What was the name of the area in the highlands of central Anatolia ruled by Deiotarus?
Galatia Ancient Galatia ( ; Greek: Γαλατία , Turkish: "Galatlar" ) was an area in the highlands of central Anatolia (Ankara, Çorum, Yozgat Province) in modern Turkey. Galatia was named for the immigrant Gauls from Thrace (cf. Tylis), who settled here and became its ruling caste in the 3rd century BC, following the Gallic invasion of the Balkans in 279 BC. It has been called the "Gallia" of the East, Roman writers calling its inhabitants "Galli" ("Gauls" or "Celts").
Armenian Highlands The Armenian Highlands (Armenian: Հայկական լեռնաշխարհ , "Haykakan leṙnašxarh " ; also known as the Armenian Upland, Armenian plateau, Armenian tableland, or simply Armenia) is the central-most and highest of three land-locked plateaus that together form the northern sector of the Middle East. To its west is the Anatolian plateau which rises slowly from the lowland coast of the Aegean Sea and converges with the Armenian Highlands to the east of Cappadocia. To its southeast is the Iranian plateau, where the elevation drops rapidly by about 2000 ft to 5000 ft above sea level. The Caucasus extends to the northeast of the Armenian Highlands. To the southwest of the Armenian Highlands is Upper Mesopotamia.
