Jan Hus (hʊs; ˈjan ˈɦus; 1370 – 6 July 1415), sometimes anglicized as John Hus or John Huss, and referred to in historical texts as Iohannes Hus or Johannes Huss, was a Czech theologian and philosopher who became a Church reformer and the inspiration of Hussitism, a key predecessor to Protestantism, and a seminal figure in the Bohemian Reformation. Hus is considered by some to be the first Church reformer, even though some designate the theorist John Wycliffe. His teachings had a strong influence, most immediately in the approval of a reformed Bohemian religious denomination and, over a century later, on Martin Luther. Hus was a master, dean and rector at the Charles University in Prague between 1409 and 1410. Jan Hus was born in Husinec, Bohemia, to poor parents. In order to escape poverty, he trained for the priesthood. At an early age, he traveled to Prague, where he supported himself by singing and serving in churches. His conduct was positive, and reportedly, his commitment to his studies was remarkable. After earning a Bachelor of Arts degree and being ordained as a Catholic priest, Hus began to preach in Prague. He opposed many aspects of the Catholic Church in Bohemia, such as its views on ecclesiology, simony, the Eucharist, and other theological topics. When Alexander V was elected pope, he was persuaded to side with Bohemian Church authorities against Hus and his disciples. He issued a Papal bull that excommunicated Hus; however, it was not enforced, and Hus continued to preach. Hus then spoke out against Alexander V's successor, Antipope John XXIII, for his selling of indulgences. Hus's excommunication was then enforced, and he spent the next two years living in exile. When the Council of Constance assembled, Hus was asked to be there and present his views on the dissension within the Church. When he arrived, with a promise of safe-conduct, he was arrested and put in prison. He was eventually taken in front of the council and asked to recant his views.
