The 3rd World Congress of the Comintern was held in Moscow on 22 June–12 July 1921. The third official meeting of the Communist International included delegations from more than 50 different national structures and took place in the back-drop of two major events; the failure of the German revolution and the introduction of New Economic Policy in Soviet Russia. The main language of the congress was German, with three further working languages: French, English and Russian (of the three, French being predominant).
