Eretna

The Eretnids were a sultanate that straddled central and eastern Anatolia from Sivas to Kayseri between 1335 and 1381, rising from the Ilkhanate. Its founder Eretna was an officer of Uyghur origin who served the Mongol governor Timurtash and became viceroy of Anatolia; in 1337 he governed as an Ilkhanid, then Jalayirid, vassal.

After defeating Mongol warlords at Karanbük in 1343 he declared independence and became sultan. His rule earned him the nickname Köse Peygamber, the beardless prophet. His son Muhammad I was deposed and restored in a feud with his brother Jafar, and murdered by his emirs at Kayseri in 1365.

The child sultans Ala al-Din Ali and Muhammad II Chelebi were dominated by their vizier Kadı Burhan al-Din. Ali died of plague in 1380; within a year Burhan al-Din deposed Muhammad II and seized the throne, ending the dynasty and its state.
