The Galatians: Celts in Ancient Turkey
In 278 BC, Celtic warriors crossed into Asia Minor and established a kingdom in the heart of modern Turkey. The Galatians maintained their Celtic language and identity for centuries, far from the Atlantic homeland, and are remembered in one of the most famous letters in history.

The Farthest East
The Celtic world is usually imagined as an Atlantic phenomenon -- Ireland, Scotland, Wales, Brittany, the green and rain-swept fringes of western Europe. But at their greatest extent, Celtic-speaking peoples ranged far beyond the Atlantic. The most dramatic example is Galatia, a Celtic kingdom established in the highlands of central Anatolia, in what is now Turkey, around 270 BC. The Galatians maintained their Celtic language and tribal identity for over three centuries, making them one of the most geographically isolated Celtic communities in history.
The story of how Celtic warriors ended up in the heart of Asia Minor is one of the stranger chapters in ancient history, and it reveals just how mobile, aggressive, and adaptable the Celtic peoples of the La Tene period truly were.
The Great Raid
In 280 BC, a large force of Celtic warriors from the middle Danube region launched a major southward migration into the Balkans. This was part of a broader pattern of Celtic expansion that had been underway for over a century, driven by population pressure, political instability within the Celtic world, and the lure of wealthy Mediterranean civilizations to the south.
One group, led by a chieftain named Brennus -- possibly a title rather than a personal name, echoing the Brennus who had sacked Rome a century earlier -- pushed into Greece and attacked the sanctuary of Delphi in 279 BC. Ancient sources claim that the attack was repelled by divine intervention -- earthquakes, thunderstorms, and the appearance of gods on the battlefield -- but the more likely explanation is a combination of Greek military resistance and the logistical difficulties of sustaining a large raiding force in mountainous terrain.
After the failed assault on Delphi, the Celtic force fragmented. One group, comprising three tribes -- the Trocmi, Tolistobogii, and Tectosages -- crossed the Hellespont into Asia Minor in 278 BC, invited by Nicomedes I of Bithynia, who wanted Celtic mercenaries for his own wars against his brother. Having served their purpose, the Celts carved out their own territory in the rugged highlands of central Anatolia, an area that would bear their name for centuries: Galatia.
Life in Galatia
The three Galatian tribes divided their territory among themselves and established a political system that reflected Celtic social organization adapted to Hellenistic conditions. Each tribe was subdivided into four septs, each governed by a tetrarch, creating a system of twelve tetrarchies overseen by a common council that met at a place called Drunemeton -- a name meaning "sacred oak grove" in Celtic, revealing the persistence of druidic religious traditions far from their European heartland.
The Galatians quickly became a significant power in Anatolian politics. They fought as mercenaries for various Hellenistic kingdoms, raided settled communities across Asia Minor, and extracted tribute from Greek cities that could not resist their military pressure. The "Dying Gaul," one of the most famous sculptures of antiquity (known today through a Roman marble copy), depicts a Galatian warrior in his death throes and was originally commissioned by Attalus I of Pergamon to celebrate his victory over Galatian raiders around 240 BC.
Despite living in a Hellenistic cultural environment, the Galatians maintained their Celtic identity with remarkable persistence. Saint Jerome, writing in the late fourth century AD, noted that the Galatians still spoke a language similar to that of the Treveri, a Celtic tribe from the Moselle region of what is now Germany. If this observation is accurate, it means the Galatian Celtic language survived for over six hundred years in the heart of Anatolia, a testament to the strength of Celtic cultural identity.
Rome and the Galatians
The Galatians came under Roman influence in the second century BC and were gradually integrated into the Roman system. They fought alongside Rome against Mithridates VI of Pontus, one of Rome's most dangerous enemies, and their loyalty was rewarded with recognition and eventual incorporation as a Roman client kingdom.
In 25 BC, when the last Galatian king, Amyntas, died, Augustus annexed Galatia as a Roman province. The region became thoroughly Romanized and later Christianized, but its Celtic name endured. When the Apostle Paul wrote his Epistle to the Galatians -- one of the foundational texts of Christian theology -- he was writing to communities in this same region, communities that had been established among the descendants of Celtic warriors who had marched east from the Danube three centuries earlier.
The Galatians are mentioned throughout the New Testament and in numerous classical sources, making them paradoxically one of the best-documented Celtic peoples despite being the most geographically remote from the Celtic homeland.
What the Galatians Tell Us
The Galatian story challenges the island-centric view of Celtic civilization. The Celtic languages family tree included branches that extended far beyond the Atlantic seaboard, and the Celts were not merely passive inhabitants of western Europe but active participants in the great power politics of the Hellenistic world.
For those tracing Celtic heritage, the Galatians are a reminder that the Celtic world was vast, diverse, and interconnected. The same cultural traditions -- the druidic oak groves, the warrior aristocracy, the distinctive La Tene art -- that defined Celtic identity in Gaul and Britain were carried to the highlands of Turkey by migrants who never forgot where they came from. Their language survived for centuries in isolation, a spoken monument to the resilience of Celtic identity in the most unlikely of settings.
