Battle of Soissons
Soissons, Gaul (today France) · Extension of the Frankish kingdom – fall of the last Roman stronghold in Gaul
In 486, in the fifth year of Clovis I's reign, the Salian Franks — supported by Ragnachar, king of Cambrai — fought near Soissons against Syagrius, son of Aegidius, whom Gregory of Tours calls 'king of the Romans' (Romanorum rex). Syagrius then held the last enclave of Roman authority in northern Gaul, between the Loire and the Somme, often called the 'Kingdom of Soissons' (a contested historiographical label). Defeated, he fled to Toulouse to Visigothic king Alaric II, who handed him over in chains to Clovis's envoys; the victor had him secretly killed and seized his territory. The battle marks the end of the last remnant of Roman power in northern Gaul and nearly doubles Frankish territorial reach as far as the Loire.
