The Sango Koso is the highest and the head of all the Sangos in the world. He is equivalent to a king. In Oyo Empire, it believes that if there is no Sango, there is no Alaafin, if there is no Alaafin there is no Oyo.
Each successive Alaafin can see other Sangos except Sango Koso. It is said that the Alaafin cannot bow for anyone king including Sango Koso and Sango Koso cannot bow for Alaafin. On the arrival of this Sango, the Alaafin by tradition is expected to retire to his chamber as the two cannot reign at the same time.
