THE ONITSHA KINGDOM
The Onitsha Kingdom, which was originally inhabited by Igbo, was founded in the 16th century by Igbo migrants from Benin. Later groups like the Igala and Igbo traders from the hinterland, settled in Onitsha in the 18th century. Another Igbo kingdom to form was the Arochukwu kingdom, which emerged after the Aro-Ibibo wars from 1630-1720.
The Aro Confederacy dominated Southeastern Nigeria with pockets of influence in Equatorial Guinea and Cameroon.
