First Defenestration of Prague

The Hussite Reformation: Revolution and Wars

With Jan Hus’s execution at the Council of Constance in 1415, the Church and Holy Roman Emperor believed that the issues of Bohemian heresy had been successfully resolved. However, Bohemia erupted into protest and revolt in response to the death of Jan Hus. Expelling the Catholic priests and throwing the city council members from the New Town Hall windows, the Hussites of Bohemia refused to accept the authority of the Church or their king. To quell this revolution, Holy Emperor Sigismund and Pope Martin V launched an invasion and five crusades against Hussite Bohemia, calling upon the Christian world to lend them aid. However, led by a man named Jan Žižka and later Prokop the Great, the Hussites would not be so easily defeated.
