[12] Partial or full Turkification of Anatolian Greeks dates back to the early 1100s, as a result of living together with neighboring Turks.

"[14] Daniel Panzac elaborates that 'Karaman Greeks' became fully linguistically and culturally Turkified during the reign of Murad III (r. 1574–1595), and some of them had also converted to Islam.

[15] The Ottoman explorer Evliya Çelebi, who visited the Karamanlides and experienced their lifestyle, wrote that they spoke with an authentic Turkish accent but used Greek and Latin words as well.

They printed books, particularly the bible, in Turkish language and chanted hymns in Karamanlidika, despite their neighborhoods also having Greek-speaking communities.

"[18] Another Karamanlis author named Iosepos Moesiodax, wrote in his Paedagogy (1779) that "the need of our public demands good Turkish, because it is the dialect of our Rulers.

[...] it is an indisputable fact [...] that in a great part of Anatolia even the public worship of the Greeks is now performed in the Turkish tongue.The German orientalist Franz Taeschner (1888–1967) observed that the Karamanlides were completely Turkified, with the exception of their religion.

The British historian Edwin Pears (1835–1919), who lived in Turkey for approximately 40 years, wrote that the Karamanlides were originally Greeks, who had lost their native language and spoke Turkish.

It is an indisputable fact, that the language of their oppressors has long since almost universally prevailed, and that in a great part of Anatolia even the public worship of the Greeks is now performed in the Turkish tongue.Similarly, the British scholar David George Hogarth (1862–1927) attributed the Turkification of the Karamanlides to oppression; in 1890 while visiting Lake Eğirdir, he wrote that "the Moslems were eating them up.

[25] It is known that some Karamanlides lived in İznik as well as Bursa, İzmit and Yalova, and they left Turkish inscriptions written in Greek letters.

[32] Upon their arrival in Greece, Karamanlides faced many instances of discrimination by the local Greek population "because they spoke the language of the age-old enemy of Hellenism"; sometimes even taunted with the allegation that they were of Turkish background.
