First Kappel War

Switzerland [1529]

Quick Summary

The First Kappel War, in 1529, was one of two conflicts during the Swiss Reformation. It arose when five Roman Catholic Swiss cantons formed the Christian Union and allied with Austria to counter Zurich's spread of Protestantism. Zurich responded by marching against the Union, but the conflict was brief. An armistice was signed at Kappel, leading to an agreement where the Catholic districts renounced their Austrian alliance and granted religious freedom in shared territories. This war was a precursor to the Second Kappel War in 1531, which resulted in a Catholic victory and the death of Protestant leader Huldrych Zwingli.12
