ORIGIN OF "CELT" TERM The name ‘Celt’ comes from the Greek Keltoi, which, like the Roman name for them, also means ‘barbarians’. Exactly when the Ancient Greeks came into contact with the proto-Celts is open to speculation, but it is known that the Celtic people interacted with various Greek civilizations over a lengthy period. Sometimes Celts might be found serving as mercenaries in Greek wars and sometimes they fought against various Greek forces.
It is probable that interactions of some kind took place from at least as early as the end of the Greek Dark Age. This lasted from around 1200 to 800 BCE and followed the collapse of earlier Greek civilizations. The Greek Dark Age also coincided with the collapse of other societies in the Eastern Mediterranean region, resulting in a dearth of written records from that period.
