A few days later he decreed a general arming of the people, reminding the Bohemians of an ancient decree, according to which those who did not give their aid when Bohemia was in danger should lose their lives and their estates. He therefore summoned all to join him in arms at Litomerice, but a few Romanist lords alone obeyed the Royal command. The feeling was general that the Diet's sanction was necessary for such a general armament. The Praguers took the lead in the opposition to Ferdinand, and the movement in their city had a strongly democratic character.[31] Mistrusting the energy of their magistrates, the citizens, both of the old and of the new town, at a general meeting on January 23, 1547, resolved that in future all matters of great importance should be decided at general meetings of the citizens, who were to be called together by the town bells. They further declared that a general arming of the people, without the consent of the Diet, was contrary to the law of the land. Many Bohemian towns, such as Kolin, Kourim, Caslav, Cesky Brod, made common cause with Prague, which they recognised as the 'head of the Estate of the citizens.' Many knights and nobles, particularly those who belonged to the 'unity' of the Bohemian brethren, were in sympathy with the towns, and, indeed, agreed to their suggestion that a meeting of the Estates should take place. This was distinctly unconstitutional, as the King alone had the right of summoning the Estates. On February 13 a private meeting of the nobles took place at the house of Lord Bohus Kostka, in the Celetná Ulice. All present agreed to act in accord with the citizens, and after a prolonged conference 'proceeded to the Staromestské Námesti singing "True Christians, let us strongly hope"; they then lifted their hats, berets and caps when passing the Tyn Church, and retired to their abodes.' A more formal meeting of the Estates took place in the following month. King Ferdinand had, indeed, written from Dresden to the high officials of Prague, ordering them to do everything in their power to prevent this meeting of the Estates, who had not been summoned by their King. They, none the less, met on March 18 at the Carolinum, where 800 nobles, knights and representatives of the Bohemian towns (except Plzen and Budejovice) were present. They formed a confederacy and formulated their demands in forty-five articles, which mainly tended to curtailing the Royal prerogative, securing religious freedom, and affirming the elective character of the Bohemian throne. It was resolved to bring these demands before King Ferdinand by a deputation chosen from among the members of the Diet, and the Estates also entered into negotiations with the Protestant princes of Germany, and resolved to equip an army.
