In the early fourteenth century, decades before the Ottomans became the sole rulers of Anatolia, the Germiyanid beylik stood as a dominant force among the principalities that had emerged in western Anatolia following the demise of the Seljuks (1307). Nonetheless, to date, the exact origins and ethno-cultural background of the Germiyanids remain unclear. This article re-evaluates previous theories and posits that the embryo of what eventually became the Germiyanids formed between the eleventh and thirteenth centuries in the lowlands between Malatya and Lake Van, and that the name “Germiyan” was of Kurdish origin. It also suggests that an intense proto-Yedizi proselytism took place in eastern Anatolia before the Germiyanids migrated to western Anatolia. Beyond its significance to the history of the Seljuks, the Ottomans, the Mongols, and Byzantium, this paper challenges the prevailing narrative that views the emergence of the beyliks as an exclusively Turkic phenomenon and sheds light on the role played by non-Turkic people, including Kurds and Arabs, in their formation.
