In a thirty-year reign (481–511) Clovis defeated the Roman general Syagrius and conquered the Kingdom of Soissons, defeated the Alemanni (Battle of Tolbiac, 496) and established Frankish hegemony over them. Clovis defeated the Visigoths (Battle of Vouillé, 507) and conquered all of their territory north of the Pyrenees save Septimania, and conquered the Bretons (according to Gregory of Tours) and made them vassals of Francia. He conquered most or all of the neighbouring Frankish tribes along the Rhine and incorporated them into his kingdom.
