Germiyan

The Germiyanids were a Turkoman dynasty that ruled western Anatolia from Kütahya from around 1300 to 1429. The Germiyan tribe moved west under Mongol pressure; when the Sultanate of Rum dissolved, Yakub I made the beylik sovereign.

Yakub I ruled in 1337, his court a centre of learning where Persian works were translated into Turkish. His successors included Mehmed and Süleyman; Süleyman married his daughter Devletşah Hatun to the future Bayezid I with a dowry that surrendered much of the realm, including Kütahya.

Yakub II was imprisoned by Bayezid in 1390 but fled to Timur and was restored after the Battle of Ankara in 1402. Having no sons, he bequeathed the beylik to Murad II on his death in 1429, and Germiyan passed peacefully into the Ottoman Empire.
