For centuries, thousands of Greek-speaking people identified as Turks through the Ottoman millet system.

In short: In the Ottoman Empire, religious affiliation defined identity far more than ethnicity or language. This system led to the emergence of Greek-speaking Muslims, communities of Greek origin who adopted Islam and, over generations, integrated into the Turkish mainstream, often retaining their native Greek dialects while identifying as Turks.

The phenomenon of Greek-speaking Muslims, or Grecophone Muslims, arose through centuries of contact between the Byzantine Empire and Islamic caliphates, and later under Ottoman rule. Conversion was often driven by pragmatic incentives within the Ottoman state. Non-Muslims were subject to heavy taxes like the jizya and haraç, which were waived upon conversion. Furthermore, the Ottoman legal structure favored Muslims, as Islamic courts held supremacy over non-Islamic ones, effectively barring non-Muslims from defending their own cases. Beyond these pressures, conversion offered paths to advancement in the military and government bureaucracy.

The Ottoman millet system categorized subjects by religion rather than ethnicity. Consequently, once a Greek Christian converted to Islam, they were legally and socially absorbed into the Muslim community. This process was sometimes accelerated by practices like the devşirme, where Christian boys were recruited and trained for elite roles, or through voluntary conversion for social and economic mobility. By the late 19th and early 20th centuries, this identity shift was solidified by political events, including the Greco-Turkish War of 1897 and the subsequent 1923 population exchange, which categorized people as 'Turks' or 'Greeks' based strictly on religion.

Today, many descendants of these communities, such as the Pontic Greek Muslims or the Vallahades of Macedonia, remain in Turkey. While many have fully assimilated into Turkish culture and language, others have preserved their ancestral Greek dialects, such as Romeïka or Cretan Greek, even while identifying as Turks. In some cases, such as in the Dodecanese islands of Kos and Rhodes, small communities of Greek-speaking Muslims persist, reflecting a complex history where language and ethnicity were often secondary to the religious and political structures of the time.
