Karl Kautsky
Orthodox Marxist theorist and leading figure of the SPD.
Karl Kautsky, born in Prague in 1854 and educated in Vienna, became one of the most authoritative figures in Marxist theory following the death of Friedrich Engels. He founded the journal *Die Neue Zeit* in 1883 and edited it for thirty-five years, and during a five-year stay in London he became a close friend of Engels. After Germany’s Anti-Socialist Laws were repealed, Kautsky wrote the theoretical section of the SPD’s 1891 Erfurt Program, and his commentary on it, *The Class Struggle*, became a widely circulated summary of Marxist thought. His framework reinterpreted Marx’s critique of political economy into a set of historical-empirical laws, predicting the inevitable concentration of capital, the polarisation of society, and the immiseration of the working class. Kautsky advocated a gradualist, evolutionary path to socialism, arguing that revolution was inevitable but could not be forced prematurely; the socialist party’s role was to organise workers, win reforms, and improve conditions through bourgeois parliamentary democracy until material conditions were ripe for transition. This centrist stance placed him between reformism and revolutionary radicalism, leading him to defend orthodoxy against Eduard Bernstein’s revisionism and to oppose Rosa Luxemburg’s emphasis on revolutionary spontaneity. His influence collapsed after 1914 when he opposed the SPD’s support for the German war effort, co-founding the anti-war Independent Social Democratic Party of Germany in 1917. After the war, he denounced the October Revolution as a premature coup that established a new dictatorship, arguing the Bolsheviks betrayed the democratic principles essential to socialism. He rejoined the SPD in 1922 but his influence steadily declined, and he fled to Amsterdam after the 1938 Anschluss, dying there that same year.

Reader's Guide
Kautsky’s orthodox Marxism was defined by a gradualist, evolutionary path to socialism. He held that a socialist revolution was inevitable but could not be forced prematurely; instead, a socialist party’s role was to organise the working class, win political reforms, and improve workers’ lives through the institutions of bourgeois parliamentary democracy until material conditions were ripe for transition. This centrist stance placed him in conflict with both Eduard Bernstein’s revisionism and Rosa Luxemburg’s revolutionary spontaneity. His pre-war influence was immense, shaping Marxism across Europe and particularly in the Russian Empire, where Vladimir Lenin regarded him as the leading authority on Marxist theory. After 1914, his influence collapsed. He opposed the SPD’s support for the German war effort, broke with the party, and co-founded the anti-war USPD. Following the war, he became a prominent critic of the October Revolution, denouncing it as a premature coup that established a new dictatorship, arguing that Bolshevik methods betrayed the democratic principles essential to socialism. He rejoined the SPD in 1922 but his influence steadily declined. Vilified by Leninists as a “renegade”, Kautsky is viewed by others as a consistent proponent of democratic socialism whose work continues to influence modern currents.
