Though George had been chosen unanimously, difficulties arose almost immediately with regard to his coronation, a ceremony to which the Bohemians have always attached the utmost importance. Finally, through the intervention of King Matthias Corvinus of Hungary, two Hungarian bishops undertook to crown the King, and the ceremony was performed with much splendour in St. Vitus's Cathedral on May 7, 1458. The chroniclers state that when the crown was placed on the King's head one of the largest jewels fell to the ground. This was afterwards interpreted as signifying that Breslau, which as capital of Silesia was one of the greatest towns in the lands of the Bohemian crown, would never be in Podebrad's power. During his [Illustration: CHAPEL OF TOWN HALL] eventful reign (1458-1471) King George was engaged in constant warfare with the rebellious Catholic nobles and with King Matthias of Hungary. That prince had indeed been an ally of George at the beginning of his reign, but his views changed when it became certain that an agreement between the Papal See and Podebrad was impossible. The King of Hungary now declared war against Bohemia, and attempted to supplant George as ruler of that country. In 1452 the King assembled the Estates at Prague; the Bohemian envoys, who had just returned from Rome, the Papal legate and the Romanist bishops of Breslau and Olmütz were also present. The King presided, sitting under a baldachin with his consort, Queen Johanna, at his right and his sons at his left. Podebrad spoke strongly of the treachery of the Roman Court, and ended by declaring 'that the Pope should know that he would not sell his faith for a kingdom, that he, his wife and his children were ready to risk their kingdom and their lives for the blessed blood' (_i.e._, communion in the two kinds). This speech greatly affected all present, few of whom could refrain from tears. The campaigns that occupied the last years of Podebrad hardly belong to a history of Prague. On February 22, 1471, Archbishop Rokycan died, only a few weeks before his old ally King George, who died of dropsy on March 22 of the same year.
