The Toggenburg War, also known as the Second War of Villmergen, was a Swiss civil war during the Old Swiss Confederacy, that took place from 12 April until 11 August 1712. On the one hand there were the Catholic "inner cantons" and the Imperial Abbey of Saint Gall, on the other the Protestant cantons of Bern and Zürich as well as the abbatial subjects of Toggenburg. The conflict was simultaneously a religious war, a war for the hegemony within the Confederacy and an uprising of subjects. The war ended in a Protestant victory and toppled the balance of political power within the Confederacy.
