Question: Who started the Swiss Reformed Church and initially promoted the Reformation in Switzerland?
Related documents: [0]  [DOC] The Protestant Reformation in Switzerland was promoted initially by Huldrych Zwingli, who gained the support of the magistrate (Mark Reust) and 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. Seven cantons remained Roman Catholic, though, which led to inter-cantonal wars known as the Wars of Kappel. After the victory of the Catholic cantons in 1531, they proceeded to institute counter-reformatory policies in some regions. The schism and distrust between Catholic and Protestant cantons would define their interior politics and paralyse any common foreign policy until well into the 18th century. [END]
