Kingdom of the Lombards
During the Migration Period, the High German-speaking tribes settled in what became Alamannia, the Duchy of Bavaria and the Kingdom of the Lombards. At the same time the Franconian-speaking tribes settled the area between those two rivers before crossing the Rhine to conquer Northern Gaul, where, under the Merovingians, they created the Frankish kingdom, Francia, which eventually stretched down to the Loire.
