In May 1412, however, the difficulties caused by the Papal schism brought the reform movement in Bohemia to a crisis. King Ladislas of Naples, who still recognised Gregory the Twelfth as Pope, had thus incurred the enmity of John XXIII., who had succeeded Alexander V. as Roman Pope. John, therefore, resolved to go to war with the King of Naples, and--a proceeding which it must be added was not exceptional in those days--to obtain the necessary funds by the granting of indulgences. It was declared that all those who either took part in the campaign against Naples, or assisted the enterprise by grants of money, should receive the same remission of sins which had formerly been promised to the Crusaders who had liberated the sepulchre of Christ. The Bohemians, who were not long after to suffer from a 'crusade' similar to that now proclaimed against Naples, received the news of the Papal decision with great displeasure. When Wenceslas Tiem, Dean of Passau, arrived at Prague, with the purpose of collecting, by the sale of indulgences, funds for the Papal See, public excitement was naturally yet greater. Boxes to receive the donations of the faithful were placed before the Cathedral Church of St. Vitus, the Tyn Church, and on the Vysehrad. These proceedings caused particular indignation at the University, where the party favourable to Church reform now had entirely the upper hand. Hus summoned the members of the University to a _disputatio_, according to the mediæval custom. It took place in the large hall of the Carolinum, and the subject of the _disputatio_ was formulated in the question 'whether according to the law of Jesus Christ it was permissible and befitting for the honour of God, the salvation of the Christian people and the welfare of the kingdom, that the faithful of Christ should approve of the Papal bulls which proclaimed a crusade against Ladislas, King of Apulia, and his accomplices?' Both Hus and Jerome of Prague violently attacked the use of indulgences for the purpose of supplying the Roman See with funds for temporal purposes. The theological faculty soon after again condemned the forty-five 'articles' from Wycliffe's writings, and added six more that were attributed to Hus and said to contain the views on indulgences which he had expressed at the recent _disputatio_. Pope John also took action against Hus, and decreed the 'aggravation' of the sentence of excommunication that had already been pronounced against him. The movement had thus taken a distinctly revolutionary character, and Hus fled from Prague in November 1412, after having published an 'Appeal from the Sentence of the Roman Pontiff to the Supreme Judge, Jesus Christ.' He first retired to Kozi Hradek, a castle belonging to one of his adherents, John of Usti.
