The Umuezechima migration to Onitsha

Overview

Followers of Eze Chima left Benin after a quarrel with the court, one tradition says with the Queen Mother over farmland or tribute, and fought Benin’s armies as they went. Branches founded the Umuezechima towns west of the Niger, among them Issele-Uku, Onicha-Olona, Onicha-Ugbo and Obior. Chima died before the crossing, and his son Oraeze led the rest over the river to found Onicha Mmili, Onitsha.^[1],[2]Disputed

One account dates the migration to the reign of Oba Esigie in the 16th century; another places Onitsha’s founding between 1630 and 1680.
