were tried between May and July 1990, with 764 acquitted and released. A further group was tried later in the year.
The substantive tribunal proceedings were conducted in camera. Defendants were represented within the military tribunal system rather than through the ordinary civilian court process, and there was no independent civilian judicial appeal from the convictions.
The trials carried the possibility of the death penalty, making the proceedings one of the most consequential aspects of the government’s response to the failed uprising.
69 executions after the uprising
The first major group of condemned coup suspects was executed on 27 July 1990.
Major Gideon Orkar and 41 other men were executed by firing squad, bringing the first group to 42.
But 42 was not the final number.
Further proceedings followed.
On 13 September 1990, another 27 men were executed.
The total number of people executed in connection with the April coup proceedings was therefore 69: 42 in July and 27 in September.
Amnesty International recorded that 72 people had received death sentences and that three sentences were believed to have been commuted.
The scale of the executions made the aftermath of the coup one of the harshest episodes of the Babangida period.
For Orkar, the failed uprising ended with his execution only three months after the attack on Dodan Barracks.
Regional grievances and a divided federation
Regional and minority grievances formed an important part of the rebels’ rhetoric.
Orkar’s broadcast attacked what the coup makers regarded as northern political domination and presented the uprising as acting partly in the interests of the Middle Belt and southern Nigeria.
Economic and political grievances were also important.
The coup makers criticised corruption, military authoritarianism, economic hardship and the direction in which Babangida was taking the country. Participants associated with the uprising also expressed dissatisfaction with Nigeria’s political structure and the distribution of power within the federation.
Yet the temporary removal of five states and restrictions proposed for their citizens gave the uprising an unmistakably sectional dimension.
The coup therefore combined military conspiracy, opposition to Babangida, minority and regional grievances, economic dissatisfaction and an attempted restructuring of Nigeria by force.
The significance of the 1990 coup
The failed uprising exposed serious vulnerabilities within Babangida’s military government.
Rebel soldiers had managed to penetrate the security structure of the federal capital, attack the official residence of the Head of State and seize one of the country’s most important communications institutions.
Babangida survived, but the attack demonstrated the seriousness of political divisions within sections of the armed forces.
The attempted coup also highlighted the continuing importance of Nigeria’s federal question. Arguments about regional power, minority interests, access to political authority and the distribution of national resources had shaped Nigerian politics long before 1990.
Orkar’s proclamation transformed those grievances into an extraordinary proposal to determine membership of the federation through military decree.
The government’s response demonstrated the enormous authority wielded by Nigeria’s military government. The rebellion itself lasted only hours, but arrests, tribunal proceedings and executions continued for months.
The events also strengthened the position of officers who had defended the government, particularly Sani Abacha, whose role in the loyalist response placed him prominently before the Nigerian public several years before he would become Head of State.

Conclusion
The Gideon Orkar coup attempt remains one of the most remarkable episodes in Nigeria’s military history.
On 22 April 1990, armed officers and soldiers attacked the Babangida government, assaulted Dodan Barracks, seized federal radio facilities and announced that a new political order had begun.
Their most controversial proposal was the temporary excision of Sokoto, Borno, Katsina, Kano and Bauchi states, accompanied by directives affecting citizens from those states living elsewhere in Nigeria.
The coup failed because the conspirators were unable to eliminate the existing command structure, secure Babangida or obtain sufficient military support across the country. Loyal forces regained control, while senior officers including Sani Abacha rallied behind the government.
The consequences were severe.
Major Gideon Orkar and 41 others were executed on 27 July 1990. Another 27 men were executed on 13 September, bringing the total to 69.
The events of 1990 consequently became a defining episode in the history of military rule in Nigeria, revealing deep divisions within the armed forces, unresolved tensions within the federation and the extraordinary political consequences that followed attempts to seize state power by force.
Author’s Note
The events of 22 April 1990 illustrate how political frustration, economic hardship, regional grievances and military ambition can combine to threaten the foundations of a state. Gideon Orkar and his fellow conspirators challenged the Babangida government, but their proclamation also proposed coercive measures that would have excluded millions of Nigerians according to state of origin. The government survived the uprising, while the military tribunals and 69 executions that followed became an enduring part of the episode’s legacy. The history of the coup remains a powerful reminder of the dangers created when political disagreement, sectional grievances and struggles over national power are pursued through military force rather than constitutional institutions.
