 The FVdG 's disillusionment with the social democratic movement deepened during the mass strike debate . The role of the general strike for the socialist movement was first discussed within the FVdG in 1901 . At the SPD 's 1903 congress in Dresden , Raphael Friedeberg proposed discussing the topic , but his proposal was rejected by the congress . The following year , a proposal by Wilhelm Liebknecht and Eduard Bernstein to initiate debate on the topic was accepted , since they had distanced themselves from Friedeberg 's positions .
