Having accepted the Polish crown, Casimir was resolved to rule independently and to disregard the designs of the all-powerful clergy. Shortly after his coronation, in August, 1447, while the King was on a visit to Posen, the city was devastated by a terrible fire. During the conflagration the ancient original of the charter which Casimir the Great had bestowed upon the Jews was lost. A Jewish delegation from the communities of Posen, Kalish, and other cities petitioned the King to restore and ratify the old Jewish privileges, on the basis of copies of the charter which had been spared. Casimir readily granted the request of the deputies. "We desire"--he announces in his new charter--"that the Jews, whom we wish to protect in our own interest as well as in the interest of the royal exchequer, should feel comforted in our beneficent reign." Corroborating as it did all the rights and privileges previously conferred upon the Jews--liberty of residence and commerce, communal and judicial autonomy, inviolability of life and liberty, protection against groundless charges and attacks--the charter of Casimir IV. was a direct protest against the canonical laws only recently reissued for Poland by the Council of Kalish, and for the whole Catholic world by the great Council at Basle. In opposition to the main trend of the Council resolutions, the royal charter permitted the Jews to associate with Christians, and exempted them from the jurisdiction of the ecclesiastic law courts (1453). The King's liberalism aroused the resentment of the Catholic clergy. The leader of the clerical party was the energetic Archbishop of Cracow, Cardinal Zbignyev Oleshnitzki, who openly headed the forces arrayed in opposition to the King. He denounced Casimir bitterly for granting protection to the Jews, "to the injury and insult of the holy faith." Do not imagine--Oleshnitzki writes to the King in May, 1454--that in matters touching the Christian religion you are at liberty to pass any law you please. No one is great and strong enough to put down all opposition to himself when the interests of the faith are at stake. I therefore beg and implore your Royal Majesty to revoke the aforementioned privileges and liberties. Prove that you are a Catholic sovereign, and remove all occasion for disgracing your name and for worse offenses that are likely to follow. In his letter Oleshnitzki refers to the well-known agitator and Jew-baiter, the Papal Legate Capistrano, who had come to Poland from Germany in the fall of 1453. With this "scourge of the Jews" as his ally Oleshnitzki started a campaign against Jews and heretics (or Hussites). On his arrival in Cracow Capistrano delivered on the market-place incendiary speeches against the Jews, and demanded of the King persistently to revoke the "godless" Jewish privileges, threatening him, in case of disobedience, with the tortures of hell and terrible misfortunes for the country.
