The Germiyanids ( or Germiyan Beyliği) was a prominent Anatolian beylik established by the Oghuz Turkish tribes (probably the Afshar tribe) after the decline of Sultanate of Rûm. However, while the beylik was always mentioned as Turkoman or Oghuz Turkish, the population consisted of Turks and Yezidi Kurds, brought by the Seljuks from the east of Malatya to western Anatolia as militia guards against the threatening Turkish tribesmen. Origins According to Agoston and Masters Germiyanoğulları were Turkomans who had immigrated to the west because of Mongol pressure in the second half of the 13th century. The Germiyanids were of Afshar branch of Oghuz Turks. Germiyanids likely came from Kerman or Fars Province, perhaps headed west with Khwarazmshahs. After the death of Jalal ad-Din Mingburnu, they remailed in Malatya area for a while, then moved to Kütahya, where they established the beylik. According to Middle East historian Petry, the Germiyans were a Turco-Kurdish dynasty. However, cultural historian Cemal Kafadar states the ethnic make up of the dynasty is too complex for a simple straightforward interpretation. History For a brief period in the second half of the 14th century, Germiyan Dynasty was second only to Karamanid Dynasty in its rising power. But they were later taken over by the neighboring Osmanoğlu dynasty, who were to found the Ottoman Empire later. Germiyans played a crucial role in settling Turkish populations along the coastal regions of the Aegean Sea, the founders of the Beyliks of Aydin, Sarukhan, İnançoğlu and Menteşe having started out as Germiyan commanders. They rebelled against the central power in 1283, upon the execution of the sultan Kaykhusraw III by the Mongols, and placing of Mesud II on the Seljuq throne. The struggle between combined Mongol-Seljuq forces based in Konya and the rebel forces of Germiyan continued until 1290. An agreement could only be reached in 1299, upon which the Germiyan Dynasty also entered into possession of Ankara. When the Ilkhanid governor Emir Çoban took over Anatolia in 1314, they declared allegiance and concentrated on raids towards the regions to their west. Their western offshoots that were the Beyliks of Menteşe, Aydin, Ladik, Sarukhan and Karasi were all subject to the Germiyan in the early periods of their foundation, while the Beyliks of Sâhib Ata and Hamidids to the south had to rely on them for protection against attacks from the Karamanids. As for the northern regions of Anatolia, Byzantine sources
