Ajagbo
Ajagbo was an Alaafin of the West African Oyo Kingdom, who was on the throne for a remarkable length of time. He was notable for introducing the title of Kakanfo, similar to a field marshal in Oyo. He was also known by Oyo neighbours as a warlike king who sent armies to destroy towns in the popo country, Ile Olopa and his maternal town Ikereku-were.
