But this dark picture had also its bright side. A struggling state, which hitherto had not tolerated the Jews, now became a new, though not very hospitable, home, where the Jewish race was rejuvenated. The Austrian exiles dispersed in various directions. Many sought protection in Moravia, Bohemia, and Poland. Others went to Venice and as far as the Turkish frontiers, others turned to Fürth, in Bavaria. Fifty families were received by Elector Frederick William, in the Mark of Brandenburg. This great prince, who laid the solid foundation for the future greatness of the Prussian monarchy, was not more tolerant than other princes of Louis XIV's century; but he was more clear-sighted than Emperor Leopold, and recognized that a sound state of finances is essential to the prosperity of a state, and that Jews retained somewhat of their old renown as financiers. In the Mark of Brandenburg no Jew had been allowed to dwell for a hundred years, since their expulsion under Elector John George. Frederick William himself took the step so difficult for many; he wrote (April, 1670) to his ambassador, Andrew Neumann, at Vienna, that he was inclined to receive into the electoral Mark from forty to fifty prosperous Jewish families of the exiles from Vienna under certain conditions and limitations. The conditions, made known a year later, proved in many points very harsh, but were more favorable than in other Protestant countries, as, for instance, in the bigoted city of Hamburg. The Jews might settle where they pleased in Brandenburg and in the duchy of Crossen, and might trade everywhere without hindrance. The burgomasters were directed to place no impediment in the way of their settlement and not to molest them. Every family had to pay eight thalers a year as a protective tax, a gold florin for every marriage, and the same for every funeral; on the other hand, they were freed from the poll-tax throughout the country. They might buy and build houses, on condition that after the expiration of a term they sell them to Christians. They were not permitted to have synagogues, but could have prayer-rooms, and appoint a school-master and a butcher (Shochet). This charter of protection was valid for only twenty years, but a prospect was held out that it would be prolonged by the elector or his successor. Of these fifty Austrian families, some seven settled in Berlin, and formed the foundation of the community afterwards so large and influential. One step led to another. Frederick William also admitted rich Jews from Hamburg, Glogau, and other cities, and thus communities sprang up at Landsberg and Frankfort-on-the-Oder.
