"The Communist International (Comintern), also known as the Third International (1919–1943), was an international organization that advocated world communism. It was controlled by the Soviet Union. The Comintern resolved at its Second Congress to "struggle by all available means, including armed force, for the overthrow of the international bourgeoisie and the creation of an international Soviet republic as a transition stage to the complete abolition of the state". The Comintern was preceded by the 1916 dissolution of the Second International.
The Comintern held seven World Congresses in Moscow between 1919 and 1935. During that period, it also conducted thirteen Enlarged Plenums of its governing Executive Committee, which had much the same function as the somewhat larger and more grandiose Congresses. As the worldwide communist movement split internally over Leninism and Soviet atrocities, Cominterm-affiliated parties that received substantial funding from the Soviet Union attempted to defend Soviet policy (including the Molotov–Ribbentrop Pact), suppress rival left-wing movements, and gather intelligence on behalf of Soviet intelligence agencies. After the invasion in 1941, Comintern activities in Allied nations were halted; in 1943, Joseph Stalin, head of the Soviet Union, dissolved the Comintern as a gesture of goodwill to his key wartime allies, the United States and the United Kingdom. However, according to declassified Soviet archives in the 1990s, prior to the dissolution, the Moscow NKVD sent "detailed instructions for handling intelligence sources" to all Comintern stations in Western democracies so that they may continue their espionage for the Soviet Union." - (en.wikipedia.org 24.12.2020)
