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.

The 'Tiger of the Revolution' who founded the SR Combat Organization

Arrested in Kiev in May 1903, Gershuni did not resist — instead he kissed his handcuffs and leg irons before the watching gendarmes, a gesture that entered revolutionary legend.

A co-founder of the Socialist Revolutionary Party and the founder and first leader of its Combat Organization, he masterminded the political assassinations that shook the Russian Empire in 1902–1903, beginning with Interior Minister Sipyagin. Born to a Jewish family, he was a pharmacist and bacteriologist who ran cultural-enlightenment schools in Minsk before the limits of legal methods drove him to become a full-time revolutionary; as the 'Tiger of the Revolution' he became the Empire's most wanted man. Arrested in 1903 and sentenced to death, commuted to life at hard labor, he escaped the Akatuy katorga in 1906 hidden in a barrel of sauerkraut, traveling through China, Japan, and the United States to return to Europe, where he died before learning that his deputy and successor Yevno Azef was an Okhrana spy.

Founder and chief theoretician of the Socialist Revolutionary Party

18 January 1918, Tauride Palace. Elected Chairman, Chernov opened Russia's first — and last — democratically elected parliament. After Bolshevik deputies walked out, the Assembly passed the land socialization law. At 4:40 a.m., the armed guard approached: 'The guard is tired. Please close the session.' Chernov scheduled the next meeting and gavelled the session closed. It never reconvened.

He fused narodnik agrarianism with Marxism to make land socialization the PSR's core program, serving as its chief theoretician. Elected chairman of the Constituent Assembly in 1917; after the Bolsheviks dissolved it, he spent 32 years in exile answering with his pen.

SR Party founder who chaired the last unified anti-Bolshevik government, overthrown by Kolchak

Trotsky called him 'the complete caricature of a statesman. A really charming teacher of language in a ladies' seminary in Oryol — that is really all you can say about him.'

A founder and right-wing leader of the Socialist Revolutionary Party, he led the SR faction in the 1905 St. Petersburg Soviet and served as Minister of the Interior and chairman of the Pre-Parliament in Kerensky's Provisional Government. During the Civil War, as the culmination of efforts to unite the anti-Bolshevik camp, he was elected chairman of the Provisional All-Russian Government (Ufa Directory) at the Ufa State Conference. Arrested and expelled by Kolchak's coup in November 1918, he continued émigré journalistic work in Paris and New York. His political trajectory encapsulates the collapse of democratic socialism in the Russian Revolution, crushed between armed extremes.

Terrorist, Counter-Revolutionary: the Black Horse of the Revolution

At his 1924 trial: 'I am Savinkov, of the Plehve and Grand Duke Sergei assassinations. All my life I worked for the people, yet now I am charged with bearing arms against the workers' and peasants' power.'

Revolutionary and novelist who led the SR Combat Organization, directing assassinations of high-ranking tsarist officials. His The Pale Horse (1909) novelized the psychology of terrorism.

A Socialist Revolutionary who defended democratic socialism through exile and testimony

Arriving at his place of exile, Russkoye Ustye, Zenzinov wrote in his diary: 'This is, of course, Russia, but Russia of the 17th, perhaps 16th century.'

Vladimir Zenzinov was a member of the Socialist-Revolutionary Party's Central Committee and a journalist who turned three Siberian exiles into pioneering ethnographic and ornithological study of the Arctic. In 1918 he backed the democratic alternative of the Samara Constituent Assembly committee and the Ufa Directory between Bolshevik power and Kolchak's military rule, before the Omsk coup banished him, and he spent his last decades recording the revolution and civil war in Paris and New York.

The orator ground away between revolution and counter-revolution

In March 1917, taking the rostrum of the Petrograd Soviet to announce his acceptance of the Justice Ministry, he cried: "I cannot live without the people. In the moment you begin to doubt me, then kill me!" The workers and soldiers filling the hall erupted in wild applause.

The face of the Provisional Government and its last premier. In August 1917 he armed even the jailed Bolsheviks to stop Kornilov; in October, no army anywhere would come to save him. The story of his escaping in a dress is a Soviet fabrication. He spent half a century in exile lecturing on what had gone wrong, and died in New York.

Bessarabian Socialist Revolutionary who headed the first government of the Moldavian Democratic Republic and put land reform first

Born in Tănătari, Bessarabia, in 1884, he graduated from the Chișinău seminary and the Faculty of Letters in Saint Petersburg and taught.

In December 1917 he became President of the Council of Directors General, the Moldavian Democratic Republic’s first government, and Director General for Agriculture, putting land reform first. His view that the republic should bear the majority people’s name prevailed; he put the entry of Romanian troops to a vote, yet protested their presence, fearing they would be used to block land reform. He voted for union but resigned amid charges of a pro-Russian stance, and later sat in the Romanian Senate. He fled to Bucharest in 1940 and died there in 1971.
