Germiyanids

The Germiyanid beylik was a Turkoman principality centered on Kütahya in western Anatolia. In 1337 Yakub I ruled a realm established as the Seljuk Sultanate of Rum dissolved.

In 1381 Suleiman married his daughter Devletşah Hatun to the Ottoman prince Bayezid, giving Kütahya and much of the beylik to the Ottomans as her dowry. Bayezid imprisoned Yakub II in 1390; Yakub escaped to Timur and recovered his lands after the Battle of Ankara in 1402. He died without a male heir in 1429, leaving Germiyan to the Ottoman sultan Murad II in his will.
