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.

'Sherlock Holmes of the Revolution' who serially exposed Tsarist secret police agents provocateurs

On the night of the October Revolution, Trotsky's men knocked on his Petrograd apartment door. Burtsev had just published Nashe Obshcheye Delo that morning — the only opposition newspaper to appear in the city that day.

A revolutionary and publisher from the Narodnaya Volya tradition, he became known as the 'Sherlock Holmes of the Revolution' for serially exposing Okhrana agents provocateurs including Yevno Azef. He founded the historical journal Byloye (Былое), systematically documenting the 19th-century Russian revolutionary movement, and testified at the Berne Trial that the Protocols of the Elders of Zion was an Okhrana forgery. Arrested on Trotsky's orders on the day of the October Revolution, he became the Soviet regime's first political prisoner, and continued his anti-Bolshevik and anti-fascist struggle from exile in Paris.

From Legal Marxism to ethical socialism: the economist who pioneered business cycle theory

At the April 1900 Pskov meeting to organize Iskra, he sat alongside Lenin, Martov, and Struve — but he never actually joined the underground Social Democratic movement.

A leading exponent of Legal Marxism, Tugan-Baranovsky gained international recognition with his 1894 Industrial Crises in Contemporary England, which pioneered an endogenous theory of capitalist business cycles. Together with Pyotr Struve he advanced Marxist economic-historical analysis against the Narodniks and attended the 1900 organizational meeting of Iskra, but later broke with orthodox Marxism toward an 'ethical socialism' grounded in Kantian ethics, laying the theoretical foundations of the cooperative movement. After the February Revolution he served as finance minister in the Ukrainian Central Rada and was a founding member of the Ukrainian Academy of Sciences; his cycle theory influenced Keynes, Robertson, and Kalecki.

Architect of Soviet Marxist legal theory who defined law as class relations

'Law is a system, an order of social relations which corresponds to the interests of the ruling class and is maintained by the organized power of this class, the state.' (The Revolutionary Role of Law and the State)

Latvian jurist and revolutionary. Born 14 (26) July 1865 in Koknese volost, Riga district, Livonia province, he died in Moscow on 25 January 1932 and his ashes were placed in an urn in the Kremlin wall. With Rainis he led the Latvian Marxist 'New Current' and the newspaper Dienas Lapa, was arrested in 1897 and after seven months' imprisonment exiled for five years to Vyatka province. As People's Commissar of Justice after October he co-authored Decree on Courts No. 1, laying the foundation of Soviet justice, headed the Latvian Soviet government (1918–1920) and served as first chairman of the RSFSR Supreme Court from 1923 until his death.

Creator of the Japhetic theory who, as the sole Imperial academician to join the Communist Party, dominated Soviet linguistics for decades

'The formulation of the study of language on a worldwide scale' — that was Marr's favourite phrase for his own theory. To him, all languages descended from four primordial elements, and language itself was a class superstructure.

Born in Kutaisi, Georgia to a Scottish father and Georgian mother, Marr made his name in Caucasian linguistics and archaeology at St. Petersburg University, becoming a full member of the Imperial Academy of Sciences in 1912 and conducting landmark excavations at the ancient Armenian capital of Ani. After the Revolution, he propounded the 'Japhetic theory,' the New Doctrine of Language, which treated language as a class-bound superstructure and traced all words to four primordial elements (sal, ber, yon, rosh); joining the Party in 1930 as the Academy's only Imperial-era member to do so, he became vice-president and dominated Soviet linguistics until 1934. His pseudo-scientific doctrine was officially repudiated by Stalin's 'Marxism and Problems of Linguistics' in 1950, yet his career epitomizes the collision of science, ideology, and state power in the early Soviet period.

Historian who wrote Ukraine as a distinct historical subject, and chairman of the Central Rada

In March 1917 the Central Rada elected him chairman in absentia while he was still in exile in Moscow, and his return raised hope for uniting the democratic forces.

The historian whose History of Ukraine-Rus wrote Ukraine as a distinct historical subject, he chaired the Central Rada in 1917 and 1918. He returned to Soviet Ukraine in 1924 and died under surveillance in 1934.

Co-author of permanent revolution who arranged Lenin's sealed train: the 'merchant of revolution'

In December 1917, Lenin refused Parvus's request to return to Russia with the words: 'the cause of the revolution should not be touched by dirty hands.'

A Marxist theorist and journalist in the German SPD who co-developed the theory of permanent revolution with Leon Trotsky in 1904–1905. During World War I, he built a revolutionary network inside Russia with German government funding and played the decisive role in arranging Lenin's return via the 'sealed train' in April 1917. After the Bolsheviks took power, Lenin refused his request to return, declaring that 'the cause of the revolution should not be touched by dirty hands'; Parvus remained in Germany and became an advisor to early Weimar Republic leaders. Criticized for commodifying his principles between revolutionary Marxism and realpolitik, he remains one of the most controversial figures of 20th-century socialism.

An entomologist who carried scientific expertise into international relief

“Can we stop with feeding children alone while their natural protectors are allowed to die?”

Vernon Kellogg was an entomologist and science administrator whose work at Stanford advanced zoology and the institutionalization of scientific research in the United States. His wartime service with Herbert Hoover's relief work in Belgium brought him into postwar international humanitarian operations. After inspecting the Volga famine zone in 1921, he reported to Washington that relief could not be limited to children while their parents and other adults died, helping support the American Relief Administration's expansion. His career shows a scientific specialist becoming an agent of administrative and ethical judgment in the face of mass starvation.

The Bolshevik elder removed by Stalin for trying to Sovietize Georgia gently

"The establishment of Soviet power in Georgia had the outward appearance of a foreign occupation, because in the country itself there was nobody ready to take part in a rebellion": report to the Central Committee, December 1921

Born in Guria to a priest's family, Makharadze studied at Tbilisi Theological Seminary and the Warsaw Veterinary Institute before joining the Social Democratic movement in 1891. He became one of the few Bolshevik leaders in Menshevik-dominated Georgia, and as chairman of the Georgian Revolutionary Committee in February 1921 proclaimed the Soviet republic, only to be removed by Stalin in July for his moderate treatment of the Menshevik opposition and insistence on Georgian sovereignty, replaced by Mdivani. This ousting was the direct prelude to the 1922 Georgian Affair; Makharadze later held the chairmanships of Gosplan, Sovnarkom, and the Supreme Soviet Presidium in Georgia, and was one of the few Old Bolsheviks to survive the Great Purge, dying a natural death in 1941.

"Capitalism cannot reform itself": father of the modern Negro liberation movement who joined the Communist Party at 93

"Communism will triumph. I want to help bring that day." — from his 1961 application to join the Communist Party USA, submitted at age 93

American sociologist, historian, Pan-Africanist, and the single most important African American intellectual of the 20th century. A co-founder of the NAACP, he edited its magazine The Crisis for 24 years, shaping the direction of the black civil rights movement, while his books The Souls of Black Folk and Black Reconstruction in America transformed American sociology and historiography. He viewed capitalism as the root cause of racism and pursued a synthesis of Marxism and Pan-Africanism. In 1961, at age 93, he joined the Communist Party USA; invited by Kwame Nkrumah, he settled in Ghana to begin work on the Encyclopedia Africana, and died there in 1963.

Russian cultural historian who launched the Vekhi collection and urged the intelligentsia toward spiritual self-awareness

In his introduction to Vekhi (1909), Gershenzon wrote: "We must bless this government which alone, with its bayonets and prisons, still protects us from the fury of the people."

A Russian cultural historian and essayist, Mikhail Gershenzon was the initiator and editor of the landmark 1909 collection Vekhi (Landmarks), which denounced the revolutionary radicalism of the Russian intelligentsia. He argued that the intelligentsia, fixated on reorganizing external social forms, had neglected the inner life of the spirit: a stance crystallized in his provocative line that "we must bless this government which alone, with its bayonets and prisons, still protects us from the fury of the people." After the revolution, he served as the first chair of the All-Russian Writers' Union and headed the literary section of Narkompros, while his scholarship on Pushkin (The Wisdom of Pushkin, 1919) and 19th-century Russian thought left a lasting intellectual legacy.

A historian who linked scholarship with social democracy

In Moscow in 1940, he signed the peace treaty that ended the Winter War.

Väinö Voionmaa was a Finnish historian, professor and Social Democratic politician who helped shape the early republic. He founded institutions for workers’ education and joined scholarship to popular political work through parliament, diplomacy and social policy. As a Social Democratic member of Finland’s delegation to the Moscow Peace Treaty negotiations in 1940, he signed the settlement that ended the Winter War, embodying the difficult compromises imposed on Finland between war and great-power politics.

A publicist who moved between reformist socialism and anti-party politics

During the famine of 1921 she worked in Pomgol relief, and the following year she was expelled from Soviet Russia.

Yekaterina Kuskova was a political activist and writer who moved from revolutionary populism through Marxism and Economism toward liberal reformist socialism. Her 1899 Credo, which prioritised workers’ economic struggle and democratic reform, helped provoke a major dispute over the strategy of Russian Social Democracy. After 1905 she pursued democratic alliances through the Union of Liberation, the cooperative movement, women’s equality work, and journalism; in 1917 she supported the Provisional Government while also opposing the Kornilov movement. During the famine of 1921 she organised non-Bolshevik relief work in Pomgol with Sergei Prokopovich, but after the committee was dissolved she was arrested and expelled, continuing to write in exile.

Founder of the Marx-Engels Institute and independent Marxist who never stopped disagreeing

«Stop it, Koba, don't make a fool of yourself. Everybody knows theory is not exactly your field.» — to Stalin at a party meeting.

A Jewish-Russian Marxist from Odessa who joined the revolutionary movement at 17. In 1921 he founded the Marx-Engels Institute (IME), assembling the world's finest collection of Marxist documents and personally recovering, editing and first publishing Marx and Engels' unpublished manuscripts, including the first chapter of The German Ideology and Dialectics of Nature. A full member of the USSR Academy of Sciences (1929) and the foremost Marx scholar of his generation, his independence (public opposition to the dissolution of the Constituent Assembly, the Brest peace, and the suppression of dissent within the party) led to his arrest in 1931 and execution in Saratov in 1938.

First Procurator General of the USSR and architect of revolutionary legality

At the 1922 Petrograd trial, Krasikov demanded the death penalty for Metropolitan Veniamin, arguing that "the church must kneel before the revolution" — and the court obliged.

A Bolshevik revolutionary who joined Plekhanov's Emancipation of Labour group in Geneva in 1892 and sat on the Bureau of the II RSDLP Congress in 1903 alongside Lenin and Plekhanov, he became the USSR's first Procurator General in 1924 and laid the institutional foundations of the Soviet judicial system. He founded the anti-religious journal Revolution and Church, helped draft the Soviet constitutions of 1918, 1924, and 1936, and died of illness in 1939 after being removed during the Great Purge.

From Marxism through liberalism to conservative anti-Bolshevism: the thinker who traced the arc of a Russian intelligentsia

Vasily Shulgin recalled asking him: “So you too should have been crushed?” Struve, trembling his white beard, rose and shouted: “Yes! Me first! The moment a revolutionary raises his head — whack! — a rifle butt to the skull!”

A thinker who moved from legal Marxism through liberal activism, co-founding the Union of Liberation and contributing to Vekhi (1909), to becoming a White ideologue. He wrote the first RSDLP Manifesto (1898) and sustained anti-Bolshevik scholarship in emigration.

Russian revolutionary who organized the first Marxist circles in the Volga region

"Fedoseev enjoyed the extraordinary sympathy of all who knew him, as the model of an old-time revolutionary, wholly devoted to his cause" — Lenin, 1922

Nikolai Fedoseev was a pioneer of Russian Marxism who organized the first Marxist study circle in Kazan in 1888, introducing young Lenin and Maxim Gorky to Marxist theory. From prison, he corresponded with Lenin on questions of Marxist worldview, and wrote a major study analyzing the economic causes of the fall of serfdom in Russia, as well as a draft program for a proletarian party. His polemic against the Narodnik theorist Nikolai Mikhailovsky opened the early Marxist-Narodnik debate, and Lenin later called his party program draft 'the only correct one'. But in 1898, hounded by a fellow exile's slander in Siberia, he took his own life at 27.

The Marxist economist who became a priest and built the theological system of Sophia

At the funeral of his four-year-old son Ivan in 1909, Bulgakov recorded: 'I understood what "God spoke" means' — a mystical experience he regarded as the final step in his return to Orthodoxy.

A Russian Orthodox theologian and economist whose trajectory from legal Marxist to ordained priest traced the defining intellectual pilgrimage of 20th-century Russia. Gaining recognition in the 1890s for Marxist economic writings, he discovered the limits of Marx's theory in his two-volume Capitalism and Agriculture (1900) and, passing through Kant and Vladimir Solovyov's philosophy, returned to the Orthodox Church. His landmark Vekhi essay 'Heroism and Asceticism' (1909) indicted the intelligentsia's atheistic revolutionism; exiled on the 'Philosophers' Ship' in 1922, he co-founded the St. Sergius Orthodox Theological Institute in Paris and completed his sophiological theological system.

Menshevism's theoretical pillar who stood for democratic socialism against Lenin

In 1943, the lifelong anti-Bolshevik Menshevik leader Dan wrote in The Origins of Bolshevism that Bolshevism had been chosen by history to be 'the carrier of socialism, the key idea of our epoch.'

Fyodor Dan was a revolutionary, physician, and a founding leader and chief theorist of the Menshevik faction of the RSDLP. At the 1903 Second Congress he sided with Martov against Lenin; after the February Revolution he became the leading ideologist of 'revolutionary defencism' and served on the Executive Committee of the Petrograd Soviet and the Presidium of the Central Executive Committee. Exiled in 1922, he headed the Menshevik Foreign Delegation from Martov's death in 1923 until 1940, upholding democratic socialism against both Bolshevik authoritarianism and Western social-democratic accommodation. In The Origins of Bolshevism (1943) he recognized Bolshevism as the historical carrier of socialism while arguing for political liberalization in the Soviet Union.

An economist who analysed the tension between markets and state control

“Retailers speculated earlier and they are speculating now, although there were no high prices earlier but now there are.”

Sergei Prokopovich was an economist who studied Russia’s agrarian, labour and cooperative problems through statistics and political economy. He moved from revolutionary Marxism toward revisionist social democracy and liberal politics, while continuing to argue that the state should regulate markets and address workers’ and peasants’ living conditions. As Minister of Food Supply in the Provisional Government in 1917, he confronted a crisis in which wartime mobilisation, transport disruption and peasant retention of grain undermined fixed prices and the state grain monopoly. After helping organise famine relief, he was arrested and expelled, then analysed the Soviet economy statistically in exile.

First Soviet editor of Izvestia, architect of the Soviet constitution

His Izvestia editorials were nicknamed steklyashki ("little Steklovs"), and Lenin sent him a handwritten note: "Comrade Steklov! I've read your editorial. This is how one should write, and more of it!" Steklov framed the note and hung it on his office wall.

Bolshevik journalist and historian from Odessa. After the February Revolution he became editor of the Petrograd Soviet's Izvestia and held the post until 1925. He co-drafted the 1918 RSFSR and 1924 USSR constitutions and served on the VTsIK Presidium. With Gorky he co-edited Novaya Zhizn and initiated the monthly Novy Mir. He left a vast body of work on socialist thought including major biographies of Bakunin and Chernyshevsky. Arrested in 1938, he died in Saratov prison in 1941 and was rehabilitated in 1956.

A Russian thinker who left Marxism to found a Christian existentialist philosophy of freedom

Arrested in 1922, Berdyaev was interrogated at midnight by Cheka chief Felix Dzerzhinsky — and instead of begging, gave him a thorough dressing-down on the problems of Bolshevism. Dzerzhinsky freed him. As Solzhenitsyn wrote: "Now there is a man who had a 'point of view'!"

A Russian religious and political philosopher who moved from Marxism to Christian existentialism and personalism, becoming one of the most influential Russian thinkers of the 20th century. A leading contributor to Vekhi (1909), he critiqued revolutionary radicalism and, after the Bolshevik takeover, founded the Free Academy of Spiritual Culture to sustain independent philosophical work under Soviet rule. Expelled in 1922 on the 'Philosophers' Ship,' he wrote major works in Berlin and Paris — including The Russian Idea and Slavery and Freedom — and was nominated seven times for the Nobel Prize in Literature. His concept of 'uncreated freedom' — a freedom not even God controls — profoundly shaped existentialist political theology and critiques of totalitarianism worldwide.
