Оромо
Barento Oromo people are one of the two main moiety of the Oromo people in the Oromia Region of Ethiopia. Between the twelfth and fifteenth centuries, the Borana Oromo and Barentu Oromo people had differentiated from the confederation. The Barento people thereafter expanded to the eastern regions now called Hararghe, Arsi, Wello, and northeastern Shawa. The Borana people, empowered by their "Gadda" political and military organization expanded in the other directions, regions now called western Shawa, Welega, Illubabor, Kaffa, Gamu Goffa, Sidamo and in the 16th-century into what is now northern Kenya regions. The Borana and Barentu groups are sometimes referred to as two early era moieties of the Oromo people.
