Zabin Alaafin 
The Oyo Empire was not a purely hereditary monarchy, nor was it an absolute one. The Oyo Mesi selected the Alaafin.  He was not always closely related to his predecessor, although he did have to be descended from Oranmiyan, a son of Oduduwa, and to hail from the Ona Isokun ward (which is one of the three royal wards).  At the beginning of the Oyo Empire, the Alaafin's eldest son usually succeeded his father upon the throne. This sometimes led the crown prince, known as the Aremo, to hasten the death of his father. In order to prevent this occurrence, it became traditional for the crown prince to be made to commit ritual suicide upon his father's death. Independent of the succession, the Aremo was quite powerful in his own right. For instance, by custom the Alaafin abstained from leaving the palace, except during the important festivals, which in practice curtailed his power. By contrast, the Aremo often left the palace. This led the noted historian S. Johnson to observe: "The father is the king of the palace, and the son the king for the general public". The two councils which checked the Alaafin had a tendency to select a weak Alaafin after the reign of a strong one to keep the office from becoming too powerful.
