The Battle of Adrianople pitted the Eastern Roman Empire against Gothic forces and ended in a catastrophic Roman defeat. Emperor Valens was killed, and the Roman field army was shattered in one of the empire's worst military disasters.
Adrianople exposed the vulnerability of Rome's late imperial military structure and signaled the growing importance of migrating and federated peoples inside imperial politics. Historians often treat it as a major milestone in the transformation of the Roman world.
