Old Zürich War



The Old Zurich War (Alter Zürichkrieg), 1440–46, was a conflict between the canton of Zurich and the other seven cantons of the Old Swiss Confederacy over the succession to the Count of Toggenburg.
In 1436, Count Friedrich VII of Toggenburg died, leaving neither heir nor will. The canton of Zurich, led by burgomaster Rudolf Stüssi, claimed the Toggenburg lands; the cantons of Schwyz and Glarus made counter-claims, backed by the other cantons. In 1438 Zurich occupied the disputed area and cut off grain supplies to Schwyz and Glarus. In 1440, the other cantons expelled Zurich from the confederation and declared war. Zurich retaliated by making an alliance with Frederick III, Holy Roman Emperor of the house of Habsburg.
