Battle of the Catalaunian Plains
Flavius Aetius (Aëtius; ; c. 391 – 454) was a Roman general of the closing period of the Western Roman Empire. He was a military commander and the most influential man in the Western Roman Empire for two decades (433454). He managed policy in regard to the attacks of barbarian federates settled throughout the Western Roman Empire. Notably, he mustered a large Roman and allied ("foederati") army in the Battle of the Catalaunian Plains, ending the Huns' devastating invasion, led by Attila in 451, though another devastating invasion of the Huns occurred in the year after that.
