Bini people

The Edo or Bini people are an ethnic group primarily found in Edo State, And Spread Across Delta state, Ondo State, Rivers state Nigeria. They speak the Edo language and are the descendants of the founders of the Benin Empire. They are closely related to other ethnic groups that speak Edoid languages, such as the Esan, the Afemai and the Owan.

The name "Benin" (and "Bini") is a Portuguese corruption, ultimately from the word "Ubinu", which came into use during the reign of Oba Ewuare the Great, c. 1440. "Ubinu" was used to describe the royal administrative centre or city or capital proper of the kingdom, Edo. 'Ubinu' was later corrupted to 'Bini' by the mixed ethnicities living together at the centre; and further corrupted to "Benin" around 1485 when the Portuguese began trade relations with Oba Ewuare. See Oba of Benin.
