History. In the 14th century several autonomous towns (Amasya, Tokat, Sivas) were established, despite the continued Seljukid-Mongol rule in central Asia Minor. When the Ilkhanid ruler Ebu Said died in 1335, administration of Asia Minor was entrusted to his former governor Eretna Bey, an Uyghur. Eretna Bey ultimately declared independence, seeking the protection of the Mamluks, who were rivals of the Ilkhanids. He captured the area around Sivas-Kayseri, eventually establishing an emirate of Eretna, which grew stronger during the rule of his son, Mehmed  Bey. In 1381 Kadı Burhaneddin a kadı in Kayseri who was also appointed vizier to represent the emirate of Eretna in that town, replaced the Eretnid as ruler of Sivas and also captured Amasya and Tokat. His principality managed to resist interference in central Anatolia from both the Akkoyunlus and the Ottomans until it collapsed with his death in 1398. Administrative divisions.
