collaboration with communists. Nevertheless, the FVdG's Rhineland and Westphalia section merged with left communist unions to form the Free Workers' Union (FAU) in September 1919. Syndicalists from the FVdG were the biggest and most dominant faction in the FAU. The FAU's statutes mostly reflected compromises by the federation's member unions, but also reflected the FVdG's significant influence. Soon it was decided to complete the merger in Rhineland and Westphalia on a national level. The FVdG's 12th congress, held December 27 to 30, became the Free Workers' Union of Germany's (FAUD) founding congress. Most left communists (including the influential veteran member Karl Roche) had already quit or were in the process of leaving the FAU in Rhineland and Westphalia by this point. The majority of them would join the General Workers' Union of Germany (AAUD), which was founded in February 1920. Without the left communists to oppose its adoption, Rocker's thoroughly anarchist "Prinzipienerklärung des Syndikalismus" ("Declaration of Syndicalist Principles"), which the Business Commission had charged him with drafting, became the FAUD's platform without much controversy. The FAUD also rejected the dictatorship of the proletariat and other Marxist terms and ideas. According to the Business Commission, the congress was attended by 109 delegates representing 111,675 workers, twice as many as were claimed just four and a half months earlier.
