In 1419 the King issued a decree ordaining that all priests who had been deprived of their livings because of their disapproval of communion in the two kinds, should be reinstated. Only in three churches were the Utraquists, as the adherents of the new doctrine were called, to continue to hold their religious services. The Utraquists, to show their strength, instituted processions through the streets of Prague, during which the sacrament was carried before the faithful. One of the most zealous Utraquists was the priest, John of Zelivo, a former Præmonstrate monk. On July 30, 1419, he headed a procession which, after violently interrupting a religious service which was being held in the Church of St. Stephen, according to the Roman rites, marched to the town hall of the Nové Mesto, situated in the Karlovo Námesti. The release of some adherents of the new faith who had been imprisoned there was demanded, but refused by the burgomaster, who was a Romanist. The Utraquists then, 'as an affront, called him a German and a hater of the chalice.'[11] Meanwhile the town councillors had barricaded their hall and threw stones on the crowd below, one of which struck the monstrance that Zelivo was carrying. The crowd--led, it is said, by Zizka, afterwards famous as a Hussite leader--stormed the town hall and threw the town councillors into the market-place below, where they were killed by the people. This 'defenestration,' as it was called in Bohemia, marks the beginning of the great religious struggle in Bohemia, as the defenestration from the Hradcany windows in 1618 marks its end; for only two years after the last-named event the battle of the White Mountain established religious uniformity in Bohemia.
