be admitted into the city, and that no houses owned by Christians be sold to them, without the permission of the Kahal elders. The Jews were to be restricted to definite quarters and to be denied the right of building their houses among those belonging to Christians (1523). The same was the case in Lemberg. Yielding to the complaints of the magistracy about the competition of the Jews, the King restricted their freedom of commerce in several particulars, barring them from selling cloth in the whole of [Red] Russia and Podolia, except at the fairs, and limiting their sale of horned cattle to two thousand head per year (1515). The Piotrkov Diet of 1521 passed a law confining the trade of the Lemberg Jews to four articles, wax, furs, cloth, and horned cattle. These restrictions were the result of the widespread agitation which the pious Christian merchants had been conducting against their business rivals of other faiths. The magistracies of the three cities of Posen, Lemberg, and Cracow, attempted to form a coalition for the purpose of carrying on a joint economic fight against Jewry. In Cracow and its suburb Kazimiezh[47] the Jews had to endure even harsher restrictions in business than in the other two metropolitan centers of Poland. Competition in business occasionally resulted in physical violence and street riots. Anti-Jewish attacks were taking place in Posen and in Brest-Kuyavsk,[48] and outbreaks were anticipated in Cracow. Representatives of the last Jewish community made their apprehensions known to the King. Sigismund issued a decree in 1530 denouncing in vehement terms the insolence of the rioters, who were hoping for immunity, and rigorously forbidding all acts of violence, under penalty of death and confiscation of property. To allay the fears of the Jews he ordered the burghers of Cracow to deposit the sum of ten thousand gulden with the exchequer as security for the maintenance of peace and safety in the city. The burgomasters, aldermen, and trade-unions were warned by the King that in all their differences with Jews "they should proceed in a legal manner, and not by violence, by resorting to force of arms and inciting disorders." The King was powerless, however, to shield the Jews against other unpleasant manifestations of the Polish class _régime_, such as the extortions of the officials. The highest dignitaries of the court no less than the local administration were ever ready to fish in the troubled waters of the conflict of classes. The second wife of Sigismund, Queen Bona Sforza, an avaricious Italian princess, sold the offices of the state to the highest bidder, while the courtiers and voyevodas were just as venal on their own behalf. The queen's favorite, Peter Kmita, Voyevoda of Cracow and Marshal of the Crown, managed to accept bribes simultaneously from the Jewish and the Christian merchants, who lodged complaints against each other, by promising both sides to defend their interests before the Diet or the King.
