Alexander Guchkov led the Union of 17 October (Octobrists), championing constitutional monarchy and Stolypin's reforms as a conservative liberal. As Chairman of the Third Duma, he denounced Rasputin and the court, becoming an enemy of Nicholas II. On 2 March 1917 he and Vasily Shulgin received the Tsar's abdication at Pskov; he became War Minister but resigned during the April Crisis. He later backed Kornilov and the White movement.

Chairman of the Petrograd Soviet in the dual-power era, face of revolutionary defencism

A Pole who passed through the German and Russian revolutions and tried to bring revolution home

Co-founder of Polish communism, he established the Social Democracy of the Kingdom of Poland (SDKPiL) in 1893 together with Rosa Luxemburg and Leo Jogiches. Active in the German SPD's left wing, he helped build the Spartacus League and the German Communist Party, and after the Russian Revolution joined the Bolsheviks, becoming one of Lenin's close advisers on agrarian policy.

Founding father of the Republic of China who framed the Three Principles of the People and the first united front

Credited with leading the 1911 revolution that toppled the Qing and founded the Republic of China. In a deathbed testament he dictated himself, he reaffirmed friendship with the Soviet Union.

Born in Guangdong and educated in Hawaii and Hong Kong, he trained as a physician. He founded the Revive China Society in 1894 and the Tongmenghui in Tokyo in 1905 to overthrow the Qing and build a republic; after the 1911 revolution he became provisional president but soon yielded to Yuan Shikai. He formulated the Three Principles of the People (nationalism, democracy, people’s livelihood) and in 1923, after a joint statement with the Soviet envoy Joffe, accepted Soviet aid and Communist members joining the Kuomintang as individuals, opening the first united front. He died of liver cancer in Beijing in 1925; both Nationalists and Communists claimed his legacy.

Political and party leadership Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL) 1867–1919 ✕ Murdered

The revolution's underground organizer, always behind the scenes, until he had to lead

On 10 March 1919, still investigating the killings of Luxemburg and Liebknecht, Jogiches was arrested and shot in the back of the head in Berlin's Moabit prison within hours. His last words to an interrogator: 'You will never find these murderers.'

Polish-Jewish Marxist revolutionary. Co-founded the SDKPiL with Rosa Luxemburg in 1893, the main forerunner of the Communist Party of Poland. During the First World War he was the key behind-the-scenes organizer of the underground Spartacus League in Germany. For decades Luxemburg's closest political comrade and personal companion, a brilliant organizer who struggled to write for himself.

Political and party leadership Action Française 1868–1952 ○ Died

The brain of Action Française, the royalist theorist who denied the republic itself in the name of integral nationalism

'It is the revenge of Dreyfus!', on hearing his life sentence in the court at Lyon, 27 January 1945

A poet and polemicist from Martigues in Provence, deaf from his youth, who led Action Française for half a century after the movement formed out of the Dreyfus affair. His 'integral nationalism' called for the restoration of the monarchy and the abolition of the parliamentary republic, and named Jews, Protestants, Freemasons and foreigners as the 'four confederate states' eating France from within. The movement survived the Vatican's condemnation of 1926, and in 1938 he was elected to the Académie Française. Through January 1934 his paper named 'the thieves' day after day, and on the morning of 6 February it called on its readers to come to the Chamber that evening. He welcomed Pétain's accession in 1940 as a 'divine surprise', backed Vichy, and denounced resisters and Jews in print throughout the occupation. In January 1945 he was sentenced to life imprisonment and national degradation for collusion with the enemy.

The Siberian “holy man” who reached the imperial bedchamber

A Siberian peasant mystic. His ability to calm the heir's haemophilia won the Empress's absolute trust, and during the war he swayed ministerial appointments. Murdered in December 1916 by aristocrats hoping to save the monarchy. The dynasty collapsed two months later.

Political and party leadership Mensheviks (RSDLP) 1869–1934 → Died

One of the six who built Iskra: the Menshevik theorist who parted with Lenin

At the 1903 party congress he sided with Martov and became a leading Menshevik theorist, arguing for a mass party against Lenin's vanguard model. During WWI he led the defensist wing of Menshevism; he rejected the October Revolution and was briefly imprisoned by the Cheka in 1919. He left the USSR in 1925 and continued writing against the Soviet regime from Berlin and Paris until his death.

Political and party leadership Conservative Party (United Kingdom) 1869–1940 ○ Natural causes

The appeasement architect whose bid to avoid war helped open the way to it

Returning from Munich in 1938, he declared the agreement to mean “peace for our time.”

Neville Chamberlain was a British Conservative politician whose career combined domestic administrative reform with finance before he became prime minister. Seeking to avoid another European war and gain time for rearmament, he pursued appeasement, but the strategy failed to restrain Nazi Germany's expansion. His government's acceptance of the Munich settlement in 1938, and its limited response to Soviet proposals for collective security, formed part of the international conditions surrounding the 1939 crisis and the Nazi-Soviet Pact. After declaring war on Germany following the invasion of Poland, he resigned in 1940 amid criticism of the Norway campaign.

Political and party leadership Socialist Revolutionary Party (PSR/SR) 1870–1908 ○ Pulmonary sarcoma

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.

The leading far-right monarchist politician of late Imperial Russia, who co-founded the Black Hundreds and the Union of the Archangel Michael. As a deputy to the 2nd, 3rd, and 4th State Dumas, he was notorious for antisemitic, anti-parliamentary speeches and physical antics on the chamber floor. In December 1916, convinced that eliminating the court's 'dark forces' would save the monarchy, he joined the Rasputin conspiracy and personally fired his pistol at the fleeing starets. After the revolution he led an underground anti-Bolshevik organization, was arrested and amnestied, and died of typhus in Novorossiysk while serving the White movement.

The helmsman who changed course at every fork

Night, 16 April 1917 (3 April O.S.), Finland Station, Petrograd. Returning from exile, Lenin spoke from an armoured car, condemning the Provisional Government and calling for a continent-wide European proletarian revolution; over the following days he set out the April Theses.

Lenin was a Russian revolutionary, politician and theorist, born Vladimir Ilyich Ulyanov in Simbirsk in the Russian Empire. He led the Bolshevik faction from the 1903 RSDLP split and directed the October Revolution of 1917. His government redistributed land, nationalised banks and large industry, withdrew from the First World War by the Treaty of Brest-Litovsk, and promoted world revolution through the Communist International. At the same time its state security services carried out the Red Terror, in which tens of thousands were killed or interned, and it defeated right- and left-wing anti-Bolshevik armies in the Civil War of 1917–1922. Facing wartime devastation, famine and popular uprisings, he proposed the New Economic Policy in 1921. He died at Gorki on 21 January 1924, and Stalin succeeded him as the pre-eminent figure in the Soviet government.

Political and party leadership Spanish Socialist Workers' Party (PSOE) 1870–1940 ○ Died in prison

PSOE right-wing leader, Speaker of the Cortes; joined Casado's coup, refused exile, and died in Franco's prison

"The great majority, the masses, they cannot leave, and I, who have always lived with the workers, will continue with them and with them I will stay. Whatever is their fate will be mine," to the socialist daily La Voz, March 1939

A Marxist revisionist who started as a philosophy professor in Madrid and succeeded Pablo Iglesias as leader of the PSOE and UGT in 1925. As Speaker of the Constituent Cortes (1931) he held to a moderate parliamentarism, and his opposition to the armed rising of October 1934 cost him his party base. During the Civil War he stayed in Madrid seeking a negotiated peace, and in March 1939 joined Colonel Casado's coup against Negrín, serving on the National Defence Council; but Franco demanded unconditional surrender. When every other council member fled, Besteiro refused, telling the socialist daily La Voz that he had always lived with the workers and would share their fate; a Francoist court martial sentenced him to life imprisonment and he died in Carmona prison.

Political and party leadership Affiliation unconfirmed 1871–1949 ○ Natural causes

An Endecja theorist who pressed for a Polish nation-state

At Riga, abandoning the demand for Minsk turned Poland’s eastern policy from a federal project toward a nation-state settlement.

Stanisław Grabski was an economist and politician who began in the socialist movement before becoming one of the leading theorists of Poland’s National Democracy, or Endecja. He tied independence and state unity closely to national homogeneity and opposed a federation that would incorporate large Ukrainian and Belarusian populations. During the Minsk and Riga negotiations in 1920, he supported abandoning the demand for Minsk, weakening Piłsudski’s eastern federal project and helping define the Riga settlement as a Polish nation-state. He later served as education minister and held senior positions in the government-in-exile and the postwar state, while distancing himself from Endecja after 1926 and revising parts of his political stance.

France's first Socialist prime minister, who left behind paid holidays and the 40-hour week

'I rarely left my desk while in power; but whenever I went out and crossed the Paris suburbs and saw the roads covered with processions of jalopies, motorcycles and tandems, with working-class couples in matching pullovers, I had the feeling that, despite everything, I had brought a kind of clearing, a break in the clouds, into difficult and obscure lives', statement at the Riom trial, March 1942

A literary critic drawn into politics by the Dreyfus affair, he kept the Socialist SFIO's 'old house' standing at the 1920 Congress of Tours when the majority left to found the Communist Party. As prime minister of the 1936 Popular Front government he brokered the Matignon Agreements and enacted two weeks of paid holidays and the 40-hour week, becoming France's first Socialist and first Jewish head of government and a target of the far right. One of the eighty parliamentarians who voted against full powers for Pétain in 1940, he turned Vichy's Riom trial into a platform for defending the Popular Front, survived internment near Buchenwald, and briefly headed a caretaker government in late 1946.

Political and party leadership Mensheviks (RSDLP) 1873–1923 → Died

Lenin’s oldest friend and most principled adversary

He built Iskra alongside Lenin, then split with him in 1903 over a single clause on party membership and led the Mensheviks. After October he stayed, fighting to keep a legal opposition alive, and in 1920 was permitted to leave. He died of tuberculosis in Berlin. It is told that the dying Lenin asked after him.

Political and party leadership Soviet Communist Party and Bolsheviks 1873–1928

The man who made Lenin furious over philosophy, then died swapping his own blood: a forerunner of cybernetics

Every organisation, on achieving decisive influence in society, inevitably — regardless of how democratic its programme — tries to impose its own internal structure on the whole social order. Every collective recreates the social environment in its own image and likeness.

Bolshevik co-founder and Lenin's early philosophical rival. His 'Tektology,' a universal organizational science, made him a forerunner of systems theory and cybernetics. Founder of the world's first blood transfusion institute, he died in 1928 during an exchange transfusion self-experiment.

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.

Political and party leadership Affiliation unconfirmed 1873–1953 ○ Died in prison

Leader of the National Peasant Party who led Transylvania's union with Romania, sentenced to life in 1947 and dead in Sighet prison

On 11 November 1947 the Bucharest military court sentenced the seventy-four-year-old Maniu to hard labour for life. His closing statement came to a single sentence: everything he had done had been for the Romanian people, and history would judge.

A lawyer born into a Greek Catholic family in Sălaj, Transylvania, he began in politics as a Romanian National Party deputy in the Hungarian parliament. After the great assembly at Alba Iulia in December 1918 he led Transylvania's union with Romania as president of its Directing Council, and in 1926 he merged with the Peasant Party to found the National Peasant Party, serving as prime minister in 1928–30 and 1932–33. He opposed Carol II's personal rule and the royal dictatorship of 1938; under Antonescu he supported the recovery of Bessarabia but opposed the war beyond the Dniester, and took part in preparing the coup of 23 August 1944. After the war he was the centre of the opposition to the Groza government and Soviet domination and protested the rigging of the 1946 election. In July 1947 the arrest of party leaders attempting to fly abroad from Tămădău airfield became the pretext for dissolving the National Peasant Party, and at the trial of October and November he was sentenced to life imprisonment for "treason". He died at eighty in Sighet prison in February 1953 and was buried in an unmarked grave.

The woman Bolshevik closest to Lenin: death saved her from the Purge

In 1914 Lenin sent her alone as the Bolshevik representative to the Brussels International Socialist Bureau conference. He wrote: "I am convinced that you are one of those who develops, grows stronger, becomes more energetic and bolder when alone in a responsible post."

A French-born Bolshevik revolutionary and one of Lenin's closest comrades. As the first head of the Zhenotdel (the party's Women's Department) in 1919, she built the framework for Soviet women's emancipation policy and presided over the First International Conference of Communist Women in 1920.

Political and party leadership Soviet Communist Party and Bolsheviks 1876–1918 ✕ Executed

Bolshevik Central Committee member and Duma leader who was the Okhrana's best-paid spy

At a Bolshevik fundraising ball in February 1913, Stalin — wearing a suit and silk cravat lent by Malinovsky — was arrested while Malinovsky was talking to him; Malinovsky shouted he would free him.

A Polish-born labour organiser who rose to the Bolshevik Central Committee and leadership of the party's Duma faction (1912), Malinovsky was simultaneously the Okhrana's highest-paid secret agent, codenamed 'Portnoi' (the Tailor). Having won Lenin's deep trust, he penetrated the party leadership and enabled the arrests of Ordzhonikidze, Sverdlov, and Stalin, while deepening the Bolshevik-Menshevik split on police instructions. Forced to resign in 1914, he returned to Soviet Russia in 1918, was convicted by the Supreme Tribunal, and executed by firing squad in the Kremlin. His exposure deepened the culture of conspiratorial mistrust within the Bolsheviks, contributing to the paranoid logic that later fuelled the Great Terror.
