raise the money to support strikes. This system was replaced in 1901 because it was impractical. The 1901 system required every local union and the central committee to create strike funds. Local unions would receive support for strikes from Berlin under certain circumstances, and the central Business Committee's fund would be replenished by all member organizations in amounts proportional to their membership and the average wage of their members. This system, too, proved problematic because it penalized the larger, wealthier unions — especially the construction workers in Berlin who had higher wages but also higher costs of living. From 1901 to 1903, many small organizations joined the federation, yet the FVdG's membership fell as the punitive strike support system drove some larger unions out. In 1903, the federation not only changed its name to the Free Association of German Trade Unions but also decided to return to the old system of voluntary contributions. This system remained in place until 1914. The Business Committee worked to ensure that unions contributed as much as they could. Often the committee resorted to threatening unions with expulsion in order to raise funds for a strike. Fritz Kater called this a dictatorship necessary for the movement, but local organizations still had far more autonomy than their counterparts in other German labor federations. Radicalization and expulsion from the SPD During the first decade of the 20th century, the FVdG was transformed from a localist union federation into a syndicalist labor organization with anarchist tendencies. The process was initiated by the death of Gustav Keßler, the most important ideologue in the FVdG, in 1903. His role was largely assumed by the physician Raphael Friedeberg. In 1903, a dispute between the FVdG and the Free Trade Unions in Berlin led the party commission to intervene and to sponsor talks aimed at re-unification of the two wings of the German labor movement. At the meeting, the FVdG made a number of compromises, which led to member protests. Soon, over one-third of the members left the union. The 1903 FVdG congress elected a panel to continue negotiations with the Free Trade Unions. This panel demanded that the Free Trade Unions adopt localist organizational principles as a prerequisite for re-unification. The FVdG panel realized this demand was unrealistic, but hoped the expulsion of revisionists from the SPD during the debate on Eduard Bernstein's theses would strengthen their position. The impossibility of
