The political head of the Old Oyo Empire was called the Alaafin. This was the supreme ruler who had the final say in all matters relating to governance, justice, and religious affairs. The Alaafin was considered the custodian of the customs and traditions of the people of the Old Oyo Empire and was responsible for maintaining peace and stability within the kingdom. The Bashorun, Aremo, and Oyomesi were also important officials in the Oyo Empire, but the Alaafin held the highest political authority.
