The term 'barbarian' is derived from the Greek word ‘barbaros’ which means a non-Greek. In Ancient Greece, the Greeks used the term towards those who didn't speak Greek and follow classical Greek customs. In the early modern period and sometimes later, the Byzantine Greeks used it for the Turks, in a clearly pejorative manner. In Ancient Rome, the Romans used the term towards non-Romans such as the Germanics, Celts, Gauls, Iberians, Thracians, Illyrians, Berbers, Parthians, and Sarmatians.
