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.
