Enrique el León
In 1142 the duchy passed to Henry the Lion, son of Henry the Proud. The struggle between Henry the Lion and Emperor Frederick I ended with Henry's loss of all his fiefs in 1180. The stem duchy was broken up into numerous fiefs. The Guelphic heirs of Henry the Lion retained only their allodial lands, the Duchy of Brunswick. The ducal title of Saxony went to Bernhard of Anhalt, a younger son of Albert the Bear of Brandenburg and founder of the Ascanian line of Saxon dukes. Besides Anhalt, Bernard received Lauenburg and the country around Wittenberg on the Elbe. These widely separate territories continued after 1260 under separate branches of the Ascanians as Saxe-Lauenburg and Saxe-Wittenberg.
