many German states stripped Jews of their civil rights. In the Free City of Frankfurt, only 12 Jewish couples were allowed to marry each year, and the 400,000 florins the city's Jewish community had paid in 1811 for its emancipation was forfeited. After the Rhineland reverted to Prussian control, Jews lost the rights Napoleon had granted them, were banned from certain professions, and the few who had been appointed to public office before the Napoleonic Wars were dismissed. Throughout numerous German states, Jews had their rights to work, settle, and marry restricted. Without special letters of protection, Jews were banned from many different professions, and often had to resort to jobs considered unrespectable, such as peddling or cattle dealing, to survive. A Jewish man who wanted to marry had to purchase a registration certificate, known as a Matrikel, proving he was in a "respectable" trade or profession. A Matrikel, which could cost up to 1,000 florins, was usually restricted to firstborn sons. As a result, most Jewish men were unable to legally marry. Throughout Germany, Jews were heavily taxed, and were sometimes discriminated against by gentile craftsmen. As a result, many German Jews began to emigrate. The emigration was encouraged by German-Jewish newspapers. At first, most emigrants were young, single men from small towns and villages. A smaller number of single women also emigrated. Individual family members would emigrate alone, and then send for family members once they had earned enough money. Emigration eventually swelled, with some German Jewish communities losing up to 70% of their members. At one point, a German-Jewish newspaper reported that all the young Jewish males in the Franconian towns of Hagenbach, Ottingen, and Warnbach had emigrated or were about to emigrate. The United States was the primary destination for emigrating German Jews. The Revolutions of 1848 swung the pendulum back towards freedom for the Jews. A noted reform rabbi of that time was Leopold Zunz, a contemporary and friend of Heinrich Heine. In 1871, with the unification of Germany by Chancellor Otto von Bismarck, came their emancipation, but the growing mood of despair among assimilated Jews was reinforced by the antisemitic penetrations of politics. In the 1870s, antisemitism was fueled by the financial crisis and scandals; in the 1880s by the arrival of masses of Ostjuden, fleeing from Russian territories; by the 1890s it was a parliamentary presence, threatening anti-Jewish laws. In 1879 the Hamburg
