At the end of the 14th century, a moral reform movement began in Prague. Reformers preached in Czech throughout German-dominated Bohemia, calling for a return to God and frequent communion. When John Hus, who questioned papal authority, became their leader, he was excommunicated. He appealed, and was marched out and burned at the stake. The Hussites were eventually forced back into orthodoxy; however, their reforms survived only in the Moravian Brethren, who later influenced John Wesley.
