Jan Hus, a theologian and rector at the Charles University, preached in Prague. In 1402, he began giving sermons in the Bethlehem Chapel. Inspired by John Wycliffe, these sermons focused on what were seen as radical reforms of a corrupt Church. Having become too dangerous for the political and religious establishment, Hus was summoned to the Council of Constance, put on trial for heresy, and burned at the stake in Constanz in 1415.
