cross until a human sacrifice was performed to appease the angry river. The chosen sacrifice was Nkan. The Olubadan was infuriated at hearing of Nkan's death; he sent an emissary to inform the Alafin of Oyo. Yoruba kings and rulers such as Alake of Egba, Agura of Gbagura, Ooni of Ife, Awujale of Ijebu. Then the Olubadan sent his army to attack the powerful Olowu of Owu and defeated him. The Olowu committed suicide to escape being captured by the Ibadan army. The battle shattered the great Owu kingdom into pieces till today. Some of it remains in the mother town which is the present Orile-Owu in Osun State, while others are in Ogun State, known as Owu Abeokuta and etc.
A part of Ibadan was historically an Egba town. The Egba occupants were forced to leave the town and moved to present-day Abeokuta under the leadership of Sodeke as result of their disloyalty. Ibadan grew into an impressive and sprawling urban center so much that by the end of 1829, Ibadan dominated the Yorùbá region militarily, politically and economically. The military sanctuary expanded even further when refugees began arriving in large numbers from northern Oyo following raids by Fulani warriors. After losing the northern portion of their region to the marauding Fulanis, many Oyo indigenes retreated deeper into the Ibadan environs.
The Fulani Caliphate attempted to expand further into the southern region of modern-day Nigeria, but was decisively defeated by the armies of Ibadan in 1840.
