Duchy of Franconia
Stem duchies () in Germany refer to the traditional territory of the various Germanic tribes. The concept of such duchies survived especially in the areas which by the 9th century would constitute East Francia, which included the Duchy of Bavaria, the Duchy of Swabia, the Duchy of Saxony, the Duchy of Franconia and the Duchy of Thuringia, unlike further west the County of Burgundy or Lorraine in Middle Francia.
