Odarawu
Odarawu was an Alaafin of Oyo, who was on the throne for a short period of time. He was considered a man of bad temperament. According to Oyo legend his bad temper led him to being removed as king and also served as educational warning and lesson to future kings on character development.
Odarawu's major battle was also his first and last blunder on the throne. During his reign, he ordered the destruction of a town called Ojo-segi for the trite reason of being disrespected in the market by a trader in Ojo-segi. Subsequently, the Oyo masses found him unfit to be king and he was asked to commit suicide.
