The Fall of the Old Oyo Empire was not the result of one betrayal, one invasion or one battle. By the time the inhabitants of Oyo-Ile abandoned the ancient imperial capital around 1836, the political system that had sustained Oyo’s power had been under severe pressure for decades.
At its height in the eighteenth century, Oyo was one of the most formidable states in West Africa. Its strength rested not simply on the authority of the Alaafin, but on a political system involving the Oyo Mesi, headed by the Bashorun, military commanders, provincial rulers and tributary authorities. Its army, especially its cavalry, helped extend Oyo influence far beyond the capital.
That system required cooperation. When political rivalry at the centre intensified, provincial commanders became increasingly independent and military coalitions became harder to sustain, the empire’s ability to respond to rebellion and external threats weakened.
The rise of Ilorin developed within a crisis that had begun before Ilorin became an emirate. Difficulties were already appearing on Oyo’s northern frontiers during the 1780s, before the reign of Alaafin Awole ended and long before the decisive transformation of Ilorin in the nineteenth century.
Fall of the Old Oyo Empire Began Before Afonja’s Revolt
One important warning came from the political struggles of the eighteenth century.
Bashorun Gaha, one of the most powerful figures in Oyo political history, accumulated extraordinary influence during the reigns of several Alaafins. His ascendancy eventually ended when Alaafin Abiodun defeated him with military assistance drawn from forces beyond the immediate palace establishment.
Abiodun’s victory strengthened royal authority, but the struggle demonstrated the growing importance of powerful military forces outside Oyo-Ile in determining affairs at the political centre.
Abiodun’s reign remained a period of considerable Oyo strength. The empire reached great power during the eighteenth century, but difficulties were emerging along its northern frontier before his death in 1789.
Oyo’s decline therefore did not begin with Afonja or with the arrival of Muslim fighters at Ilorin. Political rivalry, problems of provincial control and military pressures already formed part of the empire’s difficulties.
Awole’s Crisis and the Break with Ilorin
Alaafin Abiodun died in 1789 and was succeeded by Awole.
Awole’s reign became associated with rebellion, confrontation and political disorder. Yoruba traditions also preserve the famous account that, before his death, Awole pronounced a curse upon rebellious parts of the kingdom.
Afonja, the military commander associated with Ilorin, held the important office of Are Ona Kakanfo. He became one of the powerful figures involved in opposition to Awole.
The crisis eventually led to Awole’s removal and death around 1796.
After Awole’s death, another prince was selected as Alaafin. Afonja subsequently repudiated Oyo authority and established Ilorin as the centre of an increasingly independent political and military power.
The consequences were profound. Ilorin had previously existed within the Oyo political sphere. Under Afonja, it became the headquarters of a provincial challenge to the imperial government.
Ilorin did not immediately become an emirate. A period of political transformation separated Afonja’s break with Oyo from the later establishment of Muslim political authority there.
Afonja’s Revolt and the Muslim Mobilisation
Afonja’s rebellion against Oyo occurred before the major Muslim mobilisation associated with Ilorin.
Awole’s death came around 1796, while the Muslim uprising associated with Ilorin developed around 1817. The events were therefore separated by roughly two decades.

During the intervening period, Afonja attempted to maintain his political authority while strengthening Ilorin’s military position.
A central figure in the later transformation was the Muslim scholar Salih, widely remembered as Shehu Alimi. His followers included Muslims of different backgrounds.
Hausa, Fulani and Oyo Muslims participated in the emerging movement, while not every Fulani community in Oyo territory joined it. The conflict consequently developed through political, religious and military alliances that crossed ethnic boundaries.
Religion became an important organising force within Ilorin, but the struggle was also rooted in the earlier rebellion against Oyo authority.
Afonja eventually found himself unable to control the armed Muslim elements whose influence had increased within Ilorin. He attempted to restrain them, but the confrontation ended with his death, probably around 1823 or 1824.
His death fundamentally changed the character of Ilorin.
How Ilorin Became an Emirate
By the period of Afonja’s death, Salih was probably also dead. Leadership passed to Salih’s son, Abd al-Salam, commonly rendered Abdulsalami in later accounts.
Under Abd al-Salam, Ilorin became incorporated into the political network of the Sokoto Caliphate through Gwandu, which exercised authority over western emirates.
Ilorin had now ceased to be simply the headquarters of a rebellious Oyo commander. It had developed into an emirate with its own leadership, military resources and wider political connections.
The nature of the struggle changed accordingly.
Oyo was no longer attempting merely to suppress Afonja’s rebellion. It was confronting a new regional power based in territory that had once belonged to its political system.
Ilorin’s transformation placed increasing pressure on the remnants of Oyo authority.
Ogele, Mugbamugba and the Failure to Recover Ilorin
Following Afonja’s death, Oyo and its allies attempted to defeat Ilorin and restore their former position.
Among the major campaigns remembered from this period were Ogele and Mugbamugba. Other confrontations followed as Oyo continued trying to halt Ilorin’s expansion.
These wars failed to recreate the old political order.
Repeated military defeats strengthened Ilorin while exposing divisions among the forces attempting to resist it.
The problem was not simply cavalry or military technology. Oyo itself possessed a long cavalry tradition and had relied heavily on mounted warfare during its imperial expansion.
Political coordination became an increasingly serious weakness.
To defeat Ilorin, the Alaafin, provincial rulers, military commanders and emerging Yoruba war centres needed to maintain a strong and lasting coalition. Rival political interests repeatedly made such unity difficult.
Every failed campaign weakened the possibility of restoring the empire as it had existed during the eighteenth century.
The Final Coalition and the Disaster of 1835 to 1836
The decisive crisis came during the 1830s.
Alaafin Oluewu presided over one of the last major attempts to reverse Ilorin’s expansion. Oyo assembled forces from several towns and drew upon allies that included Bariba participants.
The coalition was large, but it suffered from serious internal disagreements.
Tensions developed between elements of the alliance, while powerful Oyo leaders pursued competing political interests. Atiba, a son of Alaafin Abiodun, possessed his own political following and claim to influence.
The coalition concentrated around Ogbomoso before advancing towards Ilorin.
During the campaign of approximately 1835 to 1836, its political divisions became disastrous. Several commanders withdrew rather than continuing the battle.
The remaining forces were defeated.
Alaafin Oluewu died as a consequence of the campaign. Accounts differ over whether he was killed during the fighting or captured and subsequently killed at Ilorin.
His death and the destruction of the coalition removed the remaining military protection available to the old imperial capital.
Why Oyo-Ile Was Abandoned
The fate of Oyo-Ile followed the catastrophic defeat of the Oyo coalition.
Lanloke of Ogodo attacked the capital after the campaign. His initial assault was repulsed.
The inhabitants of Oyo-Ile nevertheless feared that the main Ilorin army would follow.
With Alaafin Oluewu dead and the principal military coalition shattered, the city had become dangerously exposed.

Its inhabitants abandoned Oyo-Ile and moved towards settlements including Igboho and Kisi. The deserted capital was later plundered.
The abandonment of Oyo-Ile around 1836 marked the end of the ancient city as the functioning centre of the empire.
For centuries, Oyo-Ile had served as the political and symbolic heart of imperial Oyo. Its disappearance as a functioning capital represented the culmination of decades of political conflict, military failure and provincial fragmentation.
Atiba and the Birth of New Oyo
The abandonment of Oyo-Ile did not end the Alaafin institution.
Surviving members of the Oyo political establishment sought to preserve dynastic authority, and Atiba eventually emerged as Alaafin.
He did not permanently restore the royal court at Oyo-Ile.
Instead, Atiba established his court at Ago Oja, which developed into New Oyo, the present-day city of Oyo.
This represented both continuity and change.
The Alaafin institution survived. Oyo identity survived. Royal traditions continued.
The old imperial political structure did not.
At the same time, new military and political centres were becoming increasingly important across Yorubaland. Ibadan and Ijaye were among the powers that emerged from the wars, migrations and political reconstruction that accompanied the collapse of the old empire.
The end of Oyo-Ile therefore opened a new period in Yoruba history rather than bringing Yoruba political life to an end.
Afonja Was Not the Sole Cause of Oyo’s Collapse
Afonja played a decisive role in the crisis.
His rejection of Oyo authority removed Ilorin from effective imperial control. His recruitment of additional military supporters contributed to the growth of forces that eventually displaced him and transformed Ilorin into a major opponent of Oyo.
But Oyo’s collapse had deeper causes.
Longstanding struggles involving the Alaafin, senior chiefs, military commanders and provincial rulers had weakened the empire’s political cohesion.
Afonja succeeded partly because the imperial system was unable to produce a sufficiently united response to his rebellion.
Later attempts to defeat Ilorin suffered from the same difficulty.
Political rivalry continued to undermine military cooperation even when the survival of the old imperial centre was at stake.
The Conflict Was More Than a Yoruba and Fulani War
The struggle surrounding Ilorin cannot be understood solely as an ethnic conflict between Yoruba and Fulani peoples.
Ilorin’s forces included people from several backgrounds. Yoruba Muslims participated alongside Hausa and Fulani elements. Political interests, military alliances and religious affiliation influenced participation.
Some Yoruba rulers fought other Yoruba forces. Commanders changed alliances, pursued local ambitions and competed for political influence.
Ilorin’s incorporation into the Sokoto Caliphate eventually gave the conflict a wider political and religious significance, but the rebellion had begun within the political crisis of the Oyo Empire itself.
The later wars combined internal rivalry with the expansion of a new emirate whose leadership had become connected to the Sokoto political system.
The Fall Was a Process, Not a Single Event
The Fall of the Old Oyo Empire unfolded over decades.
Political rivalry had already troubled the imperial centre during the eighteenth century. Difficulties developed along the northern frontier. Awole’s reign ended in crisis. Afonja rejected Oyo authority and made Ilorin increasingly independent.
The Muslim military movement later transformed Ilorin. Afonja was killed. Abd al-Salam emerged as ruler. Ilorin developed into an emirate linked to the Sokoto Caliphate.
Oyo launched repeated attempts to recover its position but failed.
As central authority weakened, provincial rulers and new military centres gained greater independence. Rival commanders pursued competing interests.
The final campaign of the mid-1830s ended disastrously.
Oyo-Ile was abandoned soon afterwards.
The empire’s disappearance was therefore the culmination of interconnected political and military crises rather than the result of one battle or one individual.
Conclusion
The Fall of the Old Oyo Empire resulted from the gradual disintegration of a political system that could no longer keep the throne, senior chiefs, provincial rulers and military commanders working towards a common purpose.
Afonja accelerated the crisis but did not create all its causes. His rebellion removed Ilorin from Oyo control, while the later rise of Muslim political power there transformed Ilorin into a formidable regional opponent.

Repeated attempts to reverse that transformation failed.
By the time the final coalition advanced against Ilorin in the mid-1830s, rival political interests had become almost as damaging as the enemy it faced.
The coalition’s defeat left Oyo-Ile exposed. Its inhabitants abandoned the ancient capital around 1836, and Atiba subsequently established the Alaafin’s court at New Oyo.
The collapse of the old imperial centre reshaped the political geography of Yorubaland. Ibadan, Ijaye, New Oyo and other centres grew in importance as populations moved and new military structures developed.
The struggle that followed was no longer simply about restoring the empire that had existed before Afonja. It became a wider contest over the political order that would replace it.
Author’s Note
The collapse of Old Oyo demonstrates how a powerful state can become vulnerable when the relationships holding its political and military institutions together begin to fail. Afonja’s rebellion and Ilorin’s rise were decisive, but they developed within a longer crisis involving rivalry at the political centre, weakening provincial control and repeated failures to maintain united military coalitions. The abandonment of Oyo-Ile around 1836 was therefore the final visible consequence of decades of fragmentation. The political world that followed produced new centres of power and helped shape the nineteenth-century wars that transformed Yorubaland.
