Overview

The Kingdom of Soissons (a modern scholarly term; the "Domain of Soissons") was the last Roman rump state in northern Gaul, surviving the collapse of central Western imperial authority. It emerged when Aegidius, the Roman magister militum per Gallias, refused to recognise the regime that murdered Emperor Majorian (461) and held northern Gaul independently, based at Soissons. Its territory stretched roughly between the Somme and the Loire rivers, and its population was Gallo-Roman.

History

Aegidius (d. 464 or 465 — sources differ) was succeeded by his son Syagrius, who ruled the domain from his father's death until 486. Gregory of Tours calls Syagrius rex Romanorum ("king of the Romans"), though whether he or contemporaries actually used a royal title is uncertain; the Chronicle of Fredegar styles him a Roman patrician. It is disputed among scholars whether the "kingdom" was a coherent state or a looser holding, and how far it saw itself as still Roman.

Decline and legacy

The domain fell to the Franks: Clovis I (with his kinsmen Ragnachar and Chararic) defeated Syagrius at the Battle of Soissons in 486. Syagrius fled south to the Visigothic king Alaric II at Toulouse, but under Frankish threat Alaric handed him over; Syagrius was imprisoned and secretly killed (486/487). The battle is conventionally taken to mark the end of Roman rule in Gaul and a decisive step in Clovis's creation of Francia.
