The spiritual, or supernatural, king is represented by the Royal Drums. These are regalia called Mujaguzo and, as they always exist, the Buganda at any time will always have a king. Mujaguzo, like any other king, has his own palace, officials, servants, and palace guards.

The material, human prince has to perform special cultural rites on the Royal Drums before he can be declared king of the Kingdom of Buganda. Upon the birth of a royal prince or princess, the Royal Drums are sounded by drummers specially selected from a specified clan as a means of informing the subjects of the kingdom of the birth of new member of the royal family. The same Royal Drums are sounded upon the death of a reigning king to officially announce the death of the material king.
