The Eyalet of Rûm (; ; originally Arabic for Eastern Roman Empire), later named as the Eyalet of Sivas (; ),
Rûm was the old Seljuk Turkish designation for Anatolia, referring to the Eastern Roman Empire, and in European texts as late as the 19th century the word Rûm (or Roum) was used to denote the whole of central Anatolia, not just the smaller area comprising the Ottoman province (see Sultanate of Rum).
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, a Uyghur. Eretna Bey ultimately declared independence, seeking the protection of the Mamluks, who were rivals of the Ilkhanids.
