The Kingdom of Soissons originated in the reign of the Western Emperor Majorian. Majorian appointed Aegidius to be magister militum of the Gallic provinces. The remaining Roman territory in Gaul in the northwest was connected with the Roman possessions in the Auvergne, Provence, and Languedoc which connected these to Italy. During Majorian's reign, that corridor was annexed by the Germanic tribes now occupying Gaul, thus effectively cutting off Aegidius and his citizens from the Empire. Majorian and Aegidius had recovered the Roman position in most of Gaul, but with the death of Majorian in 461 the Roman position in the center and south deteriorated. These provinces were annexed by the Visigoths and Burgundians in the years 462-477, which left the remaining Roman territories in Gaul isolated. Aegidius maintained his own rule in the remnants of Roman Gaul that came to be known as the Domain or Kingdom of Soissons. In the chaos of contemporary Gaul, he maintained his power against Franks to his east and Visigoths to his south; his relations to the Romano-British of Brittany may have been friendly. Aegidius died in 464 or 465. His son Syagrius succeeded to the rule. In 486 Syagrius won the Battle of Soissons against the Frankish king Clovis I and the domain were thereafter under the control of the Roman.
