Communist International followed by Cominform
Successor organizations
The Research Institutes 100 and 205 worked for the International and later were moved to the International Department of the Central Committee of the Communist Party of the Soviet Union, founded at roughly the same time that the Comintern was abolished in 1943, although its specific duties during the first several years of its existence are unknown.Following the June 1947 Paris Conference on Marshall Aid, Stalin gathered a grouping of key European communist parties in September and set up the Cominform, or Communist Information Bureau, often seen as a substitute to the Comintern. It was a network made up of the communist parties of Bulgaria, Czechoslovakia, France, Hungary, Italy, Poland, Romania, the Soviet Union and Yugoslavia (led by Josip Broz Tito and expelled in June 1948). The Cominform was dissolved in 1956 following Stalin's 1953 death and the 20th Congress of the Communist Party of the Soviet Union.
While the communist parties of the world no longer had a formal international organization, they continued to maintain close relations with each other through a series of international forums. In the period directly after the Comintern's dissolution, periodical meetings of communist parties were held in Moscow. Moreover, World Marxist Review, a joint periodical of the communist parties, played an important role in coordinating the communist movement up to the break-up of the Eastern Bloc in 1989–1991.
