A Roman general of the late period of the Western Empire born in Dorostolus, Moesia, who led the Gallic forces to defeat Attila and the Huns. Son of Gaudencio who, despite descending from a family of barbarians, was master of cavalry in the Western Empire. He followed a military career and spent some years as a hostage, first with Alaric and the Goths, and then in the camp of Roas, king of the Huns, and uncle of Attila. He led in Italy (424) to defeat the army of barbarians, mainly Huns, and obtained from the emperor the supreme command of the Gallic army in Placidia. Through trickery and slander he eliminated his rival, Count Boniface, who had been favored by the empress regent. Ambitious descended from Gaul against Boniface, who was mortally wounded in the ensuing battle.
Thus he gained a great military reputation and became the dominant personality of the Western empire (433-450), amassing for nearly twenty years political prestige and fortune. His greatest military victory was at Chalons-sur-Marne (451) in which he led the Gallic forces against Attila and his Huns, this would be the last significant triumph of the Western empire. Attila had claimed the hand of Honoria, sister of Emperor Valencinian III, as his wife (450) and demanded half of the western region as a dowry.
To speed up the decision, he invaded Gaul (451), but this untimely decision began his first military defeat. The imperial forces commanded by the Roman general with the help of the Visigoths, Alans and other peoples, detained the Huns in Orleans, forcing him to withdraw after the decisive defeat in the Battle of Châlonssu-Marme in the Catalonia Fields (451). Three years later (454) he appeared in court claiming the emperor's daughter in marriage for his son Gaudencio II. Valentinian III, suspecting his ambitions for the crown, killed him personally.
