カタラウヌムの戦い
The Ostrogoths fought together with the Huns at the Battle of the Catalaunian Plains in 451. Following the death of Attila and the defeat of the Huns at the Battle of Nedao in 454, the Ostrogoths broke away from Hunnic rule under their king Valamir. Under his successor, Theodemir, they utterly defeated the Huns at the Bassianae in 468, and then defeated a coalition of Roman–supported Germanic tribes at the Battle of Bolia in 469, which gained them supremacy in Pannonia.
