Clovis Ier

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.

In 500 (dated by Marius of Avenches), near the castrum of Dijon and the river Ouche, Clovis I intervened in the Burgundian civil war alongside Godegisel, brother of King Gundobad. Dissatisfied with his share (Geneva versus Lyon/Vienne), Godegisel had secretly promised Clovis an annual tribute and territorial cessions. When Gundobad, deceived, marched with his brother against the Franks, Godegisel turned and joined Clovis: their combined army crushed Gundobad’s, who fled to Avignon through the Rhône marshes. Godegisel proclaimed himself king and went to Vienne. Clovis then besieged Avignon, lacked siege engines, negotiated a heavy tribute and raised the siege (Visigothic mediation by Alaric II). In 501 Gundobad, allied with the Visigoths, retook Vienne, executed Godegisel and restored his power — Burgundy remained independent, but under Frankish pressure.

In spring 507, on the plain of Vouillé near Poitiers, the Frankish army of Clovis I and his son Theuderic faced the Visigoths of Alaric II, reinforced by Auvergnat militia under Apollinaris of Clermont. The Franks crossed the Loire toward Poitiers; Alaric marched north to stop them, without hoped-for Ostrogothic support and while part of his forces was engaged in Hispania against the Eastern Romans. According to tradition Alaric was killed in battle (Gregory; the detail of Clovis’s own hand is sometimes debated), triggering Visigothic flight, while the Auvergnats resisted to the last man. Victory opened Aquitaine to the Franks: capture of Toulouse (508), Bordeaux, vassalage of Auvergne; the Visigoths kept little beyond Septimania and part of Provence. From 508 Clovis made Paris his capital. Anastasius granted him the honorary title of consul.
