After Clovis's victories over the Alemanni east of the Rhine and over the Burgundians in the Rhone Valley, the Franks' growing power posed a threat to Alaric II's territory in Aquitaine and Hispania.
Despite Theodoric the Great's attempts to broker a peace between the factions, Clovis began a campaign to seize Aquitaine and Alaric's center of power in Toulouse.
[2] Clovis's army was slowed by a rain-swollen Vienne River, yet his forces were able to engage the Visigoths south of Vouillé.
[3] Despite being in a superior army in size and equipment, Alaric's soldiers wavered as all of the Auvergnat commanders except Apollinaris were killed.
[4] The battle forced the Visigoths to retreat to Septimania, which they continued to hold, and the Franks' success at Vouillé allowed them to control the southwestern part of France and to capture Toulouse.
