The League of Jewish Women in Germany (, JFB) was founded in 1904 by Bertha Pappenheim. Pappenheim led the JFB throughout the first twenty years of its existence, and remained active in it until her death in 1936. The JFB became increasingly popular through the 20th century. At its peak in 1928, the organization had 50,000 members from 34 local branches and 430 subsidiary groups. At the time, the JFB was Germany's third largest Jewish organization, with 15-20% of Jewish women in Germany becoming members. Growth out of the Women's Movement The JFB followed the 1899 founding of the German Evangelical Women's Association (), as well as the founding in 1903 of the German Catholic Women's Association (). It was the part of the period of activity some call "First-wave feminism", in which women in some countries, including Germany, led movements aimed to increase women's rights. The foundation of the JFB shaped a distinct movement situated at the intersection of German society and Jewish tradition. From 1907 the JFB was a member of the Union of German Feminist Organizations (, BDF), which had been developed as an umbrella organization for the various women's associations. Goals and work The JFB was a community with a primary interest of improving women's experiences in the Jewish community. It was open about its desire to bring women into closer contact with Jewish tradition. Many members of the organization came from relatively assimilated Jewish families who had drifted far from tradition, and some were encouraged by their husbands to further conceal their Jewish identities. Some of these women reacted by developing a feminist practice of tzedakah, or the charitable giving mandated by Jewish law. The philanthropic contributions from local women's organizations supported centralized social outreach as well as the maintenance of relationships with international collaborators. This work led to the founding of the Central Office for the Welfare of Jews in Germany (ZWSt) in 1917. The organization, particularly in its early years, focused on fighting for women's right to vote within the Jewish community. The organization made combating antisemitism a main priority, even though it put less emphasis on the issue as many Jewish men's groups. The JFB provided social and educational resources for Jewish women and strove to end what was defined as "female slavery", prostitution, and moral degradation in Germany and abroad. Pappenheim traveled to Eastern Europe on various occasions, which motivated her
