The relations between the Jews and the "third estate," the burghers, did not improve in the reign of Sigismund Augustus, but they assumed a more definite shape. The two competing agencies, the magistracies and the Kahals, regulated their mutual relations by means of compacts and agreements. In some cities, such as Cracow and Posen, these compacts were designed to safeguard the boundaries of the ghetto, outside of which the Jews had no right to live; in Posen the Jews were even forbidden to increase the number of Jewish houses over and above a fixed norm (49), with the result that they were obliged to build tall houses, with several stories. In other cities, among which was included the city of Warsaw,[51] the magistracies managed to obtain the so-called privilege _de non tolerandis Judaeis_, _i. e._ the right of either not admitting the Jews to settle anew, and confining those already settled to special sections of the city, away from the principal streets, or keeping the Jews away from the city altogether, allowing only the merchants to come on business and stay there for a few days. However, in the majority of Polish cities the protection of the King secured for the Jews equal rights with the other townspeople. For, as one of the royal edicts puts it, "inasmuch as the Jews carry all burdens in the same way as the burghers, their positions must be alike in everything, except in religion and jurisdiction." In some places the King even went so far as to forbid the holding of the weekly market-day on Saturday, to safeguard the commercial interests of the Jews, who refused to do business on their day of rest.
