Eretnid dynasty
The Eretnids were a dynasty that ruled a state spanning central and eastern Anatolia from 1335 to 1381. The dynasty's founder, Eretna, was an Ilkhanid officer of Uyghur origin, under Timurtash, who was appointed as the governor of Anatolia. Some time after the latter's downfall, Eretna became the governor under the suzerainty of the Jalayirid ruler Hasan Buzurg. After an unexpected victory at the Battle of Karanbük, against Mongol warlords competing to restore the Ilkhanate, Eretna claimed independence declaring himself the sultan of his domains. His reign was largely prosperous earning him the nickname Köse Peygamber.
