Cause → Event → Consequence
Gothic tribes, primarily Thervings and Greutungs, along with non-Gothic Alans, had crossed into Roman territory and rebelled as part of the broader Gothic War of 376–382. Tensions between the Gothic refugees and Roman authorities escalated into open conflict, prompting Emperor Valens to lead his Eastern Roman army against the Gothic forces under Fritigern.
On 9 August 378, the Eastern Roman army under Emperor Valens engaged Gothic rebels near Adrianople in the Roman province of Thracia. The battle ended in an overwhelming Gothic victory. Emperor Valens himself was killed during the fighting, making it one of the most catastrophic Roman military defeats in centuries.
The Gothic triumph left the Eastern Roman frontier severely weakened and demonstrated that barbarian forces could decisively defeat a Roman imperial army in open battle. Historians have long regarded the battle as a key event in the chain leading to the collapse of the Western Roman Empire in the 5th century. Ammianus Marcellinus documented it as the climax of his historical account.
