Celts, term used by ancient and modern writers to describe a population group occupying in prehistoric and historic times lands mainly north of the Mediterranean, from the Spanish peninsula and the British Isles in the west to Galatia in central Asia Minor (see GALATIANS). Their unity can be recognized from the fact that they had a common speech, evinced in place-names, and from a common artistic style. It is generally thought that the Celts spread from the region of the Upper Danube during the Bronze Age. Celtic tribes invading from across the Rhine and settling in Gaul came to be known themselves as Gauls. Hence the invaders of Italy who sacked Rome in c.370 BC and who entered the Balkans and raided Delphi in 279 BC and crossed the Hellespont in 278 are referred to either as Celts or as Gauls. The latter gave their name to the territory of Galatia, where Celtic was still spoken in the fifth century AD. The Celts in Europe were overrun by invading Germans crossing the Rhine from the third century BC onwards and by the migrations of the Cimbri and Teutones soon after 120 BC, and so they withdrew from Bohemia and south Germany. They were also conquered by Rome in the Gallic wars and some, e.g. the Belgae, became assimilated to their invaders.
