The term "Barbari" refers to a group of ancient peoples who lived outside the boundaries of the Roman Empire. They were often seen as uncivilized by the Romans, who used the term to describe various tribes, including the Germans, Celts, and Huns. The Barbari played a significant role in the history of Europe, particularly during the decline of the Roman Empire. Barbari were known for their warrior culture and distinct social structures. They often engaged in raids and conflicts with the Romans, leading to significant changes in territorial control. Over time, some of these tribes settled in former Roman territories, contributing to the cultural and political landscape of medieval Europe.
