During the 16th century, the Uzea War occurred. This war was between the Uromi Kingdom and the Benin Kingdom. The war lasted from 1502 to 1503, and resulted from a refusal of friendship from Oba Ozolua of Benin by Onojie Agba of Uromi. The war ended at the town of Uzea, when both leaders were killed. However, in peaceful times Esan kingdoms would loan soldiers to the Benin Kingdom, such as during the Idah War of 1515-1516, and the sacking of Akure in 1823.
