The Men Behind Nigeria’s Rulers: A History Of Chiefs Of Staff & Executive Power

By NJORIGE LYNUS

THE title of Chief of Staff has occupied a peculiar place in Nigeria’s political history.

At different moments, it has represented a military second-in-command, a de facto vice presidency and, under civilian rule, a powerful presidential coordinating office.

Yet the title has never carried exactly the same meaning.

Its influence has depended largely on the political system, the personality of the head of government and the relationship between the occupant and the wider machinery of state.

That distinction matters when examining the succession of men who have occupied the position since independence.

The Military Origins of the Office

Nigeria’s first Chief of Staff, Supreme Headquarters was Brigadier Babafemi Ogundipe.

He assumed the position in January 1966 under Major General Johnson Aguiyi-Ironsi, following the military coup that ended the First Republic.

Ogundipe effectively became the second-ranking figure in the new military government. His tenure, however, lasted only months.

The July 1966 counter-coup transformed the political landscape. Aguiyi-Ironsi was killed, while Ogundipe lost his position as the military hierarchy shifted.

Vice Admiral Joseph Edet Akinwale Wey subsequently became Chief of Staff, Supreme Headquarters under General Yakubu Gowon.

Wey remained in the position for almost nine years. He also served as Chief of Naval Staff and became one of the most senior figures in Gowon’s administration. Historical accounts describe the office as the equivalent of a military vice presidency during this period.

However, the Gowon years also demonstrate why a simple list of names can conceal the complexity of Nigeria’s military bureaucracy.

Brigadier Emmanuel Ekpo is recorded as Chief of Staff, Supreme Headquarters during the Gowon period, including around the end of the civil war. That makes the chronology more complicated than a straight succession from Wey to Obasanjo.

Obasanjo & the Politics of Transition

General Olusegun Obasanjo became Chief of Staff, Supreme Headquarters after the July 1975 coup that brought General Murtala Mohammed to power.

The appointment placed him at the centre of a military government that promised a major restructuring of the Nigerian state.

That partnership ended abruptly in February 1976 when Murtala Mohammed was assassinated.

Obasanjo then became Head of State, while Brigadier Shehu Musa Yar’Adua became Chief of Staff, Supreme Headquarters.

Yar’Adua’s role went beyond routine military administration. He became a central figure in the regime’s political and economic programme.

His responsibilities included involvement in Operation Feed the Nation, while the administration pursued reforms in local government, public administration and national development. Historical material from the Shehu Yar’Adua Foundation also credits the administration with advancing a transition programme that eventually produced the 1979 return to civilian government.

That transition is particularly significant.

Nigeria had experienced military intervention as a response to political crisis. Yet the Obasanjo-Yar’Adua administration eventually handed power to an elected government in 1979.

The development also highlights a crucial distinction in assessing historical public officials.

Administrative effectiveness cannot be separated entirely from the political system in which an official operated.

The Civilian Interruption

When the military handed power to civilians in October 1979, the constitutional structure changed.

The office of military Chief of Staff, Supreme Headquarters disappeared.

In its place, the elected government operated under a presidential system with Alex Ekwueme as Vice President under President Shehu Shagari.

Ekwueme therefore occupies an important place in the chronology, even though he was not technically a Chief of Staff.

He was Nigeria’s first elected Vice President and served until the military coup of December 1983.

The interruption demonstrates that the history of the Chief of Staff cannot be understood independently of Nigeria’s changing constitutional arrangements.

Idiagbon & Executive Power

The military returned to power on 31 December 1983.

Major General Muhammadu Buhari became Head of State, while Major General Tunde Idiagbon became Chief of Staff, Supreme Headquarters.

Unlike the relatively administrative conception of the office in some earlier periods, Idiagbon exercised substantial influence over the Buhari government.

He became closely associated with the administration’s War Against Indiscipline and other policies.

The campaign targeted behaviours such as queue jumping, poor work ethics and indiscipline in public life.

Idiagbon’s role consequently became inseparable from the public identity of the Buhari government.

But the regime lasted less than two years.

In August 1985, General Ibrahim Babangida removed Buhari from power and replaced the Chief of Staff, Supreme Headquarters structure with the office of Chief of General Staff.

The Chief of General Staff Era

Commodore Ebitu Ukiwe became Babangida’s Chief of General Staff.

He served from August 1985 to October 1986 and functioned as the military president’s second-in-command. A contemporary Nigerian Year Book also identifies Ukiwe as Chief of General Staff within the Armed Forces Ruling Council.

His tenure was short.

Admiral Augustus Aikhomu succeeded him and remained Chief of General Staff until August 1993.

Aikhomu therefore became one of the longest-serving occupants of the position during the Babangida years. Like Ukiwe, he effectively operated as the military government’s vice-presidential figure.

After Babangida left office, Lieutenant General Oladipo Diya became Chief of General Staff under General Sani Abacha.

Diya remained in the position until December 1997.

His tenure unfolded during one of the most controversial periods of Nigeria’s military history, marked by political repression, the unresolved June 12 crisis and international pressure over Nigeria’s governance.

The Final Military Chief of General Staff

Vice Admiral Mike Okhai Akhigbe became Chief of General Staff under General Abdulsalami Abubakar in June 1998.

His tenure coincided with the final phase of military rule.

Within a year, Nigeria returned to civilian government.

The significance of the office changed once again.

The military model of a de facto second-in-command gave way to a civilian presidential system in which the Chief of Staff would operate primarily as an executive coordinator and political gatekeeper.

From Command Structure to Presidential Gatekeeping

Major General Abdullahi Mohammed became the first Chief of Staff to the President when Olusegun Obasanjo assumed office on 29 May 1999.

His appointment marked a major institutional shift.

The Chief of Staff was no longer a military deputy within a ruling council.

Instead, the office became part of the presidential machinery of a constitutional democracy.

Abdullahi Mohammed served through Obasanjo’s presidency and continued into the early period of Umaru Musa Yar’Adua’s administration.

He left office in June 2008.

Gbolade Osinowo succeeded him. However, Yar’Adua abolished the office in September 2008 and relied on a group of advisers instead. The office remained vacant until Goodluck Jonathan revived it in May 2010.

That episode revealed another important feature of the position.

The office exists at the discretion of the presidency and can become less influential or disappear altogether depending on how a president chooses to organise executive authority.

The Return & Expansion of the Office

Chief Mike Oghiadomhe became Jonathan’s Chief of Staff in 2010.

He remained until his resignation in February 2014.

General Jones Arogbofa then assumed the position and remained until Jonathan left office in May 2015.

Under President Muhammadu Buhari, Abba Kyari became Chief of Staff in August 2015.

Kyari remained one of the most influential figures around the presidency until his death in April 2020.

Professor Ibrahim Gambari subsequently became Chief of Staff in May 2020 and served until the end of Buhari’s administration in May 2023.

The present phase began when Femi Gbajabiamila assumed office on 14 June 2023 under President Bola Ahmed Tinubu.

The State House continues to identify Gbajabiamila as the incumbent Chief of Staff.

What Does “Best” Actually Mean?

That question cannot be answered responsibly by simply choosing one name.

The men occupied the office under fundamentally different political systems.

Ogundipe and Wey operated during military rule and national crisis. Obasanjo and Yar’Adua operated within a military administration that eventually transferred power to civilians. Idiagbon became associated with discipline-driven military governance. Ukiwe, Aikhomu, Diya and Akhigbe served under different phases of military rule, each shaped by its own political circumstances.

The civilian era produced another category of Chief of Staff.

Abdullahi Mohammed helped institutionalise the office in the Fourth Republic. Oghiadomhe, Arogbofa, Kyari, Gambari and Gbajabiamila operated within presidential administrations where political coordination, access management and policy implementation became central to the role.

Consequently, any serious assessment should ask different questions.

Which occupant strengthened institutional coordination?

Who helped advance measurable public policies?

Who protected the effectiveness of the presidency without weakening accountability?

Who contributed to democratic transition?

Who maintained institutional stability during political crisis?

And, perhaps most importantly, what did each office-holder leave behind after leaving government?

Those questions produce a more useful historical assessment than a simple popularity contest.

The history of Nigeria’s Chiefs of Staff is ultimately a history of changing executive power.

From military second-in-command to presidential gatekeeper, the office has repeatedly adapted to the country’s political transformations.

Its occupants may have changed, but one feature has remained constant: whoever controls access to the centre of power can exert considerable influence over how government actually functions.
