The Council of Constance, called by Emperor Sigismund, a supporter of Antipope John XXIII, burns Jerome of Prague following a trial for heresy.

Jerome of Prague (Czech: Jeronm Prask; Latin: Hieronymus Pragensis; 1379 30 May 1416) was a Czech scholastic philosopher, theologian, reformer, and professor. Jerome was one of the chief followers of Jan Hus and was burned for heresy at the Council of Constance.

The Council of Constance was a 15th-century ecumenical council recognized by the Catholic Church, held from 1414 to 1418 in the Bishopric of Constance in present-day Germany. The council ended the Western Schism by deposing or accepting the resignation of the remaining papal claimants and by electing Pope Martin V.

The council also condemned Jan Hus as a heretic and facilitated his execution by the civil authority, and ruled on issues of national sovereignty, the rights of pagans and just war, in response to a conflict between the Grand Duchy of Lithuania, Kingdom of Poland and the Order of the Teutonic Knights. The council is also important for its relationship to ecclesial conciliarism and Papal supremacy.
