The 4th World Congress of the Communist International was an assembly of delegates to the Communist International held in Petrograd and Moscow, Soviet Russia, between November 5 and December 5, 1922. A total of 343 voting delegates from 58 countries were in attendance. The 4th World Congress is best remembered for having amplified the tactic of the United Front into a fundamental part of international Communist policy. The gathering also elected a new set of leaders to the Comintern's governing body, the Executive Committee of the Communist International (ECCI).
