Herzogtum Franken
Babenberg was a noble dynasty of Austrian margraves and dukes. Originally from Bamberg in the Duchy of Franconia (present-day Bavaria), the Babenbergs ruled the Imperial Margraviate of Austria from its creation in 976 AD until its elevation to a duchy in 1156, and from then until the extinction of the line in 1246, whereafter they were succeeded by the House of Habsburg.
