Onisile was an Alaafin of the Yoruba Oyo Empire during the eighteenth century. Onisile succeeded as ruler of the Oyo Empire. According to tradition, Onisile was both a great warrior and artistic. He reportedly had seven silver doors made to the seven entrances of his sleeping apartment. Onsile's downfall reportedly came after he experimented with a plant (the 'sun leaf') that supposedly attracted lightning. He was struck by lightning and paralysed, leading the Oyo Mesi (the principal counselors of state) to reject him as ruler. He was succeeded by Labisi.
