Communist International

The Communist International (abbreviated as Comintern), also known as the Third International, was a Marxist political international that advocated world communism and existed from 1919 to 1943. Emerging from the collapse of the Second International during World War I, it was founded at a congress in Moscow convened by Vladimir Lenin and the Russian Communist Party (Bolsheviks) (RCP), which aimed to create a new international body committed to revolutionary socialism and the overthrow of capitalism worldwide.

Initially, the Comintern operated with the expectation of imminent proletarian revolutions in post-war Europe, particularly in the former German Empire, which were seen as crucial for the survival and success of the Russian Revolution. Its early years were characterized by attempts to foment and coordinate revolutionary uprisings and the establishment of disciplined communist parties across the globe, often demanding strict adherence to the "Twenty-one Conditions" for admission. As these revolutionary hopes faded by the early 1920s, the Comintern's policies shifted, notably with the adoption of the "united workers' front" tactic, aiming to win over the working masses from reformist socialist parties. Throughout the 1920s, the Comintern underwent a process of "Bolshevization", increasing the centralization of its structure and the dominance of the RCP within its ranks. This process intensified with the rise to power of Joseph Stalin in the Soviet Union.
