オロモ人
The Gada system has been inscribed by UNESCO as Intangible Cultural Heritage since 2016. It is the brainchild of Oromo from the Madda Walabu district of Oromia. Oromo people regarded the system as their common heritage and as a major part of their cultural identity. It is the system with which the Oromo people have been governing themselves in a democratic way for centuries.
