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.
