Nigeria’s post-independence history has been shaped by a series of military coups. While some succeeded, many were foiled before they could unfold, largely due to internal intelligence, vigilant officers, and informants within the military. Understanding how these plots were exposed reveals the crucial role of information, loyalty, and timing in Nigeria’s turbulent political landscape.
This article highlights documented Nigerian coups from 1966 to 1985 where intelligence and reporting within the military played decisive roles, providing readers with a clear narrative of these pivotal events.
The First Coup: January 1966
On 15 January 1966, a group of young army officers attempted to overthrow Nigeria’s civilian government. Their plan targeted top political leaders and several state governors. While the coup succeeded in removing key figures, some parts of the operation failed because officers raised alarms within their commands, preventing the complete takeover of the army. The assassination of Prime Minister Tafawa Balewa and Northern leaders marked the coup’s success, yet Brigadier Samuel Ademulegun’s unit avoided total capture due to warnings from loyal officers. Lieutenant-Colonel Fajuyi was killed in Ibadan, highlighting both the success and partial limitations of internal reporting.

The July Counter-Coup: 1966
In response to the January coup, northern officers staged a counter-coup in July 1966, leading to the assassination of General Johnson Aguiyi-Ironsi and Colonel Fajuyi. Historical records show that certain northern officers were aware of the planned coup in advance, while loyal officers alerted troops to unusual movements, reducing potential resistance in some regions. The counter-coup reshaped Nigeria’s military leadership and further demonstrated the role of internal military intelligence in controlling outcomes.
The 1975 Coup
On 29 July 1975, General Murtala Muhammed successfully overthrew General Yakubu Gowon. This coup benefited from careful operational secrecy among the conspirators, with monitoring of troop movements by loyal officers in key locations ensuring minimal resistance in regions where intelligence and reporting maintained awareness of troop activities. This coup reflects a more organised use of intelligence and careful dissemination of information within the military compared to earlier events.
The 1983 Coup
On 31 December 1983, Major-General Muhammadu Buhari overthrew the civilian government of Shehu Shagari. Documented accounts highlight that intelligence units monitored dissent and potential unrest in the army, while conspirators moved quickly, using the knowledge that loyalist officers had been bypassed or misdirected. The success of this coup illustrated how internal military intelligence can enable swift and decisive action.
The 1985 Coup
On 27 August 1985, General Ibrahim Babangida staged a coup that overthrew Buhari. The operation was marked by careful planning and partial use of intelligence from within the army, while minimal resistance occurred due to timely awareness and coordination among the coup plotters. This event reinforced the understanding that Nigerian coups evolved to rely heavily on strategic use of information and loyalty networks.

How Informants and Intelligence Shaped Nigerian Coups
Across these events, it becomes clear that informants and vigilant officers alerted superiors to unusual troop movements or suspicious meetings. Military intelligence units maintained surveillance on potential dissent, creating institutional memory for subsequent coups, while chain-of-command reporting was critical in preventing wider chaos or failure during operations. Civilian leaks or foreign intervention played little or no verified role in exposing these Nigerian coups, making internal military awareness and reporting the decisive factor in outcomes.
Author’s Note
Nigeria’s history of military coups shows a clear lesson: information within the military determines the success or failure of coups. Informants, loyal officers, and intelligence units shaped outcomes from the January 1966 coup through Babangida’s 1985 takeover. While coups often capture public attention with dramatic narratives, the true factor behind exposure or containment was structured awareness, loyalty, and vigilance within the army, making intelligence the silent but decisive actor in Nigeria’s military politics.
