The Franks were originally German people living along the Rhine River bordering the Alemanni, Chatti, Marcomanni, and Quadi; the latter three were subject to military expeditions by the Frankish tribes, which resulted in their conquests. The Franks established a power base across the Rhine and expanded to the Elbe and to the Loire, fighting the Lombardii, Burgundii, Alemanni, Saxons, and Western Roman Empire, conquering most of Gaul and Western Europe. They were once humbled by the Saxons by a military expedition, forced to stop their attacks on their empire in return for survival. The Franks continued their wars against Rome and took over Arles, Bordeaux, and Samarobriva, taking over all of West Europe for themselves. After the fall of Rome, they conquered the Alemanni and founded the Merovingian Empire.
