What are some specific achievements of the people that Romans called "Barbarians"

Good grief! That term refers to lots of different people -- basically, anyone who wasn't a Roman citizen.

Indeed there were many barbarians! but this doesnt help me answer the question of what their achievements were?

Nope.

What you need to do is identify some of them. Then you will be able to look them up and see what each group is known for. Can you tell us the names of some of these barbarians?

I know Attila!

Definitely!

mmmmmk thanks, i think i can do it from here...

MChicken: The Roman vision of who were Barbarbians changed with time, remember, Romans Ruled many years. What Caesar saw as barbaric in Gaul, Constantine saw in the Arians.
