Soviet Union, Politics

The Soviet authorities decide to dissolve the Comintern to 'prove' to the West that Russia no longer has any expansionist aims. The dissolution is announced on May 22.

In a gesture designed to reassure his Western Allies that the USSR is no longer trying to foment world revolution, Stalin dissolved the Comintern. The latter, founded in 1919 by Lenin and the Bolsheviks, is dedicated 'by all available means, including armed force, for the overthrow of the international bourgeoisie and for the creation of an international Soviet republic as a transition stage to the complete abolition of the State'. The Americans in particular were keen for this organization to be disbanded.
