<P> Galatia was bounded on the north by Bithynia and Paphlagonia, on the east by Pontus and Cappadocia, on the south by Cilicia and Lycaonia, and on the west by Phrygia . Its capital was Ancyra (i.e. Ankara, today the capital of modern Turkey). </P> <P> The terms "Galatians" came to be used by the Greeks for the three Celtic peoples of Anatolia: the Tectosages, the Trocmii, and the Tolistobogii . By the 1st century BC the Celts had become so Hellenized that some Greek writers called them Hellenogalatai (Ἑλληνογαλάται). The Romans called them Gallograeci . Though the Celts had, to a large extent, integrated into Hellenistic Asia Minor, they preserved their linguistic and ethnic identity . </P> <P> By the 4th century BC the Celts had penetrated into the Balkans, coming into contact with the Thracians, Macedonians and Greeks . In 380 BC they fought in the southern regions of Dalmatia (present day Croatia), and rumors circulated around the ancient world that Alexander the Great's father, Philip II of Macedonia had been assassinated by a dagger of Celtic origins . Arrian writes that "Celts established on the Ionic coast" were among those who came to meet Alexander the Great during a campaign against the Getae in 335 BC . Several ancient accounts mention that the Celts formed an alliance with Dionysius I of Syracuse who sent them to fight alongside the Macedonians against the Thebans . In 279 BC two Celtic factions united under the leadership of Brennus and began to push southwards from southern Bulgaria towards the Greek states . According to Livy, a sizable force split off from this main group and head toward Asia Minor . </P> <P> For several years a federation of Hellespontine cities, including Byzantion and Kalchedon prevented the Celts from entering Asia Minor but this changed when Nikomedes I of Bithynia allied with some of the Celtic leaders in a war against his brother Zipoetes and the Seleucid king Antiochus I. When the Celts finally entered Asia Minor chaos ensued until the Celts were briefly routed by Antiochus' army in the Battle of Elephants . In the aftermath of the battle the Celts withdrew to Phrygia, eventually settling in Galatia . The territory of Celtic Galatia included the cities of Ancyra (present day Ankara), Pessinus, Tavium, and Gordion . </P>
