The Battle of Vouillé or Campus Vogladensis was fought in the northern marches of Visigothic territory, at a small place near Poitiers, (Gaul) in the spring 507. between the Franks commanded by Clovis and the Visigoths of Alaric II, the conqueror of Spain.

Clovis and Anastasius I of the Byzantine Empire agreed that each will attack the Goths on their side.

The Franks crossed the Loire river. Clovis himself killed Alaric. The battle forced the Goths to retreat to Septimania, which they continued to hold. The success at Vouillé allowed the Franks to control the southwestern part of France, and capture Toulouse. Alaric's illegitimate son Gesalec tried to organize a counterstrike at Narbonne, but he was deposed and ultimately killed when Narbonne was taken by Burgundian allies of the Franks, who held it until 511. The Franks might have pushed farther, had Theodoric the Great not intervened.

Frankish Aquitaine, formerly linked to Hispano-Roman trade routes and territories, drifted into a role as an isolated outpost, to judge from the lack of trade items in its 7th and 8th century archaeology. Its Frankish kings resided at Toulouse.
