Greek Muslims
Greek Muslims, also known as Grecophone Muslims, are Muslims of Greek ethnic origin whose adoption of Islam (and often the Turkish language and identity in more recent times) dates either from the contact of early Islamic caliphates with the Byzantine Empire or to the period of Ottoman rule in the southern Balkans and Anatolia. In more recent times, they consist primarily of descendants of Ottoman-era converts to Islam from Greek Macedonia (e.g., Vallahades), Crete (Cretan Muslims), and northeastern Anatolia (particularly in the regions of Trabzon, Gümüşhane, Sivas, Erzincan, Erzurum, and Kars).
