Time runs, Alaafin Atiba then asked Kunrunmi, Ibikunle and Oyomesi rulling council to allow his Son Odelu to ascend power as next Alaafin whenever he dies. Meanwhile, the tradition instituted by one previous Alaafin and some members of Oyomesi was that whenever any Alaafin dies, his first son should be killed as well. Everybody agreed but Kunrunmi refused, he claimed that tradition should prevail over anything. But he was a party to a confederacy that bolished this tradition before hand.
Different powerful people were sent to Kunrunmi as emissaries to plead to him but to no avail. Kunrunmi chose war instead and challenged Oyo and Ibadan. This turned out to be insult on Alaafin, Bashorun Ogunmola, a very young and fierce warrior in Ibadan, who was once a captive under Kunrunmi preferred they go into war with Kunrunmi. All efforts not to fight with Kunrunmi proved abortive as they know that Kunrunmi was too powerful and Ijaye and his controlled territories were fast growing and Yorubaland may not be able to afford the fall of Ijaye kingdom.
By and large, Ibadan-Oyo military was left with no choice to go into war with Kunrunmi. Bashorun ogunmola and Balogun Ibikunle led the military, launched the battle. Ibadan positioned their armies on the side of river Ọsẹ while Kunrunmi millitary were also securely positioned on the other side of the same river Ọsẹ. Ibadan has been usually sending unarmed Spy 'Alami' to Ijaye to learn Ijaye war strategies, Alami got to know how to copy Ijaye style of beating drum which usually indicates that '' the troop should advance'
Iku ya ju ẹsin lọ, Kunrunmi chose suicide as the only option in 1860. Ijaye fell, an important militarily and economically growing Yoruba regime crashed. One side of the story says, Kunrunmi, magically entered the ground at the river Ose while the other side says, he might have killed himself in the bush but the truth of the matter is that his dead body was nowhere to be found.
After many years, inability of Ijaye Orile town to bounce back to lime-light baffled people of Yorubaland, a certain rumour has it that Ibadan warriors buried two hunchbacks opposite to each other after the war which is preventing the growth of the town back to it's original status
Either the rumour is true or not, Ijaye suffered a stunted growth and United Native African Church came back to the land as the first building to be erected when the town was being re-established in 1895 and the first mosque, according to Prince Olaniyan, was built in 1908. All promised to cast out any possible curse on Ijaye Orile if there is any but till today:
- It is sad that Ijaye Orile, a town that was once holding a military seat of power of the whole Yorubaland cannot even hold an important sitting in Yorubaland anymore.
- Very sad indeed that a community regarded as an important town in 19th century is no more in that class in the 21st century.
- A town that was already welcoming inflow and outflow of about 40,000 people in 1850 when Ibadan, the third most populated City in Africa after Johannesburg and Cairo, was with 60,000 residents.
- A metropolitan town where Rev Bowen himself and his wife, conducted their first Sunday school in Nigeria, lived, died and buried, was not even considered when University of Bowen in Iwo was to be built to immortalize Bowen.
