Tradition gives an early date to the first signs of sympathy between Z̆iz̆ka and Hus. Within a walk of the village of Husinec stands the old town of Prachatice, where the ruins are still shown of the school in which Z̆iz̆ka and Hus are said to have studied together. However this may be, there can be no doubt that it was very soon after the death of Hus that Z̆iz̆ka began to assume that position of leadership among the extremer Utraquists, which ultimately gained him such fame both among friends and enemies. This section of Reformers had already discovered that they did not receive that sympathy from the citizens of Prague which they believed to be their due. Many of them were compelled to leave the city; and they gathered together on a mountain near Austi, to which they gave the name of Tabor, and to which their supporters gradually flocked from all parts of the kingdom. These gatherings so alarmed Wenceslaus that they even weakened his hostility to the Council of Constance; and not only the followers of Nicholaus and Z̆iz̆ka, but even some of the more moderate Utraquists became objects of his suspicion. This change of feeling naturally increased the hopes of Sigismund, and he became even more sanguine of success, and more bitter against the followers of Hus, when the Council of Constance elected, under the name of Pope Martin V., that Cardinal Colonna, who had urged upon John XXIII. the first proposal for the condemnation of Hus. Under the influence of this new Pope, all the schemes of reform, which the Council had once thought of considering, were sacrificed to the one aim of the suppression of heresy; and in April, 1418, the Pope secured himself a freer hand by dissolving the Council of Constance. Urged, then, by pressure from Emperor and Pope, and by his own fear of Utraquistic excesses, Wenceslaus banished one of the Reformers from Prague, and recalled the Catholic clergy, who had been expelled from the city. He discovered, indeed, that Utraquism had taken so deep a root in Prague that it would be necessary to grant at least three churches to its preachers. But this concession did not satisfy the more zealous champions of the cause; and the favour shown by the King to the Catholics provoked riots among the Reformers. Then Wenceslaus demanded that the citizens should all give up their arms to him.
