After the German revolution in November, when an Estonian government took office, the party together with support of Soviet troops attempted an armed attack against the new state. However, by this time the support for the party had waned, and it failed to mobilize mass support for revolutionary warfare. An Estonian Workers' Commune was set up, but with limited real influence. At this time the party branch had been reorganized into the "Central Committee of the Estonian Sections of the RCP(b)" (). After the war a reorientation was found to be necessary (since Estonia was now an independent state) by the central leadership of the RCP(b) and thus on the November 5, 1920 the Communist Party of Estonia (EKP) was founded as a separate party. In the rigged 1940 Riigivolikogu election, the Communist Party ran within the Estonian Working People's Union bloc.
