Abiru

Abiru, meaning royal ritualists, were the king’s secret advisers in Rwanda. They guarded the ubwiiru, an esoteric code of kingship, and formed a priestly council that could appoint, advise, or remove a king. Because early Rwandan history blends myth with fact, exact details are hard to pin down.

The Abiru came from a hereditary class called the Abatsobe, part of the broader Tutsi ethnicity. The first Abiru trace back to Kigwa (The Landed), a divine being who descended from heaven and became one of Rwanda’s first god-kings. To legitimize his rule, he created court musicians and ritual specialists—the first Abiru—who remained a powerful institution for generations.

As a secret society, they advised the king on political matters and watched his ritual and political fitness. They could depose unworthy kings and name successors using their esoteric rules. In Burundi there is a similar status among the Ganwa.
