The championship of Jewish interests passed by degrees from the hands of royalty into those of the wealthy parliamentary Shlakhta. Though more and more permeated by clerical tendencies, the fruit of Jesuit schooling, the nobility in most cases held its protecting hand over the Jews, to whom it was tied by the community of economic interests. The Jewish tax-collector in the towns and townlets, which were privately owned by the nobles, the Jewish _arendar_[56] in the village, who procured an income for the _pan_[57] from dairying, milling, distilling, liquor-selling and other enterprises--they were indispensable to the easy-going magnate, who was wont to let his estates take care of themselves, and while away his time in the capital, at the court, in merry amusements, or at the tumultuous sessions of the national and provincial assemblies, where politics were looked upon as a form of entertainment rather than a serious pursuit. This Polish aristocracy put a check on the anti-Semitic endeavors of the clergy, and confined the oppression of the Jews within certain limits. Even the devout Sigismund III., who was subject to Jesuit influence, continued the traditional rôle of Jewish protector. In 1588, shortly after his accession to the throne, he confirmed, at the request of the Jews, their right of trading in the cities, though not without certain restrictions which the demands of the Christian merchants had forced upon him.
Nevertheless the economic struggle in the cities continues with ever-increasing fury, manifesting itself more and more in the shape of malign religious fanaticism. In many cities the municipalities arrogate to themselves judicial authority over the Jews--the authority of the wolves over the sheep--contrary to the fundamental Polish law, which places all litigation between Jews and Christians under the jurisdiction of the royal officials, the voyevodas and starostas. The king, appealed to by the injured, has frequent occasion to remind the magistracies that the Jews are not to be judged by the Magdeburg Law, but by common Polish law, in addition to their own rabbinical courts for internal disputes. A pronouncement of this nature was issued, among others, by King Sigismund III., when the Jews of Brest appealed to him against the local municipality (1592). Their appeal was supported by the head of the Jewish community, Saul Yudich (son of Judah), contractor of customs and other state revenues in Lithuania, who wielded considerable influence at the Polish court. He bore the title of "servant of the king," and was frequently in a position to render important services to his coreligionists.[58] But where the Jewish masses were not fortunate enough to possess such powerful advocates in the persons of the big tax-farmers and "servants of the king," their legitimate interests were frequently trampled upon. The burghers of Vilna, in their desire to dislodge their Jewish competitors from the city, did not stop at open violence. They demolished the synagogue, and sacked the Jewish residences in the houses owned by the Shlakhta (1592). In Kiev, where the Jews had been settled in the Old Russian period,[59] the burghers were endeavoring to secure from the King the privilege _de non tolerandis Judaeis_ (1619).
