Hussitism began during the long reign of Wenceslas IV (1378–1419), a period of papal schism and concomitant anarchy in the Holy Roman Empire. It was precipitated by a controversy at Charles University in Prague. In 1403 Jan Hus became rector of the university. A reformist preacher, Hus espoused the anti-papal and anti-hierarchical teachings of John Wycliffe of England, often referred to as the "Morning Star of the Reformation". Hus' teaching was distinguished by its rejection of what he saw as the wealth, corruption, and hierarchical tendencies of the Roman Catholic Church. He advocated the Wycliffe doctrine of clerical purity and poverty, and insisted on the laity receiving communion under both kinds, bread and wine. (The Roman Catholic Church in practice reserved the cup, or wine, for the clergy.) The more moderate followers of Hus, the Utraquists, took their name from the Latin "", meaning "under each kind". The Taborites, a more radical sect, soon formed, taking their name from the city of Tábor, their stronghold in southern Bohemia. They rejected church doctrine and upheld the Bible as the sole authority in all matters of belief.
