Ile-Ibinu Yoruba words (by which name the country was afterward known)
Indigenous name of the Kingdom of Benin
The indigenous name of the Kingdom of Benin is Ile-Ibinu, although it was known as simply Ubunu during its first century of origin.
The Kingdom of Benin, or Ile-Ubinu, emerged in a region formerly named Igodomigodo. At the founding of Benin in the 11th century, the kingdom's inhabitants knew it as Ubinu (related to the word for a center for king's governance), but by the fall of the Ogiso dynasty in the 12th century, it became known as Ile-Ibinu, the name by which it was known for the majority of its history. The name Benin is a Portuguese corruption of the Kingdom's original name.
Alt details: The Portuguese corruption 'Benin' became commonly accepted by locals as the name for Benin City after the 15th century. (Fact check this.) Ubinu was colloquially referred as Bini by its inhabitants. Some regions/tribes referred to the Kingdom as Ubinu up until the 19th century.
