The Gothic War refers to a series of conflicts that occurred between the Eastern Roman Empire and the Goths, a group of Germanic tribes, during the 3rd century AD. The war was primarily fought over territory and control, as the Goths sought to expand their influence in the region. The conflict included significant battles and the eventual defeat of the Goths, which helped to stabilize the Eastern Roman Empire for a time. The war is notable for the involvement of key figures such as the Roman Emperor Valens, who led the Eastern Roman forces. The Gothic War also set the stage for future conflicts between the Romans and various barbarian groups, ultimately contributing to the decline of the Western Roman Empire.
