Karl Marx had demonstrated that the collapse of capitalism is inevitable and Lenin showed that the socialist transition would begin in Russia, capitalism’s weakest link. The Bolshevik seizure of power in Russia is therefore seen by its supporters as merely the first stage of a revolutionary wave that will soon sweep the world. Unrest in Germany and elsewhere indicates working people are ripe for revolution: perhaps only the slightest push is needed for the capitalist house of cards to fall.
To hasten socialist revolution, the Bolsheviks (now renamed the Russian Communist Party) call a meeting of sympathetic socialist parties in Moscow. Their aim is to replace the now largely defunct Second International of socialist parties with a new Third International, one that will be explicitly communist and which will allow the various parties to better coordinate their efforts to overthrow capitalism. And, crucially, this Communist International will be under Moscow’s control, to ensure that the affiliated parties do not slip into unsound thinking or act in ways contrary to the interests of Soviet Russia.
The founding congress of the Communist International opens today. Transport difficulties and the Allied blockade of Soviet Russia mean that it is difficult for delegates to travel to Moscow; many of those present are exiles who have been living in Russia for some time. Leading Russian communists such as Kollontai, Trotsky and Lenin himself present material to the congress. Zinoviev is appointed chairman of its executive. He reports confidently: “in a year, the whole of Europe will be communist”.
