while Sigismund raised him to the exalted position of Chancellor of the Lithuanian Exchequer. Abraham and his offspring were soon lost in the ranks of the higher Polish nobility. In agricultural Lithuania with its patriarchal conditions of life the antagonism between the classes was in its infancy, and as a result the right of the Jews to freedom of transit and occupation was but rarely contested. They lived in the towns and villages, and were not yet so sharply marked off, in language and mode of life, from the Christian population as they became afterwards. The Jewish communities of Brest, Grodno, Pinsk, and Troki, the last consisting principally of Karaites, who had a municipality of their own, were important Jewish centers in the Duchy, and enjoyed considerable autonomy. The rabbi of Brest, Mendel Frank, received from the King extensive administrative and judicial powers, including the right of imposing the _herem_ and other penalties upon the recalcitrant members of the community (1531). In the large cities of Poland proper the position of the Jews was not nearly so favorable. Here commercial life had attained a higher stage of development than in Lithuania, and in many lines of business the Jews competed with the Christians. Taking advantage of the autonomy granted to the estates in the shape of the Magdeburg Law, the Christian business men and handicraftsmen, represented by their magistracies and trade-unions, were constantly endeavoring to restrict their rivals in their commercial pursuits. This was particularly the case in Posen, Cracow, and Lemberg, the leading centers respectively of the three provinces of Great Poland, Little Poland, and Red Russia (Galicia). In Posen the Jews were hampered by the burgomaster and the aldermen in carrying on their business or in displaying their goods in stores outside the Jewish quarter. When the Jews protested to the King, he warned the authorities of Posen not to subject their rivals to any hardships or to violate their privileges (1517). The Christian merchants retorted that the Jews occupied the best shops, not only in the center of the town, but also on the market-place, where formerly only "prominent Christian merchants, both native and foreign [German], had been doing business," and where, in view of the concentration of large masses of Christians, the presence of Jews might lead to "great temptations," and even to seduction from the path of the "true faith." The reference to religion, used as a cloak for commercial greed, did not fail to impress the devout Sigismund, and he forbade the Jews to keep stores on the market-place (1520). The professors of Christian love in Posen similarly forbade their Jewish fellow-citizens to buy foodstuffs and other articles in the market until the Christian residents had completed their purchases. A little later the King, in consequence of the influx of Jews into Posen, gave orders that no new Jewish settlers
