Editor’s Note:¶
Core Argument¶
The Third Congress of the Comintern, convening in Moscow from 22 June to 12 July 1921, marked a decisive turning point in the strategy of the international communist movement. With 509 delegates representing forty-eight countries—rising to 603 by the close—the Congress was dominated by a fierce struggle over revolutionary tactics in the aftermath of the post-war revolutionary wave’s ebb. The core narrative thrust of this editor’s note is to establish the Congress as the arena where the Bolshevik leadership, led by Lenin and Trotsky, defeated the ultra-leftist “Left Communists” who threatened to isolate the movement from the mass of workers.
The agenda was comprehensive, covering the world economic crisis, the German and Italian questions, trade union strategy, the Russian party’s tactics, and the Eastern question. But the central conflict revolved around the report on the tactics of the Communist International, delivered by Radek, and the broader orientation of the movement. The “Left Communists,” strongly represented and at one point appearing to hold a majority, advocated for a sectarian, adventurist line that rejected participation in reformist trade unions and parliamentary activity. Against this, Lenin demonstratively announced he was with the “Right Wing,” a polemical positioning that signalled his defence of a united front strategy and the necessity of winning the majority of the working class through patient, flexible work within existing mass organisations. Trotsky’s report on the world economic crisis and the new tasks of the CI provided the theoretical underpinning for this shift, arguing that the immediate revolutionary situation had passed and that communists must now prepare for a longer struggle.
The note draws on the immediate historical context of the failed German March Action of 1921, which had been championed by the ultra-leftist German Communist Workers Party (KAPD). The inclusion of the KAPD and the Italian question on the agenda reflects the Comintern’s need to discipline and correct these sectarian deviations. The line of Lenin and Trotsky finally carried the day, establishing the tactical orientation that would guide the Comintern through the coming period of relative stabilisation. The editor’s note thus serves as a concise record of a pivotal congress where the Bolshevik centre reasserted its authority against leftist infantilism, securing a strategic retreat from putschism toward mass work.
