Founder of the ADAV, Germany's first workers' party

"Das eiserne und grausame Gesetz" — the iron and cruel law Lassalle said held wages down to bare subsistence (1863)

A lawyer and agitator from a Jewish merchant family in Breslau. In May 1863 he founded the General German Workers' Association (ADAV) at Leipzig and was elected its president for five years, arguing that universal suffrage would turn the state toward funding producers' co-operatives and so toward socialism. That same year he met Bismarck in secret to sound out an alliance between the workers and the Prussian monarchy, which drew Marx's deep suspicion. In 1864 he was shot in a duel over a marriage and died three days later outside Geneva. Eleven years afterwards his programme supplied the frame of the Gotha unity programme.

A woodturner's apprentice who co-founded the Social Democratic Workers' Party with Wilhelm Liebknecht in 1869 and, through the Gotha unity congress of 1875, built the SPD into the world's largest socialist party. Under the Anti-Socialist Laws (1878–1890) he ran the illegal party paper from Zurich exile and held the underground organisation together; he steered the adoption of the Erfurt Programme (1891), which became the Marxist benchmark for European social democracy, and led the orthodox defence against Eduard Bernstein's revisionism.

Veteran founder of French Marxist socialism who entered the Union sacrée government in 1914

After war began in 1914, Guesde left the socialist antiwar camp and entered the French government as minister without portfolio. At Stuttgart in 1907 he had rejected special antiwar measures apart from the socialist struggle; wartime office brought that position into government practice.

A journalist exiled for supporting the Paris Commune, he drafted the programme of the French Workers’ Party with Marx in 1880 and became the standard-bearer of French Marxism. He long opposed the reformist Jaurès and took part in founding the unified Socialist Party (SFIO) in 1905. At Stuttgart in 1907 he argued that class struggle would abolish war and that no special anti-war action was needed. In August 1914, seeing France itself in danger, he joined the Union sacrée government as a minister without portfolio and stayed until 1916.

From a narodnik revolver to Marxist criticism, half a century of one woman's revolutionary life

On 31 March 1878, the jury returned a unanimous acquittal. The crowd lifted Zasulich onto their shoulders and marched through the streets of St. Petersburg. The tsarist government ordered her rearrest at once, but the shot she had fired already echoed across Europe.

In 1878 she shot St. Petersburg governor Trepov, and a jury acquitted her. That single shot detonated public fury against tsarist autocracy, and all Europe learned her name. Yet Zasulich was the first to grasp that terror was a dead end, and turned to Marxism. In 1883 she co-founded the Emancipation of Labour group (Russia's first Marxist organisation) with Plekhanov and Axelrod. She served on the Iskra editorial board, represented Russia at three congresses of the Second International, and became one of Russia's earliest Marxist literary critics. A Menshevik, she opposed the October Revolution of 1917 and died of pneumonia under Bolshevik rule.

The great unifier of the Russian revolutionary movement, from the Chaikovtsy to the Left SRs

'I have complete discord with Lenin... I no longer believe in Lenin' — in 1919, on the eve of exile, breaking with the Bolsheviks after half a century of shared struggle.

Mark Natanson was a pivotal organizer who built the institutional backbone of the Russian revolutionary movement across half a century: co-founding the Circle of Tchaikovsky, Land and Liberty, and the People's Rights Party, and serving on the Central Committee of the Socialist Revolutionary Party. Known as the 'Ivan Kalita of the revolution' for his talent in unifying dispersed circles, he stood with Lenin as an internationalist at the Zimmerwald and Kienthal conferences during the First World War. In 1917 he led the formation of the Left SRs and later the Party of Revolutionary Communism, backing the Bolsheviks through the October Revolution, but grew disillusioned as the regime turned toward one-party dictatorship, leaving the words 'I no longer believe in Lenin' before fleeing into exile.

Theorist of the mass workers' party: the argument that lost to Lenin's vanguard

Trotsky recalled: 'An atmosphere of simplicity and sincere comradely participation reigned in the Akselrod household.'

A former narodnik, he co-founded the Emancipation of Labour group (1883) with Plekhanov and Zasulich, the first Russian Marxist organisation. As an Iskra editor (1900) and, after the 1903 RSDLP split, the central theoretician of Menshevism, he argued for a mass, democratic workers' party against Lenin's vanguard model. He served on the Petrograd Soviet executive in 1917 but opposed the October Revolution and spent his final decade in exile, active in the Second International.

Founder of Marxist revisionism and evolutionary socialism, author of The Preconditions of Socialism

"I have extraordinarily little interest in what is called the 'final goal of Socialism.' This aim, whatever it be, is nothing to me, the movement everything." — Response to critics (1899)

German SPD theorist and politician. Engels's literary executor and editor of Der Sozialdemokrat, Bernstein began as an orthodox Marxist before his 1899 The Preconditions of Socialism challenged Marx's predictions of capitalist collapse, class polarization, and revolutionary necessity. His dictum "the goal is nothing, the movement everything" laid the foundation for social democracy's reformist, parliamentary turn, creating the schism between revolutionary socialism and evolutionary social democracy. He broke with the SPD's pro-war majority to co-found the anti-war USPD during World War I, and spent his final years defending Weimar parliamentary democracy, dying six weeks before Hitler took power.

At the Brussels Bureau meeting of July 1914 he confessed that “the war is already with us” and that his party was powerless, and despite private misgivings backed the government’s war. He became foreign minister of the provisional government in October 1918 but died on 11 November, a day before the republic was proclaimed.

A former Narodnik and member of Black Repartition, in 1883 he co-founded the Emancipation of Labour group in Switzerland with Georgi Plekhanov and Vera Zasulich, Russia's first Marxist organization. As the group's chief organizer, he ran its clandestine printing and smuggling network until his arrest in Germany in 1884 and extradition to Russia, where he served thirteen years of katorga at Kara. After a dramatic escape in 1901, he joined the editorial board of Iskra and at the RSDLP's Second Congress aligned with the Mensheviks, helping shape the party's formative split; his memoir Half a Century (За полвека) remains a primary source on the Russian revolutionary movement.

The father of Russian Marxism: against his own pupils’ revolution

After the October 1917 seizure of power, Plekhanov said: "Russian history has not yet ground the flour from which the wheat pie of socialism will be baked."

He began as a Populist and transplanted Marxism into Russia: Lenin’s whole generation learned from his books. But returning in 1917 after thirty-seven years abroad, he condemned the October rising as premature, a violation of history’s stages. He died of tuberculosis under the regime his pupils had built, and his funeral became a half-opposition demonstration.

French Section of the Workers' International (SFIO) Non-Bolshevik socialists 1859–1914 ✕ Assassinated

French socialist leader who united the left, founded L'Humanité, and was assassinated fighting to prevent the Great War

"In the vat of the Republic, prepare the wine of the Social Revolution!" — to winegrowers at the Maraussan cooperative, 1 May 1905

Jean Jaurès was the central figure in the unification of French socialism, leading the French Socialist Party from 1902 and merging it with Jules Guesde's revolutionary Socialist Party of France in 1905 to create the French Section of the Workers' International (SFIO). Through L'Humanité, the daily he founded in 1904, he championed reformist social democracy, while during the Dreyfus Affair he stood as the republican conscience against anti-Semitism and militarism. His Marxist class analysis in the multi-volume Socialist History of the French Revolution (1900–1903) left a lasting mark on French revolutionary historiography. In July 1914, he fought to prevent world war through an international general strike with the German Social Democrats, but was assassinated by nationalist Raoul Villain three days before France entered the conflict.
