Until the emergence of Kassa Hailu, the future Emperor Tewodros II, power was transferred from Ras Ali I to his brother Ras Aligaz. After the death of Ras Aligaz, Ras Wolde Selassie, hereditary ruler of Enderta and overlord of Tigray, became Enderase of the Empire, briefly taking power away from the Wara Sheh rulers. Upon his death, power was transferred to Ras Aligaz's nephew, Ras Gugsa, who in turn transferred power to his sons Ras Yimam, Ras Mariye and Ras Dori.
