The dynasty's founder, Eretna, was an officer of Uyghur origin in the service of Timurtash, the Ilkhanid governor of Anatolia. After his master unsuccessfully revolted in 1327 to ally with the Mamluks in response to the fate of his father Chupan, IlkhanAbu Said appointed Eretna a governor of Rum. Eretnids were able to establish their own beylik when the khan died in 1335[1]. After Eretna's death, his lands were nibbled away by the Ottomans in the west and Aq Qoyunlu in the east. The Beylik's last ruler, Muhammad II, was replaced by his vizierKadı Burhaneddin who reigned in the same region for another eighteen years, a period some sources consider as a continuation of the same institutional structure, while other sources treat as being separate.
