The Ọ̀yọ́ war commander whose revolt broke the empire, the Fulani scholar whose community he armed, and how Ìlọrin passed from a Yoruba town under a Yoruba general to an emirate of the Sokoto Caliphate.
Àfọ̀njá was Àrẹ̀ Ọ̀nà Kakanfò, the field commander of the Ọ̀yọ́ provincial army, and the man who led the mutiny that ended Aláàfin Awólẹ̀'s reign and with it the unity of the empire. He then made Ìlọrin, his own base, independent, and to hold it he armed and sheltered a population of Muslims and of enslaved Hausa people fleeing Ọ̀yọ́ households. Within a decade that force had killed him and Ìlọrin had become an emirate of the Sokoto Caliphate under the descendants of the Fulani scholar he had invited in. The sequence is the hinge on which nineteenth-century Yoruba history turns, and it is also where Yoruba historiography is at its most polemical, because Àfọ̀njá is remembered in Ọ̀yọ́ tradition as the man who destroyed the country and in other framings as a rebel against a king who had tried to kill him.
The Kakanfò was the supreme field commander of the Ọ̀yọ́ army, an office held by a non-royal and, by convention, resident outside the capital. The holder was expected to win or die: tradition attached to the title an obligation not to return defeated. Concentrating military command in a provincial figure who could not become king and was not resident under the Aláàfin's eye worked while the centre was strong. When the centre weakened it produced exactly the crisis of 1796. Johnson lists the holders of the title and notes that Látóòsà of Ìbàdàn was the last to hold it in the nineteenth-century sequence .
Àfọ̀njá's dates are given as approximately the 1750s to somewhere between 1813 and 1824, and the death date is genuinely disputed in the sources; see below. He came from the line that held the Yoruba bàálẹ̀-ship at Ìlọrin: his great-grandfather Laderin is credited with founding the town, followed by Pasin, who was exiled and killed by Bàṣọ̀run Gàhá, then Alugbin, and then Àfọ̀njá . That inheritance matters, because Ìlọrin was his own town before it was his garrison.
He competed for the Ọ̀yọ́ throne against Awólẹ̀ in 1789 and lost narrowly, and was afterwards made Kakanfò; one account has him demanding and taking the title after the death of Ọ̀yábí, the Kakanfò who had helped Abíọ́dún destroy Gàhá . The relationship with Awólẹ̀ was poisoned from the start.
The break came, in Johnson's account, when Awólẹ̀ ordered the army against Ìwẹ̀rẹ̀, an order the chiefs read as designed to destroy them, since the town was reputedly impregnable and was connected to a former Aláàfin's maternal line . Àfọ̀njá, allied with Bàṣọ̀run Àṣàmú and the Ọ̀wọ̀ta of Ọ̀yọ́, turned the army on the royal party, besieged the capital, and sent the empty covered calabash that constitutionally required the king's death . Awólẹ̀ pronounced his curse and took poison, and Àfọ̀njá is one of the named targets of that curse.
Àfọ̀njá then held Ìlọrin as an independent power and other provinces followed, which is the point at which the empire ceased to function as one state.
To hold Ìlọrin against Ọ̀yọ́, Àfọ̀njá needed manpower he did not have, and he found it by opening the town. He offered freedom and protection to Muslims and to enslaved people facing persecution in Ọ̀yọ́ country if they would come to Ìlọrin . In practice this meant Hausa people held in slavery in Ọ̀yọ́ households, many of them Muslim, who now had a place to run to and a commander who would arm them. The military logic is obvious and so is the social consequence: it created inside Ìlọrin an armed body with its own religious identity and no loyalty to Ọ̀yọ́ institutions.
He invited as their religious head Ṣẹ́hù Àlímì, whose name appears also as Shaykh Sálih and Salih Janta, a Fulani Islamic scholar who had been preaching in Ọ̀yọ́ country and had met opposition there . Àlímì came to Ìlọrin with his followers and his own household, and Johnson's account and the Ìlọrin accounts agree that his arrival transformed the town's balance. Alongside him, Àfọ̀njá invited Ṣọlágbérù, a wealthy Yoruba Muslim, who settled at Òkè Sùnà on the outskirts with converts drawn from several communities . Òkè Sùnà was therefore a Yoruba Muslim quarter distinct from the Fulani and Hausa element, and that distinction becomes important.
The armed body took the name jamaa, from Arabic and Hausa usage for the community, and its members were marked distinctively . Àfọ̀njá could not control them. Accounts describe them raiding and plundering, and when Àfọ̀njá moved to disband them, they moved first: attacked his compound, and killed him . Accounts state that he was killed with arrows and spears in numbers and that his body was burned . Ṣọlágbérù, appealed to for help, did not come, and the explanation offered in the tradition is that as a Muslim chief he would not fight Muslims on behalf of a man who had not converted . Ṣọlágbérù was himself killed later by Àlímì's son .
Sources give Àfọ̀njá's death variously as around 1813, around 1823, and in early 1824 . The spread is not trivial and it is not resolvable from the material available here. Popular Nigerian sources state one or another of these dates with confidence and without indicating that the others exist. This corpus records the disagreement rather than choosing. The order of events is secure: revolt against Awólẹ̀ in 1796, Ìlọrin's independence, the opening of the town and the arrival of Àlímì and Ṣọlágbérù, the loss of control of the jamaa, and Àfọ̀njá's killing, followed by the emirate.
Ṣẹ́hù Àlímì died about 1820 . His son Abdulsalami, also Abd al-Salam, was acclaimed by Ìlọrin's Muslims as the first Emir, pledged allegiance to the Sokoto Caliphate, and ruled to 1842; the emirate was placed under the authority of Gwandu rather than Sokoto directly . He was succeeded by his brother Shitta, who ruled to 1860 . The throne remained with Àlímì's descendants.
Ìlọrin as an emirate then became the northern military pressure on Yorubaland for the rest of the century. Its forces burned Ọ̀yọ́-Ilé, the old imperial capital, forcing its final abandonment and the move to New Ọ̀yọ́ under Àtìbà . Ìlọrin cavalry, operating on the open savanna where horses were effective, drove the Ọ̀yọ́ population south into the forest, and the refugee resettlement that followed created or vastly expanded Ìbàdàn, Ìjàyè, Abẹ́òkúta and New Ọ̀yọ́. The whole nineteenth-century Yoruba political map is downstream of this.
The Ìlọrin advance was stopped at Òsogbo, where an Ìbàdàn-led force defeated an Ìlọrin army, conventionally dated to the 1830s or early 1840s. That battle fixed the southern limit of Sokoto expansion and is the reason Ìlọrin is the frontier rather than the midpoint of Islamic political authority in Yorubaland .
In the Ọ̀yọ́ tradition Johnson transmits, Àfọ̀njá is the traitor whose ambition destroyed the country, and Awólẹ̀'s curse is the frame. That is one community's verdict, recorded by a partisan of that community, and it has been enormously influential because Johnson's book was the schoolbook.
The countervailing points are documented and should be stated. Awólẹ̀ had, on the accounts available, sent the army on an errand the chiefs believed was meant to kill them, which is what the Ọ̀yọ́ constitution's rejection mechanism existed to answer. Àfọ̀njá used a constitutional instrument, the calabash, not an innovation. His subsequent decision to arm fugitive enslaved people was a military expedient of a kind commanders take when losing, and it was also, in effect, an emancipation, which is why he was able to raise a force at all.
What is not in doubt is the outcome. Àfọ̀njá lost control of the instrument, was killed by it, and the town his family had held for four generations passed permanently out of Yoruba dynastic hands into an emirate that then made war on Yorubaland for seventy years. He is a figure of consequence rather than a figure of blame or vindication, and the Yoruba argument about him is really an argument about the Ọ̀yọ́ constitution and about Islam's place in Yoruba politics, conducted through a biography.
