The ubuhake and uburetwa system, and its exploitation by both Tutsi Mwamis and by European colonial powers, is one source of antagonism between the Hutu and Tutsis. Many of the recent events in both countries can be traced to this historical tension, including the 1994 Rwandan genocide.

A hereditary king (called the kabaka) and a landed nobility provided a structure similar to those in northern Rwanda at the time of the arrival of European explorers.
