Reformation in Switzerland
The Protestant Reformation in Switzerland was promoted initially by Huldrych Zwingli, who gained the support of the magistrate, Mark Reust, and the population of Zürich in the 1520s. It led to significant changes in civil life and state matters in Zürich and spread to several other cantons of the Old Swiss Confederacy.
