The first Communist International meets in Moscow.

The Communist International, abbreviated as Comintern and also known as the Third International, was a political international which existed from 1919 to 1943 and advocated world communism. Emerging from the collapse of the Second International during World War I, the Comintern was founded in March 1919 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.
