Kos. These communities were formed prior to the area becoming part of Greece in 1948, when their ancestors migrated there from Crete, and their members are integrated into the local Muslim population as Turks today. Language Some Grecophone Muslims of Crete composed literature for their community in the Greek language, such as songs, but wrote it in the Arabic alphabet. although little of it has been studied. Today, in various settlements along the Aegean coast, elderly Grecophone Cretan Muslims are still conversant in Cretan Greek. Many in the younger generations are fluent in the Greek language. Often, members of the Muslim Cretan community are unaware that the language they speak is Greek. Frequently, they refer to their native tongue as Cretan (Kritika or Giritçe) instead of Greek. Religious practice Grecophone Cretan Muslims are Sunnis of the Hanafi school, with a highly influential Bektashi minority who helped shape the folk Islam and religious tolerance of the entire community. Epirote Muslims Muslims from the region of Epirus, known collectively as Yanyalılar (singular Yanyalı, meaning "person from Ioannina") in Turkish and Τουρκογιαννιώτες Turkoyanyótes in Greek (singular Τουρκογιαννιώτης Turkoyanyótis, meaning "Turk from Ioannina") arrived in Turkey in two waves of migration, in 1912 and after 1923. After the exchange of populations, Grecophone Epirote Muslims resettled themselves in the Anatolian section of Istanbul, especially the districts from Erenköy to Kartal, which had previously been populated by wealthy Orthodox Greeks. Although the majority of the Epirote Muslim population was of Albanian origins, Grecophone Muslim communities existed in the towns of Souli, Margariti (both majority-Muslim), Ioannina, Preveza, Louros, Paramythia, Konitsa, and elsewhere in the Pindus mountain region. The Greek-speaking Muslim populations who were a majority in Ioannina and Paramythia, with sizable numbers residing in Parga and possibly Preveza, "shared the same route of identity construction, with no evident differentiation between them and their Albanian-speaking cohabitants." Hoca Sadeddin Efendi, a Greek-speaking Muslim from Ioannina in the 18th century, was the first translator of Aristotle into Turkish. Some Grecophone Muslims of Ioannina composed literature for their community in the Greek language, such as poems, using the Arabic alphabet.
