Well, ignorant lefty child who received a government school "education;"  Attilla was the son of a Hunnic King who swore loyalty to the Empire.   As was their custom, the Romans took his son as a hostage to Rome where he was educated and  introduced to Roman society and private and public life.   He was essentially Roman royalty.

Ultimately, he rejected his father's conciliation with the Romans and went to war with the by then drastically weakened Empire, which did arrogance and condescention even better than today's Democrats condescend to "deplorables, and made a pretty good dent in them.   Another "barbarian," Aetius I think was his name led the Romans and their allies against Attilla somewhere in Gaul, a place we've never identified, and in desperate battle defeated him.   People on your side of the ditch if they knew anything would call him a freedom fighter, a 4th Century Che, but then your teachers told you that lefty and smart were synonyms.
