There were series of inter-clannish clashes with the Edo immigrant that arrived at Irrua as far back as 1463, culminating in a protracted war. These immigrants were not satisfied with dominating the humble folks they met and treated like slaves or bush men, but were out to eliminate them. For years, the aborigines bore the crushing treatment the immigrants meted out to them, but they finally had to quit. They left their land and homes and escaped with what they could take with them into the jungle and settled in the present day Opoji.

The greedy strangers still sought the fugitives out and continued to harass them from Irrua, for years, until they decided to fight back. They put together a splendid body of warriors under indomitable leaders like Akpokhio, Onugbenugbe and Ohiabhidale.  Under their leadership, the erstwhile fugitives began to lead retaliatory sorties to Irrua, and this very much angered Ogbeide  the Terrible, who had just come to the throne of Irrua. Ogbeide wanted their heads. He used one of their friends in Irrua to trick them into one house where they were trapped and rounded up, tried and be-headed.
