Barbarians in the Byzantine Empire

In the Byzantine Empire, the term "barbarians" was used for several non-Greek people. The Byzantines regarded most neighbouring people as barbarians. The Bureau of Barbarians was a department of government dealing with matters relating to these "barbarians". In the Early Middle Ages in Europe, the term was applied to Huns, Goths, Pechenegs, Avars, Slavs, Bulgars, and others.
