The Visigoths became tired of the romans’ demands, rebelled, and defeated the roman legions at Adrianople.
The Battle of Adrianople (9 August 378), sometimes known as the Battle of Hadrianopolis, was fought between an Eastern Roman army led by the Eastern Roman Emperor Valens and Gothic rebels (largely Servings as well as Greetings, non-Gothic Alans, and various local rebels) led by Fritigern. The battle took place in the vicinity of Adrianople, in the Roman province of Thracia (modern Edirne in European Turkey). It ended with an overwhelming victory for the Goths and the death of Emperor Valens.
As part of the Gothic War (376–382), the battle is often considered the start of the events which led to the fall of the Western Roman Empire in the 5th century.
