Long before King Oyo Nyimba Kabamba Iguru Rukidi IV became one of the world’s youngest monarchs, before his image as the child king travelled across Uganda and beyond, another prince had taken a decision that would permanently redraw the political map of western Uganda, regarding monarchies, writes Samuel Kamugisha.
His name was Kaboyo.
The son of Omukama Nyamutukura Kyebambe III of Bunyoro, Kaboyo broke away from his father’s kingdom in the early 19th century and established his own realm.
He became Olimi I, the founder of the Tooro Kingdom.
More than two centuries later, his descendant Oyo would die at the age of 34 after more than three decades on the throne.
Between the founder and the child king lay a remarkable succession of monarchs — some powerful, some short-lived, some driven from their kingdom, and others caught in wars that turned the royal throne into the prize of competing dynasties and neighbouring kingdoms.
The story of Tooro is therefore not simply a list of kings.
It is the story of a kingdom that was born out of rebellion, nearly disappeared, was restored with the help of a colonial power, survived the abolition of Uganda’s monarchies and eventually produced a king who grew up in the public eye.
THE BIRTH OF TOORO
Tooro’s origins are closely connected to Bunyoro-Kitara.
In the early 19th century, Prince Kaboyo, a son of Omukama Nyamutukura Kyebambe III, established a separate political domain west of the main Bunyoro kingdom.
Historical accounts differ on the precise year of the separation, but Tooro’s own historical narrative places the origins of the kingdom in this period.
Kaboyo became Omukama Olimi I.
His rebellion created a new Babiito kingdom.
That decision would have consequences for generations.
The royal house that Kaboyo established would continue to rule Tooro through wars, colonialism, political abolition and restoration.
Olimi I therefore occupies a position unlike any other monarch in Tooro history.
Every king who followed inherited something from him.
The kingdom itself.
WHEN BROTHERS FOUGHT FOR THE THRONE
Olimi I’s death did not produce a smooth succession.
Instead, Tooro entered a period of dynastic instability that would dominate much of the second half of the 19th century.
His successor, Kazana Ruhaga I, ruled only briefly.
According to accounts preserved by the Tooro Kingdom, Ruhaga was killed by his brother Kasunga Kyebambe Nyaika, who subsequently took the throne.
But Nyaika’s accession did not settle the succession question.
Another royal, Kato Rukidi I, challenged him.
The dispute soon became more than a family quarrel.
Buganda became involved.
With Buganda’s military support, Kato succeeded in taking the Tooro throne and forcing Nyaika out.
But Kato’s victory was temporary.
Nyaika eventually returned.
The throne changed hands as rival royal factions fought for control.
The succession history of this era is complicated, and historical sources differ over the precise order and length of some reigns.
Among the names associated with this turbulent period are Rukidi II, Rububi Kyebambe II, Kakende Nyamuyonjo and Katera.
Their stories are connected by one recurring theme: instability.
The Tooro throne was no longer simply inherited.
It was contested.
BUGANDA AND BUNYORO ENTER THE STRUGGLE
The conflicts inside Tooro unfolded against a much larger regional contest.
Buganda and Bunyoro were powerful kingdoms, and Tooro occupied territory of considerable strategic importance.
The young kingdom therefore found itself exposed to the ambitions of its neighbours.
Bunyoro’s influence became particularly important.
One of the victims of this changing balance of power was Olimi II, also known as Nyaika Mukabirere.
In 1875, he was captured and taken to Bunyoro by forces associated with Omukama Kabalega.
His removal represented a major blow to Tooro’s independence.
The kingdom’s royal succession had become entangled in the politics of Bunyoro, Buganda and the wider Great Lakes region.
THE KINGDOM DISAPPEARS
By around 1880, Tooro’s independent monarchy had effectively collapsed.
The kingdom came under Bunyoro’s control.
For roughly a decade, Tooro did not have an independent monarch exercising authority over the kingdom as its earlier kings had done.
The monarchy had disappeared from the political map.
But the royal lineage had not.
Far away from the centre of the struggle, a young member of the royal family was growing up.
His name was Daudi Kasagama.
He would eventually return.
KASAGAMA: THE KING WHO CAME BACK
Kasagama was a son of Olimi II.
As a child, he and his mother fled the violence surrounding the Tooro succession.
He found refuge in Buganda.
By the time he was ready to return, the political environment of East Africa had changed dramatically.
The British were expanding their influence.
Christian missionaries were establishing new institutions.
African kingdoms were being drawn into treaties, alliances and conflicts with European powers.
In 1891, Kasagama returned to Tooro with British support.
He was installed as Omukama in August of that year.
The Tooro monarchy had been restored.
Kasagama became Kyebambe IV, but history would remember him particularly as the king who brought the kingdom back after its long political disappearance.
His reign also marked the beginning of a new relationship between the Tooro monarchy and colonial power.
Kasagama entered agreements with the British and converted to Christianity.
Under his leadership, Tooro adapted to the new political reality rather than disappearing with the old one.
He ruled until 1928.
His reign was long enough to transform the restored monarchy into an institution capable of surviving the colonial era.
RUKIDI III AND A CHANGING UGANDA
Kasagama was succeeded by George David Matthew Kamurasi Rukidi III in 1928.
Rukidi III ruled for almost four decades.
His reign covered some of the most important years in Uganda’s modern history.
When he became king, British colonial rule was firmly established.
When he died in 1965, Uganda was independent.
The political world around the Tooro throne had therefore changed almost completely during his reign.
Rukidi III’s long rule provided continuity as Uganda moved from colonial administration towards independence.
He died in December 1965.
His successor was his son, Patrick David Matthew Kaboyo Olimi III.
The new king would inherit the throne at a moment when the future of Uganda’s traditional kingdoms was about to be dramatically altered.
OLIMI III AND THE ABOLITION OF THE KINGDOMS
Olimi III became Omukama in 1965.
Less than two years later, his kingdom was abolished.
In 1967, President Milton Obote’s government abolished Uganda’s traditional kingdoms as part of a wider constitutional transformation.
The Tooro monarchy was suspended.
For more than two decades, the royal institution existed without the formal public role it had historically enjoyed.
The abolition was one of the greatest interruptions in Tooro’s history.
But it did not erase the monarchy from the consciousness of its people.
The royal family survived.
So did the traditions.
And so did the expectation that one day the kingdom would return.
1993: THE RETURN OF THE KINGS
That moment came in the early 1990s.
In 1993, Uganda restored its traditional cultural institutions.
Tooro’s monarchy was revived.
But Olimi III would only enjoy the restored kingdom for a short time.
He died in August 1995, aged 49.
The succession that followed would produce one of the most extraordinary royal stories in contemporary Africa.
ENTER OYO
Oyo Nyimba Kabamba Iguru Rukidi IV was born on April 16, 1992.
When his father died in 1995, Oyo was only three years old.
He nevertheless became the Omukama of Tooro.
A child had inherited a kingdom.
His enthronement attracted enormous attention.
Photographs of the tiny monarch in royal regalia became symbolic of Tooro’s unusual place in the modern world.
But behind the ceremony was a practical problem.
A three-year-old could not personally administer the affairs of a kingdom.
Members of the royal family and Kingdom institutions therefore helped guide the monarchy as Oyo grew up.
For the next several years, the child king’s life was inseparable from the institution he had inherited.
He grew up under the gaze of the public.
FROM CHILD KING TO ADULT MONARCH
Time changed Oyo’s role.
The three-year-old became a schoolboy.
The schoolboy became a young man.
The young man became the adult Omukama.
And with adulthood came a more visible public role.
Oyo increasingly represented Tooro at cultural and national events and became associated with efforts to preserve the kingdom’s heritage while supporting development initiatives.
His reign also represented a new kind of Ugandan monarchy.
Unlike the pre-1967 kings, Oyo did not rule a sovereign political kingdom.
Uganda’s restored traditional institutions were cultural rather than political.
The king’s influence therefore rested on history, identity, tradition and the loyalty of his subjects.
For an entire generation, Oyo was the only Tooro king they knew.
His reign had begun before many of them were born.
THE KING WHO KNEW NO OTHER LIFE
That may ultimately be the defining feature of Oyo’s reign.
He did not choose the throne as an adult.
He inherited it as a child.
He did not first become a private citizen and later decide to become a king.
He grew up as a king.
His childhood, education, adulthood and public life unfolded alongside the institution of the Tooro monarchy.
By the time he reached his thirties, he had spent virtually his entire life carrying the title Omukama.
His reign eventually lasted more than 30 years.
It was longer than the reigns of many of his predecessors and spanned an extraordinary transformation in Ugandan society.
THE FINAL DAYS
In August 2026, concerns about Oyo’s health intensified.
The Tooro Kingdom appealed to the public to remain calm and pray for the monarch after reports emerged that he was critically ill.
He was receiving medical care in the United States.
The Kingdom did not initially disclose the nature of his illness.
Reports subsequently circulated about his condition, but the official communications remained cautious.
Then came the announcement that Tooro had lost its king.
Prime Minister Calvin Armstrong Rwomiire Akiiki announced that Oyo had died at approximately 10 p.m.
The king was 34.
The child who had inherited the throne in 1995 was gone.
His death brought to an end one of the longest and most unusual chapters in the history of the Tooro monarchy.
THE LEGACY OF THE KINGS
The history of Tooro cannot be reduced to a succession list.
Each monarch inherited a different kingdom.
Olimi I inherited no kingdom. He created one.
Ruhaga and Nyaika inherited a fragile throne and became embroiled in dynastic struggles.
Kato Rukidi demonstrated how external military alliances could determine who sat on the royal stool.
Olimi II experienced the growing power of Bunyoro over Tooro.
The succession struggles involving Rukidi II, Rububi, Kakende and Katera reflected a kingdom caught between competing royal factions and powerful neighbours.
Then came Kasagama, the exile who returned and restored the monarchy.
Rukidi III provided stability during the final decades of colonial rule and the transition to independence.
Olimi III became the king of a newly independent Uganda, only to see his monarchy abolished before witnessing its restoration.
And finally there was Oyo.
The child king.
The restored king.
The modern king.
The monarch who spent more than three decades at the centre of Tooro’s public identity.
FROM OLIMI TO OYO
The story that began with Kaboyo’s breakaway from Bunyoro has survived wars, political upheaval and constitutional change.
Tooro disappeared as an independent kingdom and returned.
Its kings were killed, exiled, defeated and restored.
Its royal institution was abolished and later revived.
Through all these changes, the Babiito dynasty survived.
That is the deeper story behind the succession from Olimi I to Oyo.
It is a story of political ambition, family conflict, regional power struggles, colonial intervention, abolition, restoration and continuity.
And now, following Oyo’s death, Tooro stands at another historical turning point.
The throne that once passed from brother to brother amid 19th-century wars must again pass to a new generation.
The next Omukama will inherit a kingdom very different from the one Kaboyo created in the 1800s.
But the crown itself carries the memory of every monarch who came before.
From Kaboyo Olimi I, the founder, to Oyo Rukidi IV, the child king who became an adult monarch, the history of Tooro has always been a story of survival.
The throne has changed hands.
The kingdom has changed shape.
Uganda has changed.
But the crown remains.
