Aegidius (died 464 or 465) was the ruler of the short-lived Kingdom of Soissons from 461 to 464/465. Before his ascension he was an ardent supporter of the Western Roman emperor Majorian, who appointed him magister militum per Gallias ("Master of the Soldiers for Gaul") in 458. After the general Ricimer assassinated Majorian and replaced him with Emperor Libius Severus, Aegidius rebelled and began governing his Gallic territory as an independent kingdom. He may have pledged his allegiance to the Eastern Roman emperor Leo I. Aegidius repeatedly threatened to invade Italy and dethrone Libius Severus, but never actually launched such an invasion; historians have suggested he was unwilling to launch an invasion due to the pressure of the Visigoths, or else because it would leave Gaul exposed. Aegidius launched several campaigns against the Visigoths and the Burgundians, recapturing Lyon from the Burgundians in 458, and routing the Visigoths at the Battle of Orleans. He died suddenly after a major victory against the Visigoths; ancient historians say that he was assassinated, but do not give the name of the assassin, whereas modern historians believe it is possible that he died a natural death. After his death, he was succeeded by his son Syagrius, who was the last ruler of the Kingdom of Soissons. History
