Duke Albert, thirsting for revenge, sought to destroy the League, but while striving to accomplish that purpose he was murdered by his nephew, Duke John of Swabia. The German imperial power was supplanted by that of the Austrian dukes. Henry, the next emperor, was chosen from the Luxembourg and Bavarian family. He recognized the League and confirmed the people in all their rights and privileges, which subjected him to the ill-will of Albert’s sons and grandsons. After Henry’s death Louis of Bavaria was elected Emperor over Frederick of Austria. The Forest Cantons paid allegiance to him because they knew they had nothing good to expect from Austria. Thereupon Leopold, Frederick’s brother, decided to retaliate, and nearly all the nobles of Swabia and German Switzerland joined him.
