Created by Sergei Biets in 1990 as the Russian section of the Committee for a Workers' International (CWI). CWDIS considered itself a direct successor of the Union of Bolshevik-Leninists, founded by Leon Trotsky in 1928. The organization was engaged in the distribution of its propaganda materials and actively participated in the events of 1991 and 1993 in Moscow, opposed the introduction of the "anti-worker" Code of Labor Laws. The committee published the newspaper "Workers' Democracy". In 1993, the organization split over the issue of membership in the CWI. As a result, two groups with the same name were formed.
