Major Patrick Chukwuma Kaduna Nzeogwu remains one of the most consequential figures in modern Nigerian history. As a key participant in Nigeria’s first military coup in January 1966, his actions marked the end of the First Republic and ushered in decades of military influence in the nation’s politics. This article presents a clear account of his life, the events of the coup, his later wartime role, and his enduring historical significance.
Early Life and Education
Patrick Chukwuma Kaduna Nzeogwu was born on 26 February 1937 in Kaduna, in what was then the Northern Region of British Nigeria. He was of Igbo descent and grew up in a region marked by cultural diversity. His early education took place in mission schools in Kaduna, where he exhibited discipline and academic promise.

In 1957, Nzeogwu enlisted as an officer‑cadet in the Nigerian Regiment of the Royal West African Frontier Force. His potential was recognised early, earning him admission to the Royal Military Academy Sandhurst in the United Kingdom. He completed his training and was commissioned as a Second Lieutenant in 1959, joining the Nigerian Army shortly before the country gained independence in 1960.
Military Career Before January 1966
Upon his return to Nigeria, Nzeogwu served in various units and was noted for his competence and leadership. By the early 1960s, he had risen to the rank of Captain and was appointed Chief Instructor at the Nigerian Military Training College (NMTC) in Kaduna. The position put him in charge of training many of Nigeria’s future military officers.
During this period, Nigeria grappled with political instability, regional rivalries and accusations of corruption within its civilian government. Tensions simmered across political parties representing the Western, Northern and Eastern regions. These national pressures formed part of the backdrop to the events of January 1966.
The January 1966 Coup
By the mid‑1960s, political dissatisfaction had grown among certain segments of Nigerian society and within the military. Many believed that the civilian government had failed to manage corruption, ethnic tensions and economic challenges. A group of mid‑ranking army officers began to discuss direct intervention as a means to effect change.
Events of 15 January 1966
In the early hours of 15 January 1966, a coordinated military operation was launched in several parts of the country. Nzeogwu was one of the most visible leaders of this action, particularly in northern Nigeria. Using troops under his command, he initiated a planned operation in Kaduna, purportedly under the pretext of a night exercise code‑named “Damisa,” meaning “leopard” in Hausa.
In Kaduna, troops arrested and executed several political leaders. Among those killed were Sir Ahmadu Bello, the Premier of the Northern Region, and his close associates. Other senior civil servants and officials were also detained or killed during the action. At the same time, more junior officers in Lagos, Ibadan and other cities took actions that resulted in further deaths of political and military figures.
The coup attempt did not capture the highest levels of national leadership. Although the Prime Minister, Sir Abubakar Tafawa Balewa, and other senior politicians were targeted, they were killed in separate locations or survived initially before later being confirmed dead. The federal government quickly began to unravel the situation as news of unrest spread.
Aftermath and National Impact
In the immediate aftermath, the military high command regained control of the situation. Major‑General Johnson Aguiyi‑Ironsi assumed power as Nigeria’s Head of State. The civilian government was dissolved, marking the end of the First Republic and the beginning of direct military rule.
The coup generated controversy. While some saw it as an attempt to remove corrupt politicians, others criticised its planning and execution, arguing it was poorly coordinated and disproportionately affected officials from certain regions. The events heightened regional and ethnic tensions that had already been present in Nigerian society.
Detention and Later Involvement in the Civil War
After the coup was suppressed, Nzeogwu was arrested and detained by the new military leadership. He spent several months in detention while the country’s political situation continued to deteriorate.
In 1967, Nigeria fractured along regional and ethnic lines, leading to the outbreak of the Nigerian Civil War. The Eastern Region declared independence as the Republic of Biafra. Nzeogwu, like many Igbo officers, aligned with the Biafran cause and was commissioned as a Lieutenant‑Colonel in the Biafran Army.
His role in the conflict was part of the early mobilisation of Biafran military operations. Nzeogwu did not serve as a major strategic commander in later stages of the war, and his involvement was operational in the early battles around the Nsukka front.
On 29 July 1967, Nzeogwu was killed near Nsukka during combat between Biafran and federal forces.
Historical Significance and Legacy
Major Nzeogwu’s actions on 15 January 1966 had far‑reaching consequences for Nigeria. The coup marked the first military intervention in the nation’s political affairs and directly led to the collapse of the First Republic. Military rule would continue, with interruptions, for several decades.
His legacy is viewed differently depending on perspective. Some scholars focus on his role as a military officer who acted within a group of conspirators without full coordination at the highest levels. Others emphasise the broader context of the coup as a symptom of deep political and ethnic challenges facing Nigeria at the time.
Author’s Note
Major Patrick Chukwuma Kaduna Nzeogwu was a Nigerian army officer whose life intersected with one of the most critical turning points in the nation’s history. From his training at Sandhurst and rise within the Nigerian Army to his leadership role in the January 1966 coup, his actions helped shape Nigeria’s political trajectory. Detained after the coup’s failure and later serving with Biafran forces, Nzeogwu’s career reflected the era’s instability and conflicting loyalties. His story is not one of myth or simple heroism but of a complex period in which military intervention irrevocably changed Nigeria’s political landscape.
