Oluaso is the longest reigning Alaafin of Oyo, a good-looking man whose amiable looks contrasted his valor. His immediate predecessor was Alaafin Kori, the king who poisoned himself after an open challenge. Oluaso’s reign, unlike Kori’s, was long and peaceful. He is remembered to have had two set of twins from his wives in the same day. Oluaso had many children, a good number of who rose to stardom by their own merits. He was responsible for erecting over 120 Kobis, a high-thatched gables with porches underneath them. These Kobis served as a place for the Alaafin to view people who greeted him in his courtyards without being fully exposed.
