To Comrades of the Spartacus League¶
Core Argument¶
In this open letter of March 1919, Trotsky seizes the opportunity to address the Spartacus League directly, framing the German revolution as the long-awaited confirmation of Bolshevik strategy and the definitive refutation of centrist and reformist Marxism. The core argument is that the Russian Revolution has unfolded exactly according to the historical logic Marxists ought to have recognised, and that those who now denounce it—above all Karl Kautsky—have abandoned Marxism for pedantic, schoolmasterly formalism.
Trotsky’s key polemical target is Kautsky, whom he accuses of a catastrophic theoretical collapse worse than the Social Democratic vote for war credits on 4 August 1914. He recalls that in 1905-06, under Rosa Luxemburg’s influence, Kautsky understood that the Russian revolution could not stop at a bourgeois-democratic republic but must lead to the dictatorship of the proletariat. Kautsky then accepted that the proletariat, having taken power, could not postpone its action for the sake of peasant voting patterns in a Constituent Assembly, but would instead use state power to enlighten the backward masses. Now, Trotsky charges, Kautsky refuses to recognise the revolution he himself once predicted, because it arrived without democratic formalities. This is not Marxism but philistinism: the schoolmaster who has taught spring from a textbook and fails to recognise it in nature.
Trotsky also rebuts the accusation, levelled by Bernstein and the Independent Social Democrats, that the Bolsheviks were wrong to conclude the Brest-Litovsk peace with German militarism. He argues that those who proclaimed the German revolution impossible while demanding Russia continue the war alongside British imperialism displayed stunning political stupidity. The German workers have since proved the Bolsheviks correct by overthrowing the monarchy. A further slander—that the Soviet government plans to invade East Prussia—Trotsky dismisses as a fiction circulated by political charlatans. The Red Army’s task, he insists, is to defend socialist power on Russian soil, not to substitute for the German proletariat’s own revolutionary struggle.
The letter draws on the shared heritage of German Marxism, invoking the Hegelian metaphor of history’s mole digging underground. Trotsky positions himself and the Spartacists as the true heirs of Marx, against Kautsky’s ossified orthodoxy and Bernstein’s opportunism. The closing salute to Liebknecht and Luxemburg, whose bodies dot the road of struggle, anchors the argument in the immediate, bloody reality of the German revolution.
