Introduction: The rise of the Comintern and the role of Leon Trotsky

Core Argument

The Communist International was founded in 1919 amidst the revolutionary wave unleashed by the October Revolution, with Lenin and Trotsky as its principal architects. Trotsky's central role in shaping the first four congresses was later systematically obscured by Stalinist mythology, yet his writings from this period demonstrate his indispensable contribution to constructing a genuinely revolutionary international. Marxists require such an organisation because capitalism is a global system; socialism cannot be confined to one country, as the Soviet Union's isolation tragically proved.

The betrayal of the Second International on 4 August 1914, when its leaders voted for war credits, had been long in preparation and necessitated a new International. The Zimmerwald Left, led by the Bolsheviks, provided its foundation, and the October Revolution gave decisive impetus to left-wing currents worldwide. The First Congress in March 1919 gathered revolutionary forces from across the globe, including colonial countries, and proclaimed the new International. Lenin insisted that international revolution was essential to prevent the Russian Revolution's destruction.

The Comintern's growth was rapid but uneven. Communist parties formed globally as revolutions swept the post-war world, emerging from the left wings of socialist parties in most countries, though in China the Communist Party was the first genuine working-class political organisation. Ultra-left tendencies plagued many fledgling parties, including Britain's, where leaders like Sylvia Pankhurst opposed Lenin's advice on parliamentarism. Through patient debate, the Comintern leadership won these parties to correct tactics. The twenty-one conditions, adopted by the Second Congress, were designed to purge opportunist elements, requiring party publications under elected leadership, removal of reformists from leading positions, and a complete break with reformism. Democratic centralism guaranteed internal debate but binding decisions.

Revolutionary optimism characterised the first two congresses, but the Third Congress addressed capitalism's temporary restabilisation and the necessary tactical shift. Trotsky warned against a mechanical conception of social revolution: expanded capitalist production simultaneously strengthens both proletariat and bourgeoisie, requiring correct strategy to win the majority. The United Front tactic, mandated by the Fourth Congress, demanded strict international discipline. On trade unions, the Comintern rejected splitting; Communists were to join existing unions to transform them from within. On the national question, Lenin insisted on the right of self-determination for all nations while subordinating national interests to the world revolutionary struggle, explicitly rejecting the Menshevik theory of stages that Stalin later revived.

After Lenin's death, bureaucratic degeneration destroyed workers' democracy in Russia. A privileged caste consolidated around Stalin, transforming the Bolshevik Party into a tool for defending bureaucratic privilege. Trotsky alone refused to capitulate, defending the first four congresses' lessons until his assassination in 1940. The Comintern became a counter-revolutionary force, applied disastrously from Spain to Chile, and was dissolved in 1943. The task remains building a force to end capitalism.
