The ancient Anatolian peoples spoke the now-extinct Anatolian languages of the Indo-European language family, which were largely replaced by the Greek language from classical antiquity and during the Hellenistic, Roman, and Byzantine periods. Major Anatolian languages included Hittite, Luwian, and Lydian, while other, poorly attested local languages included Phrygian and Mysian. Hurro-Urartian languages were spoken in the southeastern kingdom of Mitanni, while Galatian, a Celtic language, was spoken in Galatia, central Anatolia. The Turkification of Anatolia began under the Seljuk Empire in the late 11th century and continued under the Ottoman Empire between the late 13th and early 20th centuries and under today's Republic of Turkey. However, various non-Turkic languages continue to be spoken by minorities in Anatolia today, including Kurdish, Neo-Aramaic, Armenian, Arabic, Laz, Georgian and Greek. Other ancient peoples in the region included Galatians, Hurrians, Assyrians, Hattians, Cimmerians, as well as Ionian, Dorian and Aeolic Greeks.
