The battle of the Catalaunian Plains (also known as Battle of the Campus Mauriacus, Battle of Maurica, Battle of the Catalaunian Fields or Battle of Chalons) that was fought in 451 between the alliance led by the Western Roman General Flavius Aetius, king of the Visigoths Theodoric I and the king of Alans Sangiban against the Hun Alliance commanded by Attila, the king of Ostrogoths Valamir and the king of Gepids Ardaric. With the addition of dozens of other tribes, the battle of the Catalaunian Plains can be rightly considered the first pan-European clash. It is equally complicated and controversial, as our info on the battle between the Last Roman Aetius and the Scourge of God Attila, is both limited and conflicting. In any case, this battle was decisive for the history of the Roman Empire and Europe and influenced events of the next centuries.
