Yoruba
Historically the Yoruba people have been the dominant group on the west bank of the Niger. Their nearest linguistic relatives are the Igala who live on the opposite side of the Niger's divergence from the Benue, and from whom they are believed to have split about 2,000 years ago. The Yoruba were organized in mostly patrilineal groups that occupied village communities and subsisted on agriculture. From approximately the 8th century A.D., adjacent village compounds called ile coalesced into numerous territorial city-states in which clan loyalties became subordinate to dynastic chieftains. Urbanization was accompanied by high levels of artistic achievement, particularly in terracotta and ivory sculpture and in the sophisticated metal casting produced at Ife.
The Yoruba paid (and a number of them around the world still pay) tribute to a pantheon composed of an impersonal Supreme Deity, Olorun, and 400 lesser deities who perform various tasks. Oduduwa is regarded as both the creator of the earth and the ancestor of the Yoruba kings. According to one of the various myths about him, he founded Ife and dispatched his sons and daughters to establish similar kingdoms in other parts of what is today known as Yorubaland.
