This map depicts Europe during the period of Celtic dominance. Between the sixth and third centuries B.C., the Celts, a group of barbarian tribes from central Europe, conquered a vast region extending from Iberia to the Black Sea. They were driven back and defeated by the Romans in the third and second centuries B.C.
