Edo and Yoruba in Nigeria

The term "Yoruba" refers to a language and various ethnic groups in a region in West Africa stretching from the middle Niger to the Atlantic coast, between Nigeria and Benin. Oduduwa, the original Yoruba divinity, ruled over the mythical city of Ife, where the world was created. He is the ancestor of all the sovereigns in the Yoruba kingdoms (Oyo, Owo, Ketu, etc.) and of the Edo kingdom in Benin after the fall of the Ogiso dynasty.
