Nigeria was not yet a year into its second decade of independence when the foundations of the country began to shake.
The crisis did not begin with the first civilian killed in a riot. It began inside the state itself.
On 15 January 1966, soldiers overthrew Nigeria’s civilian government in a coup that killed Prime Minister Sir Abubakar Tafawa Balewa, Northern Premier Sir Ahmadu Bello and several other senior political figures.
Seven months later, another military coup killed Major General Johnson Aguiyi Ironsi and Lieutenant Colonel Adekunle Fajuyi and unleashed widespread killings within the army.
Between those two coups came demonstrations, riots, political suspicion and the rapid deterioration of relations between Northern and Southern Nigerians.
Then came the attacks on Easterners living in the North.
By September and October, the crisis had become a human catastrophe.
For Hassan Usman Katsina, the military governor of Northern Nigeria, the challenge was no longer simply how to govern a region.
It was how to exercise authority over a region in which grief was becoming anger, anger was becoming suspicion, and suspicion was beginning to become revenge.
Katsina did not stop the massacres of 1966. He could not.
But in several critical moments, especially as military discipline collapsed in Kano, he tried to restore order before the violence became even more destructive.
His story is therefore not the simple story of a general who saved Northern Nigeria.
It is the story of a man standing inside a collapsing system, trying to control forces that were becoming increasingly difficult for anyone to control.
The Man Who Came From the Emirate
Hassan Usman Katsina occupied an unusual position in Nigerian public life.
He was born in 1933 into the ruling family of Katsina.
His father, Usman Nagogo, was Emir of Katsina, while his grandfather, Muhammadu Dikko, had also been Emir.
The emirate was not simply a ceremonial institution.
Northern Nigeria’s traditional rulers possessed considerable influence over political, social and religious life. Long before independence, the emirates had been central to the organisation of authority across the region.
Katsina therefore grew up knowing how traditional power worked.
But he did not remain within the traditional system.
He entered the Nigerian Army in 1956 and became part of a new generation of Nigerian officers who were expected to serve a modern state rather than an emirate.
His military training included time at Mons Officer Cadet School and the Royal Military Academy Sandhurst in Britain.
By independence in 1960, Katsina was already building a career in an institution that would soon become the most powerful political organisation in Nigeria.
That institution was the army.
He could hardly have known how quickly that institution would become divided against itself.

15 January 1966 Changed Northern Nigeria
The first military coup came on the night of 14 January and continued into 15 January 1966.
The conspirators targeted political and military leaders.
In Kaduna, Major Chukwuma Kaduna Nzeogwu and the soldiers under his command moved against the Northern regional government.
Ahmadu Bello was killed.
The death was profoundly significant.
Bello was the Sardauna of Sokoto, Premier of the Northern Region and the most influential politician in Northern Nigeria.
He had been the central figure of the Northern People’s Congress and one of the principal architects of Northern political power in the First Republic.
His assassination left Northern Nigeria without the man who had come to symbolise its political leadership.
The Prime Minister, Tafawa Balewa, was also killed.
So were senior Northern officers, including Brigadier Samuel Ademulegun and Brigadier Zakariya Maimalari.
The killings produced an enormous psychological shock.
But the reaction was shaped by another fact.
Several of the prominent coup plotters were Igbo officers.
This encouraged the belief among many Northerners that the coup was an attack by the Igbo against the North.
That conclusion was far more complicated than the reality of the coup.
The conspirators were military officers pursuing their own political and institutional objectives. They did not represent every Igbo person in Nigeria.
But once the killings had been interpreted through an ethnic lens, ordinary Igbo civilians began to be associated with the actions of officers they had never met.
That was one of the most dangerous developments to emerge from the January coup.
Katsina Becomes Governor
Major General Johnson Aguiyi Ironsi eventually became head of the new military government.
One of his most important decisions was the appointment of new military governors for Nigeria’s regions.
Hassan Katsina became military governor of Northern Nigeria.
The appointment placed a young Northern officer at the head of the country’s largest region at precisely the moment when its political leadership had been decapitated.
He faced several competing pressures.
Northern civilians were angry about the deaths of their leaders.
Southern and Eastern Nigerians living in the region were increasingly nervous about their safety.
The army was trying to establish control.
Traditional rulers remained influential.
And the federal government in Lagos was attempting to prevent Nigeria from falling apart.
Katsina had to govern all of these realities simultaneously.
The May Crisis
The next major explosion came in May 1966.
Ironsi’s government introduced Decree No. 34.
The decree abolished the federal system and replaced it with a unitary structure.
The decision had a particularly profound effect in the North.
Federalism was not merely an abstract constitutional arrangement.
The regional governments had provided the major political framework through which Northern leaders exercised authority.
The Northern Region was also enormous and contained communities with different histories, languages and political interests.
After the January killings, many Northerners already suspected that their political position had been weakened.
The abolition of the federal structure therefore looked to many like another blow.
Demonstrations and riots broke out.
Katsina imposed curfews in troubled areas, including Kano and Zaria.
He also declared military zones in places affected by unrest.
But the crisis demonstrated that force alone would not be enough.
The Emirs Enter the Crisis
Katsina brought Northern traditional rulers together in Kaduna.
This was one of the most important aspects of his response.
The military government possessed weapons and legal authority.
The emirs possessed something different.
They had longstanding relationships with the communities they ruled.
The Sultan of Sokoto and other traditional leaders could communicate appeals for calm through established social and religious networks.
Sir Abubakar III, the Sultan of Sokoto, appealed for restraint.
The traditional authorities were therefore drawn into the effort to keep the May disturbances from developing into a much larger confrontation.
Katsina’s position made him particularly suited to this approach.
He understood the military system because he was an officer.
He also understood the authority of the emirate system because he had been raised within it.
That combination became increasingly important as the year progressed.
The July Counter Coup
The fragile peace did not last.
On 29 July 1966, Northern soldiers launched a counter coup.
The coup resulted in the death of Ironsi and Fajuyi in Ibadan.
It also led to widespread killings of Southern officers.
The Nigerian Army was now experiencing a crisis within the crisis.
The January coup had destroyed trust between officers.
The July counter coup destroyed even more of it.
Northern soldiers believed that the new government had failed to punish the men responsible for January.
Southern officers increasingly feared Northern retaliation.
The army’s regional divisions were becoming impossible to ignore.
And the consequences were moving steadily beyond the barracks.
The logic of revenge was becoming established.
If January had killed Northern leaders, July could be presented as revenge.
But once July created new victims, another round of revenge became possible.
This was the beginning of a cycle that would soon involve civilians on a much larger scale.
The Army Was No Longer Simply an Army
This was the environment in which Katsina had to operate.
The Nigerian Army had been created as a national institution.
Officers from different regions served together.
They trained together.
They were supposed to obey the same chain of command.
But after January and July, many soldiers increasingly viewed one another through regional identities.
A Northern soldier could see a Southern officer not simply as a fellow soldier but as a representative of the people he believed had attacked Northern interests.
A Southern soldier could look at a Northern colleague and wonder whether he would become the next target.
This transformation was devastating because the army possessed something ordinary political organisations did not.
Guns.
Once distrust entered an armed institution, political arguments could become lethal very quickly.
The September Attacks
By September 1966, the violence had moved decisively into civilian life.
Large scale attacks against Easterners began across Northern Nigeria.
The targets included Igbo civilians, but the wider atmosphere also endangered other people from the former Eastern Region and other Southerners.
The distinction between political responsibility and ethnic identity had largely disappeared in the minds of many attackers.
This was the terrible transformation of the crisis.
A person did not have to be a politician.
He did not have to be a soldier.
He did not have to have supported the January coup.
Being Igbo or being perceived as an Easterner could be enough to make someone a target.
The consequences were enormous.
Families who had lived in Northern cities for years began searching for ways to leave.
Workers abandoned jobs.
Traders abandoned shops.
Children were separated from familiar surroundings.
Some people travelled south with little more than the clothes they were wearing.
Others were killed before they could escape.
Kano Was More Than a City
Kano was particularly important because it was one of the major commercial centres of Northern Nigeria.
For generations, the city had connected the North to long distance trade networks stretching across West Africa.
Its markets attracted merchants and workers from different parts of Nigeria and beyond.
Igbo traders and professionals had also established themselves there.
This meant that the violence had an economic dimension as well as a political one.
When Easterners fled Kano, they did not simply disappear from a population register.
Businesses were abandoned.
Commercial relationships were disrupted.
Homes were emptied.
Communities that had developed over years were suddenly broken apart.
The violence was therefore changing the social geography of the city.
And inside Kano was another source of danger.
The Nigerian Army’s 5th Battalion.
The 5th Battalion and the Breakdown of Command
The 5th Battalion had become one of the most important military units in Northern Nigeria.
Its soldiers had been caught in the growing conflict between Northern and Southern officers.
By October, the unit was no longer operating in the normal atmosphere of a disciplined national army.
Northern soldiers had witnessed the killings of January.
They had experienced the counter coup.
They had heard stories about what was happening elsewhere.
Many were afraid that they would be attacked.
Some were also angry.
The result was an increasingly unstable military environment.
Lieutenant Colonel Mohammed Shuwa, who commanded the battalion, was among the officers attempting to maintain discipline.
But even commanders who wanted to prevent violence faced a serious problem.
A command structure depends upon trust.
If soldiers believe their officers cannot protect them, they may stop obeying.
If they believe another ethnic group is preparing to attack them, they may decide that orders from above are less important than their own survival.
That was the situation developing in Kano.
1 October: The Kano Mutiny
On 1 October 1966, soldiers in Kano mutinied.
The event was one of the clearest signs that the crisis had moved beyond political disagreement.
Armed men were now challenging their own military command.
Violence spread within the barracks and into the wider city.
Southern officers were particularly vulnerable.
Civilians were also caught in the violence.
The situation was dangerous for another reason.
Kano was not an isolated military post.
It was a major city filled with civilians, businesses, transport routes and communities.
A military mutiny in such a place could quickly become a much wider urban catastrophe.
Hassan Katsina had to act.
Katsina and the Emir of Kano
Katsina’s response involved more than military force.
He worked with the Emir of Kano in efforts to restore order.
The importance of this cannot be understood simply as a meeting between two powerful men.
It reflected the unusual political structure of Northern Nigeria.
The military government was the formal authority.
But the emirate remained an important source of social legitimacy.
In an atmosphere where soldiers were refusing to obey military authority, an appeal from a respected traditional ruler could reach people differently from an order issued from military headquarters.
The combination was significant.
Katsina could deploy military power.
The emir could appeal to the social and moral authority of the traditional institution.
Together, they attempted to prevent the mutiny from turning Kano into an even larger battlefield.
Southern Officers Needed Protection
The danger facing Southern officers also became a test of Katsina’s ability to maintain a national army.
Among the officers whose safety became a concern was Lieutenant Colonel Olusegun Obasanjo.
Obasanjo was Yoruba rather than Igbo, but by this stage the distinction did not necessarily guarantee safety.
The atmosphere had become so charged that Southern officers could be viewed with suspicion regardless of their individual actions.
Protecting such officers mattered.
If Southern officers were systematically killed or forced to flee the North, the Nigerian Army would lose the possibility of functioning as a genuinely national force.
Katsina therefore had an interest in protecting officers whose regional identity had suddenly become dangerous.
The episode also shows why the history cannot be reduced to a simple conflict between two completely united ethnic blocs.
There were Northern officers trying to protect Southern colleagues.
There were Southern officers trying to survive.
There were Northern civilians who rejected the violence.
There were also people who participated in it.
The society was not divided into two perfectly organised camps.
It was far more chaotic and human than that.
The Rumours That Made Everything Worse
One of the most powerful forces in 1966 was something that could not be seen.
Rumour.
Stories travelled through military barracks, markets, transport stations, neighbourhoods and religious communities.
A report of an attack in one city could create panic hundreds of kilometres away.
A claim that another community was preparing to strike could lead people to arm themselves.
Once armed people gathered, their presence could frighten another community into believing the rumour was true.
That community might then mobilise.
The mobilisation could then be interpreted as confirmation of the original rumour.
Violence could follow.
This was one reason the crisis became so difficult to control.
The authorities were not fighting only organised opponents.
They were fighting fear itself.
Katsina attempted to counter dangerous rumours and calm communities.
But government credibility was already badly damaged.
People who had watched their political leaders assassinated and their soldiers killed were not necessarily prepared to believe that official assurances meant safety.
The Pogroms Continued
Katsina’s intervention in Kano did not bring an end to the violence across Northern Nigeria.
The massacres continued.
This distinction is essential.
He could intervene in particular situations.
He could impose restrictions.
He could attempt to control soldiers.
He could cooperate with emirs.
But he could not personally control every town, every military unit or every civilian crowd across the vast Northern Region.
The attacks therefore continued to claim lives.
Easterners fled in enormous numbers.
The trains, roads and other routes leading south became part of a mass movement of people trying to return to the East.
The return was traumatic.
Many refugees arrived with stories of relatives who had been killed.
Some had lost their homes.
Others had lost businesses they had spent years building.
The crisis was no longer something that could be solved simply by restoring calm in one city.
It had changed the political relationship between entire regions.
What Happened to Northern Commerce?
The violence also had consequences for Northern cities themselves.
Easterners had played important roles in commerce, transport, skilled work and the professions in many parts of Nigeria.
Their departure disrupted established networks.
Shops closed.
Properties were abandoned.
Businesses changed hands.
Customers disappeared.
Suppliers lost established relationships.
The human cost was therefore accompanied by economic disruption.
The North was not simply losing a population.
It was losing people who had become part of the commercial and professional life of its cities.
At the same time, the East was receiving large numbers of people who needed housing, employment and food.
The violence had created an economic problem on both sides.
Katsina Was Facing a Crisis Larger Than His Office
By late 1966, the governor’s problem had become almost impossible.
He had to deal with a population grieving over the deaths of Northern leaders.
He had to manage soldiers whose loyalty to the chain of command had been damaged.
He had to protect civilians.
He had to work with traditional rulers.
He had to respond to rumours.
He had to maintain the authority of the federal military government.
And he had to do all of this while the relationship between Northern Nigeria and the Eastern Region was collapsing.
There was no single order capable of solving that.
The problem was structural.
Nigeria’s political system had lost credibility.
The army had lost unity.
Communities had lost trust.
And thousands of people had already lost their homes and relatives.
Aburi: The Crisis Reaches the Negotiating Table
In January 1967, Nigeria’s military leaders met at Aburi in Ghana.
The meeting was intended to find a political solution.
The key figures included Yakubu Gowon, who had emerged as Nigeria’s head of state after the July counter coup, and Chukwuemeka Odumegwu Ojukwu, military governor of the Eastern Region.
Hassan Katsina was also present.
The discussions revealed just how serious the breakdown had become.
Katsina described the Kano mutiny and the difficulty of controlling Northern soldiers.
The significance of his account was enormous.
It demonstrated that military authority had not merely been weakened politically.
It had been challenged physically by the soldiers themselves.
The commander could give an order.
The soldier could refuse.
Once that happened, the state was in danger of losing its most powerful instrument of coercion.
Katsina’s experience in Kano therefore gave him a particular understanding of what continued political confrontation could produce.
If the military itself fractured completely, there might be no institution left capable of keeping the country together.
The Aburi Moment
The leaders at Aburi were trying to negotiate a political settlement after months of bloodshed.
But they were no longer negotiating under normal circumstances.
The Eastern Region had received hundreds of thousands of displaced people.
The survivors had brought with them memories of the massacres.
Northern leaders feared another military coup.
Eastern leaders feared another attack.
The federal government wanted to preserve Nigeria’s territorial integrity.
Ojukwu increasingly demanded arrangements that would give the regions much greater autonomy.
Katsina’s experience of the Kano mutiny formed part of the larger argument about how Nigeria could prevent another breakdown.
But the agreements reached at Aburi did not ultimately resolve the crisis.
Interpretations of what exactly was agreed and how it should be implemented later became intensely disputed.
By then, the political relationship between the federal government and the East was already too damaged for easy reconciliation.
From Massacres to Secession
The consequences of 1966 continued to accumulate.
On 30 May 1967, Ojukwu declared the independence of the Republic of Biafra.
The federal government rejected the declaration.
On 6 July 1967, federal military operations began.
The Nigerian Civil War had started.
A country that had entered 1966 arguing over political power was now fighting over whether it would remain one country.
The chain of events was devastatingly clear.
The January coup had killed political leaders.
The political crisis had produced the July counter coup.
The counter coup had produced further military killings.
The military crisis had spilled into civilian communities.
The massacres had produced mass displacement.
The displacement had deepened political separation.
And the failure to reach a lasting settlement eventually produced war.
The Part of the Story That Must Not Be Lost
It would be easy to turn Hassan Katsina into a heroic figure who single handedly prevented a Northern catastrophe.
That would not be accurate.
He did not stop the pogroms.
He did not prevent the mass flight of Easterners.
He did not stop Biafra from declaring independence.
He did not prevent the civil war.
But the opposite portrayal would also be incomplete.
Katsina was not simply a passive observer while Northern Nigeria descended into violence.
He imposed curfews.
He attempted to restore military discipline.
He brought traditional rulers into the effort to calm the region.
He intervened during the Kano crisis.
He was involved in protecting Southern officers.
He attempted to counter destabilising rumours.
And he participated in the negotiations at Aburi when Nigeria was searching for a political escape from the crisis.
His importance therefore lies in the moments when he tried to hold together a system that was already coming apart.
Why Kano Matters So Much
The Kano episode offers perhaps the clearest picture of the problem Katsina faced.
Imagine the contradiction.
The military governor had authority over the army.
Yet soldiers were mutinying.
He needed soldiers to restore order.
Yet the presence of armed soldiers could itself frighten civilians.
He needed the support of the Northern population.
Yet some of that population was angry and suspicious of the federal government.
He needed to protect Southern officers.
Yet many soldiers were already viewing Southern identity with suspicion.
And when military authority alone proved insufficient, he had to rely on the emirate institution.
This was not normal government.
It was crisis management in a country whose institutions were being tested almost beyond their limits.
A Complicated Legacy
Katsina’s later career continued after the civil war.
He remained an important figure in Nigeria’s military establishment and served in senior positions.
But his experience in 1966 remains particularly significant because it reveals the complexity of the period.
He was both a product of Northern political society and an officer of the Nigerian Army.
He understood the anger of the North.
He also understood the danger of allowing that anger to destroy the army.
He belonged to a system that was increasingly divided along regional lines.
Yet he had reasons to preserve a national military structure.
He could not undo what had happened.
But he could attempt to stop the next stage of the collapse.
When Revenge Becomes Bigger Than the Original Crime
The tragedy of 1966 was that the country entered a cycle in which every group could point to its own dead.
Northern Nigerians remembered January.
Southern officers remembered July.
Easterners remembered the massacres.
Families remembered relatives who had disappeared.
Communities remembered houses that had been abandoned.
Each memory could become another reason for fear.
And each fear could become another reason for violence.
That was the environment in which Hassan Katsina operated.
His attempts to restore order were therefore not simply attempts to stop one riot.
They were attempts to prevent a chain reaction.
The effort ultimately failed on the national scale.
Nigeria went to war.
But individual interventions still mattered.
Protecting one officer mattered.
Stopping one mutiny mattered.
Preventing one crowd from attacking another mattered.
Keeping one city from descending further into chaos mattered.
History is often remembered through its final outcome.
But people experience history through the moments when someone either acts or does not act.
The Lesson of Hassan Katsina’s 1966
Hassan Usman Katsina’s story is important because it shows the terrifying speed with which a political crisis can become something else.
It began with a coup.
Then came assassinations.
Then suspicion.
Then another coup.
Then military killings.
Then civilian massacres.
Then mass displacement.
Then secession.
Then war.
At several points along that road, people attempted to slow the process.
Katsina was one of them.
His intervention did not rescue Northern Nigeria from violence.
The evidence does not justify saying that.
But when Kano’s military command was challenged, when Southern officers were vulnerable and when traditional authority was needed to help restore calm, he worked to prevent the breakdown from becoming even more complete.
That is the more revealing story.
Not a perfect hero.
Not a simple villain.
A military governor from an old Northern emirate, placed in charge of a region carrying enormous grief, suddenly forced to confront the possibility that revenge could destroy the very institutions meant to protect the people.
And once revenge entered the army, the danger was no longer simply that one community would attack another.
The danger was that Nigeria itself might cease to function.
By 1967, that danger had become reality.
EXPLORE NOW: Military Era & Coups in Nigeria
Author’s Note
Hassan Usman Katsina’s story captures one of the most painful lessons of Nigeria’s 1966 crisis. He governed a Northern Nigeria devastated by the murder of its political leaders, shaken by military coups and increasingly consumed by ethnic suspicion. He could not prevent the massacres of Easterners or stop the country from entering civil war, but his efforts to restore military discipline, work with traditional rulers, protect endangered officers and contain violence in places such as Kano showed the importance of resisting revenge before it becomes uncontrollable. His story ultimately reminds us that when fear turns neighbours into enemies and every new death becomes a reason for another, even the strongest institutions can begin to collapse.
