Duchy of Franconia
At this time the duchy, which was divided into numerous "Gaue" (counties), took the shape which it retained throughout the Middle Ages. It stretched south of Frankish Austrasia (the later Duchy of Franconia) along the Upper Rhine, Lake Constance, up the High Rhine, and down the Danube to the Lech tributary. The Lech, separating Alamannia from the Duchy of Bavaria in the east, did not form, either ethnologically or geographically, a very strong boundary, and there was a good deal of intercommunion between the two peoples.
