The Visigoths now came into conflict with the Franks under their King Clovis I, who had conquered northern Gaul. Following a brief war with the Franks, Alaric was forced to put down a rebellion in Tarraconensis, probably caused by recent Visigoth immigration to Hispania due to pressure from the Franks. In 507, the Franks attacked again, this time allied with the Burgundians. Alaric II was killed at the Battle of Campus Vogladensis (Vouillé) near Poitiers, and Toulouse was sacked. By 508, the Visigoths had lost most of their Gallic holdings save Septimania in the south.
