Yakub I (died c.1340) was the founder of the beylik of Germiyan, located in western Anatolia around Ktahya. Although Germiyan revolted against Mesud II (r.128497, 13038), the Sultan of Rum, Yakub accepted vassalage under Kayqubad III (r.12981302). The Sultanate of Rum disintegrated shortly after. At that point, Yakub's realm extended as far east as Ankara and incorporated various towns taken from the Byzantine Empire and the Catalan Company. Yakub was the suzerain of many of his neighbors, and his reign was described as economically prosperous by contemporary historians. He was succeeded by his son Mehmed, nicknamed Chakhshadan.== Background ==During the 11th century, much of West Asia was subject to Seljuk rule. A branch of the Seljuk dynasty formed the Sultanate of Rum, an Islamic state in Anatolia, which saw its height from the late 12th century to 1237. The Germiyan first appeared in 1239 under Kaykhusraw II's rule of the Sultanate of Rum. Muzaffar al-Din, Yakub I's paternal grandfather, was tasked with subduing Baba Ishak's rebellion in the area around Malatya.
