In the old Oyo empire, the Ajele were responsible for ensuring the good governance of the district and ensuring the safety of the trade routes. They were not responsible for mobilizing the army or being the head of the army.
The Ajele were appointed by the Alaafin (the king of the Oyo empire) to serve as his representatives in the provinces. They were responsible for overseeing the administration of the district, including the collection of taxes, settling disputes, and maintaining law and order. They were also responsible for protecting the trade routes within their district, which were crucial for the economic well-being of the empire. The Ajele played an important role in maintaining the stability and prosperity of the Oyo empire.
