According to some sources, mainly Greek, Evrenos son of Isa (Jesus) Bey Prangi came from a family of Byzantine origin which transferred its alliance to the Turkish Karasi rulers of western Anatolia and had converted to Islam in the 14th century. Other scholars, generally Turkish, claim that the family was of ancient Turkish origin. Certainly Gazi Evrenos was first mentioned as a middle ranking bey.
