Since finding out from the EBteam about the advances of the Barbarian factions and their technological achievement I have this question:
What made the "civilised" states like Hellenic states, the Roman states, Eastern states more civilised than the celts, germans or Sarmatians? Or on what real basis the barbarians where frowned upon by the civilised states?

PS:The Romans where barbarians too since they didnt speak Greek...

Hellenes
