Which civilization suffered invasions by nomads?

The Roman Empire suffered significant invasions by nomadic groups, particularly during its decline in the 4th and 5th centuries. Tribes such as the Huns, Vandals, and Goths invaded Roman territories, contributing to the empire's fragmentation. These invasions were part of a larger pattern of migration and conflict that reshaped Europe during the Late Antiquity period. Ultimately, these incursions played a critical role in the fall of the Western Roman Empire.
