Behavioural objectives

By the end of the lesson, students should be able to:

  • State the main problems of the First Republic that led to the coup
  • Name the main plotters and the leaders who were killed on 15 January 1966

What problems in the First Republic led to the coup?

Nigeria’s civilian government (1960 to 1966) faced many serious problems.

Regional tensions

  • The Northern Region was bigger and had more people than the Eastern and Western Regions
  • Northern politicians had more power in the federal government
  • Southern politicians feared Northern domination
  • Ethnic groups did not trust each other

Western Region crisis

  • Chief Obafemi Awolowo and Chief S.L. Akintola disagreed about political alliances
  • Akintola formed a new party (NNDP) and allied with the Northern NPC
  • Violence broke out in the Western Region legislature
  • The federal government declared emergency rule in Western Region

The census controversy

  • A population count in 1962 was rejected
  • A new count in 1963 said the North had more people than the South
  • Southern leaders claimed the numbers were false
  • This caused more bad feelings because more people meant more power

Election problems

  • The 1964 federal elections had many problems
  • Many people could not vote
  • There was cheating and violence
  • UPGA (mostly Eastern and Western politicians) boycotted the election
  • The 1965 Western Region election was widely believed to be rigged

Corruption

  • Government officials were taking public money
  • Politicians lived in luxury while many people were poor
  • Government contracts were given to friends and family
  • Public services were not working well

“Operation Wetie”

  • After the 1965 Western Region election, violent protests started
  • People were burned alive (wetie means “wet with petrol, then burn”)
  • Law and order broke down
  • The government seemed unable to stop the violence
  • Many people died and property was destroyed

What problems did the armed forces have?

The armed forces had their own issues.

Colonial legacy

  • The Nigerian military was created by the British
  • It had British traditions and training
  • Many officers were educated abroad
  • They saw themselves as more disciplined than politicians

Ethnic composition

  • The officer corps had more Igbo officers from Eastern Nigeria
  • The rank and file soldiers were mostly from Northern Nigeria
  • This created tension within the military
  • Officers were aware of ethnic politics

Military professionalism

  • Military officers were unhappy with corruption in government
  • They felt politicians were ruining the country
  • Some believed the military could run the country better
  • They were concerned about political interference in military affairs

Who planned the coup, and what was the plan?

The plotters

A group of young officers planned the coup.

Key figures

  • Major Kaduna Nzeogwu, leader in the North
  • Major Emmanuel Ifeajuna, leader in Lagos
  • Major Adewale Ademoyega
  • Captain Nwobosi
  • Major Donatus Okafor
  • Most were majors and captains, not the most senior officers
  • Many were Igbo, but not all (Ademoyega was Yoruba)

Their motivations

  • They claimed they wanted to end corruption
  • They said they would stop regionalism and tribalism
  • They wanted to create a strong, united Nigeria
  • They were angry about politicians’ wealth and ordinary people’s poverty
  • Some had personal grievances against senior officers

The plan

The coup was carefully planned.

Timing

15 January 1966 was chosen because:

  • Commonwealth Prime Ministers were meeting in Lagos
  • Many senior officers would be at the meeting
  • Security would be focused on the foreign visitors
  • It was a weekend when people would be relaxed

Targets

  • Prime Minister Abubakar Tafawa Balewa
  • Premier of Northern Region, Sir Ahmadu Bello
  • Premier of Western Region, Chief S.L. Akintola
  • Federal Finance Minister, Chief Festus Okotie-Eboh
  • Senior army officers who might resist

Operations

  • Simultaneous attacks in Lagos, Kaduna and Ibadan
  • Key government buildings and communications would be seized
  • Army headquarters would be taken over
  • Government officials would be arrested or killed
  • The coup leaders would announce a new government

What happened on 15 January 1966?

The coup began in the early hours of the morning.

In Kaduna (Northern Region)

  • Major Nzeogwu led the attack
  • Soldiers surrounded Sir Ahmadu Bello’s house
  • The Sardauna (Ahmadu Bello) was killed along with his wife

  • Soldiers attacked Chief Akintola’s residence
  • Akintola reportedly fought back with his own guns
  • He was eventually killed
  • Government buildings were seized

In Enugu (Eastern Region)

  • No action was taken against Eastern leaders
  • Premier Michael Okpara was not targeted

Political vacuum

  • The President (Nnamdi Azikiwe) was out of the country
  • The Prime Minister was dead
  • There was confusion about who was in charge
  • Politicians asked the military to restore order

The handover of power

  • Remaining cabinet ministers met with Ironsi
  • They agreed to hand power to the military temporarily
  • The coup plotters surrendered when ordered by Ironsi
  • Nzeogwu surrendered in Kaduna
  • Ironsi became Head of State and Supreme Commander

What did the Ironsi regime do?

Initial actions

General Ironsi took several immediate steps.

Suspension of the Constitution

  • The 1963 Constitution was suspended
  • Regional governments were kept but with military governors
  • Political parties were banned
  • Decree No. 1 gave the military government full powers
  • The Supreme Military Council became the highest authority

Military governors

  • Lt. Col. Odumegwu Ojukwu: Eastern Region
  • Lt. Col. Hassan Katsina: Northern Region
  • Lt. Col. Francis Fajuyi: Western Region
  • Lt. Col. David Ejoor: Mid-Western Region
  • These officers ruled their regions under Ironsi’s authority

The coup plotters

  • The original coup leaders were arrested
  • They were not put on trial or publicly punished
  • This made many Northerners suspicious
  • Some believed Ironsi was part of the original plot
  • This created tension within the military

Unpopular policies

Ironsi made some decisions that caused problems.

Decree No. 34

  • It abolished the federal system in May 1966
  • It created a unitary government (all power at the centre)
  • Regions became “groups of provinces”
  • The civil service was unified
  • Northerners saw this as a plot to dominate them
  • It led to anti-Igbo riots in the North

Public reaction

  • Northerners felt the coup targeted mostly Northern leaders
  • No major Eastern leaders were killed
  • An Igbo officer (Ironsi) took power
  • Another Igbo (Ojukwu) governed the Eastern Region
  • The abolition of federalism seemed to threaten Northern autonomy
  • This created strong resentment in the North

What were the consequences of the coup?

Immediate effects

The coup changed Nigeria immediately.

End of the First Republic

  • Civilian democratic rule ended
  • Politicians lost power to soldiers
  • Democratic institutions were suspended
  • Rule by military decree began
  • Elections were cancelled

Military in politics

  • The military became the main political player
  • Soldiers became administrators and rulers
  • Military values entered Nigerian politics
  • Rank and command replaced democratic debate
  • This set a pattern for future military interventions

The July counter-coup

The first coup led to another coup six months later.

Northern revenge

  • On 29 July 1966, Northern officers staged another coup
  • General Ironsi was killed along with his host, Colonel Fajuyi, in Ibadan
  • Many Igbo officers were killed
  • Lt. Col. Yakubu Gowon (a Northern Christian) became Head of State
  • This was seen as a “revenge coup” for the January events

Ethnic violence

  • Anti-Igbo riots broke out in the North
  • Thousands of Igbo people were killed
  • Eastern Nigerians living in the North fled back East
  • Nigeria began moving toward civil war
  • Trust between regions was destroyed

Long-term impact

The coup had lasting effects on Nigeria.

Military rule as the norm

  • The coup began a pattern of military rule
  • Soldiers would rule Nigeria for nearly 30 of the next 40 years
  • Elections would be rare and often cancelled
  • Democracy was severely damaged
  • Coups became a way to change government

Civil War

  • The 1966 coups led directly to the Civil War (1967 to 1970)
  • Eastern Region declared independence as Biafra
  • About 1 to 3 million people died in the war
  • National unity was badly damaged
  • The effects of the war are still felt today

Centralisation of power

What were the different views of the coup?

The plotters’ view

The coup leaders had their own explanation.

  • They claimed they wanted to clean up corruption
  • They said they were patriotic Nigerians, not tribalists
  • They believed politicians had failed Nigeria
  • They saw themselves as revolutionaries
  • Major Nzeogwu became a hero to some Nigerians

Northern perspective

Many Northerners saw the coup differently.

  • They viewed it as an Igbo plot to take over Nigeria
  • They noted that most Northern leaders were killed
  • They pointed out that Eastern leaders were spared
  • They resented Ironsi’s policies, especially Decree No. 34
  • They felt they had to fight back to protect their interests

Eastern perspective

People from Eastern Nigeria had another view.

  • Many initially welcomed the end of a corrupt government
  • They did not see the coup as an “Igbo coup”
  • They pointed out that Ademoyega and others were not Igbo
  • They were shocked by the July counter-coup and Northern violence
  • They felt targeted and unsafe in other parts of Nigeria

What lessons does the first coup teach?

The coup showed several dangers in politics.

Ethnic politics

  • When political parties are based on ethnicity, tensions rise
  • When one group feels excluded, conflict can result
  • Diversity needs careful management in politics
  • National unity requires fair inclusion of all groups

Electoral problems

  • When elections are not fair, people lose faith in democracy
  • Violence may seem like the only option when voting fails
  • Strong, independent electoral systems are essential
  • Losers must accept results if democracy is to work

Corruption

  • Corruption undermines public trust
  • When leaders enrich themselves, people become angry
  • Military officers use corruption to justify coups
  • Good governance requires accountability
