The Zimmerwald Conference¶
Core Argument¶
The Zimmerwald Conference chapter argues that the Bolsheviks, despite lacking a formal international apparatus, consistently worked toward a revolutionary International, rejecting both social-chauvinism and the pacifist centrism that dominated the anti-war left. Lenin insisted on a decisive political break from the right while maintaining participation within existing mass workers’ organisations, instructing Bolsheviks abroad to join local socialist parties to prevent the demoralisation of exile isolation. This dual tactic—engagement without compromise—laid the groundwork for the Zimmerwald Left and, ultimately, the Communist International.
The chapter traces the failed preliminary attempts at international coordination: the Lugano meeting of 1914, where Italian and Swiss Social Democrats passed pacifist resolutions and appealed to the International Socialist Bureau, a move Lenin rejected; the Stockholm Congress of Swedish Social Democrats in November 1914, where Shlyapnikov defended the Bolshevik position against Karl Branting’s abstentionism, backed by leftist Karl Höglund; and the Copenhagen conference of neutral states in January 1915, which Lenin dismissed as pointless. Worse was the London conference of Entente socialists in February 1915, where Litvinov attempted to read a Bolshevik anti-war resolution before being silenced and walking out. These episodes illustrate the chasm between revolutionary internationalism and the impotent, hand-wringing pacifism Lenin detested.
The Zimmerwald Conference itself, convened in September 1915 by centrists Grimm and Balabanova, assembled only 38 delegates. Lenin organised the Zimmerwald Left as a minority within a minority—eight delegates including Zinoviev, Radek, Platten, and Höglund. The centrist majority, including Grimm, Lazzari, and Rakovsky, recoiled at the prospect of a Third International. Karl Liebknecht’s prison letter, read aloud, called for “civil war, not civil peace,” echoing Lenin’s slogan. Lenin signed the Zimmerwald manifesto, written by Trotsky, but criticised it not for what it said, but for what it omitted. He saw the conference as “the first step” toward an ideological break with opportunism, while warning that most delegates would soon vacillate rightward.
The chapter draws on Trotsky’s retrospective analysis comparing the war period to the post-1905 reaction, when cadres melted away and the movement seemed impoverished, yet new moods fermented beneath the surface. Shlyapnikov’s memoirs confirm that news of Zimmerwald reached Russian workers, encouraging cells unaffiliated with the Bolsheviks. The chapter concludes by surveying the crystallisation of revolutionary currents in Germany (Spartacus, Rühle), Austria (Karl Marx Club), France (left MPs), Britain (BSP’s Salford Conference), Italy (Serrati, Gramsci), Switzerland, and Bulgaria (tesnyaki). The polemical target is twofold: the open social-chauvinists who acted as conscious agents of the ruling class, and the centrists who preserved unity with the right under the guise of internationalism. Lenin’s insistence on clarity over unity, and his refusal to paper over cracks, drives the chapter’s narrative.
