Edo people

According to tradition, the original people and founders of the Ẹdo Empire and the Edo people, were ruled by the kings known as the Ogiso (meaning King of the sky) dynasty who called the land Igodomigodo. Igodo, the first Ogiso, wielded much influence and gained popularity as a good ruler. He died after a long reign and was succeeded by Ere, his eldest son. A battle for power soon erupted between the wife of the last Ogiso and prince Ekaladerhan, son of the last Ogiso. Prince Ekaladerhan was framed by his father's wife and sentenced to death. The men sent to kill him, however, released him at Ughoton. The exiled prince made his way to where he changed his name to Izoduwa, meaning "I have found prosperity". It was during this period of confusion in Benin that the elders, led by Chief Oliha, mounted a search for the banished Prince Ekaladerhan – whom the Ife people now called Oduduwa.

The exiled Ekaladerhan, now Oduduwa, refused to come to Benin because of how he was treated, having found out that he was not killed. He devised to send one of his sons, Oramiyan. He refused to return from Ile-Ife but sent his son Ọranmiyan to become king in his place. Prince Ọranmiyan took up residence in the palace built for him at Uzama by the elders, now a coronation shrine. Soon after he married a beautiful lady, Ẹrinmwide, daughter of Osa-nego, the ninth Enogie of Egor. He and Erinmwide had a son. After some years he called a meeting of the people and renounced his office, remarking that the country was a land of vexation, Ile-Ibinu, and that only a child born, trained, and educated in the arts and mysteries of the land could reign over the people. The country was afterward known by this name. He caused his son born to him by Ẹrinmwide to be made King in his place and returned to Benin land. After some years in Ife, he left for Benin, where he also left a son behind upon leaving, and his son Ajaka ultimately became the first Oba of Benin of the present line, while Ọranmiyan himself was reigning as Ọọni of Ifẹ. Therefore, Ọranmiyan of Ife, the father of Ẹwẹka I, the Ọba of Benin, was also the father of Ajaka, Alaafin of Ọyọ. Ọọni of Ifẹ. Ọba Ẹwẹka later changed the name of the city of Ile-Binu, the capital of the Benin kingdom, to "Ubinu." This name would be reinterpreted by the Portuguese as "Benin" in their own language. Around 1470, Ẹwuare changed the name of the state to Ẹdo. This was about the time the people of Ọkpẹkpẹ migrated from Benin City. Alternatively, the Yoruba nation has a different conception of Oduduwa. According to Yoruba tradition, because of his power and military might, he was able to defeat the enemies invading Benin and that is why the people of Benin made him the King or Ọba of Benin. In any case, it is agreed upon by both the Yoruba and the Edo that Oduduwa sent his son Prince Oranmiyan of Ife to rule Benin City and founded the Oba dynasty in Benin City.

Benin imperialism was started in the last decade of the thirteen century by Oba Ewedo.
