Yejju Oromo tribe
The Barentu (also Barento/Barentuma) is one of the two moieties of the Oromo people, the other being the Borana. Yejju Oromo is often categorized inside the Barentu branch and other neighboring communities include the Wollo Oromo and the Raya Oromo. Due to Oromo migration to the north, these northern Oromo communities are minorities and they are found in the ethnic Amhara and Tigray dominated regions of northern Ethiopia.
During the 17th century, the Yejju dynasty (more specifically, the Warasek) ruled much of the Ethiopian empire during the Zemene Mesafint or "Age of Princes", changing the official language of Amhara people to Afan Oromo, including inside the court of Gondar. Throughout the era, different ethnic groups, clans and communities made short-term alliances to acquire economic advantage and political power.
Currently, the territories of these northern tip Oromos is officially located inside Amhara Region and Tigray region while the boundaries are rejected by Oromo nationalists, including the Oromo Liberation Front
