The history of the Communist Party in the Weimar Republic can be described as a history of growing dependence on Moscow, the Communist International and its Executive Committee (ECCI), which was founded in March 1919. If the party was able to maintain its independence until 1920 and to position itself as a communist mass party after the merger with the left wing of the USPD, then the party came under increasing influence from the ECCI and its emissaries in 1921. A first phase in the subordination of the KPD to Moscow can be seen in 1921, when the March Uprising, which was caused by ECCI emissaries, led to a party crisis including the loss of leading Communist politicians. The example of Ernst Däumig (1866–1922), who together with Paul Levi led the KPD as co-chairman in 1920/21, will focus on several issues that are also relevant to the history of the revolutionary workers’ movement. The article will address the party’s appeal to representatives of the left wing of the USPD to join the Comintern and, thereby, the KPD and, finally, the failure of this cooperation and its impact on former USPD members.
