The Franks, Germanic peoples that invaded the Western Roman Empire in the 5th century, were first led by individuals called dukes and reguli. The earliest group of Franks that rose to prominence was the Salian Merovingians, who conquered most of Roman Gaul, as well as the Gaulish territory of the Visigothic Kingdom, following the Battle of Vouillé in 507 AD.
The sons of Clovis I, the first King of the Franks, conquered the Burgundian and the Alamanni Kingdoms. They acquired Provence, and went on to make the peoples of the Bavarii and Thuringii their clients. The Merovingians were later replaced by the new Carolingian dynasty in the 8th century. By the late 10th century, the Carolingians themselves had been replaced throughout much of their realm by other dynasties.
