In 1414, a Czech theologian named Jan Hus was called before the Council of Constance for heresy against the Catholic Church and Pope. Jan Hus had preached about the need to reform the corruption within the Church, desiring to adhere more to a more communal Christianity that he believed the New Testament spoke of, and for that he had been excommunicated numerous times. His life up to this point set the groundwork for the eventual history of the Catholic Church and the Holy Roman Empire to change forever.

Another major aspect of Charles IV’s authority was the elevation of Prague as a major player on the world stage for centuries to come.
