Obalokun

Obalokun established diplomatic and commercial relations with Portuguese traders along the coast. He allowed European merchants to enter Oyo territory and trade for slaves, ivory, and pepper. This opened Oyo to the Atlantic slave trade, which would become a major source of wealth and power for the empire.

Obalokun is credited with significantly expanding and reorganizing Oyo's cavalry, importing horses from the north. This military reform made Oyo's army one of the most powerful in the region, enabling future conquests and the empire's expansion into a major power.
