Whom did the ancient Romans and Greeks consider barbarians?

The Romans and Greeks called barbarians those who: wore a beard, wore pants, spoke a different language, their culture and way of life differed from that of antiquity. We can say that all northern peoples who lived in Europe at that time fell under such criteria. These include the Sarmatians, Germans, Celts, Thracians, etc. True, the expression “barbarian” did not always mean underdeveloped or wild. They just called strangers and strangers.
