He conquered Gaul (apart from its southeast) taking its central area from a Roman rump state (the Domain of Soissons), the southwest from the Visigoths and the east form the Burgundians. He conquered the lands in Alemanni in southern Germany, Switzerland and north-eastern France (Alsace and Lorraine).
