A Pole who passed through the German and Russian revolutions and tried to bring revolution home
As the Red Army prepared to march on Warsaw in 1920, he joined Radek in repeatedly urging Lenin to halt — warning him not to overestimate the revolutionary consciousness of the Polish worker.
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. During the Polish-Soviet War of 1920 he served as chairman of the Polish Provisional Revolutionary Committee, and later became the first chairman of International Red Aid (MOPR) and first rector of the Communist University of the National Minorities of the West.

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. After Luxemburg and Liebknecht were murdered in January 1919, Jogiches took over KPD leadership and investigated their killings, only to be assassinated by the same Freikorps milieu two months later.

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.

“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.

The UGT worker-leader they called the Spanish Lenin, a prime minister broken between revolution and war
In November 1936 Largo Caballero appointed four CNT leaders to his cabinet: anarchists whose programme was the abolition of the state took ministerial office in one. One of them, the health minister Federica Montseny, was the first woman to hold a ministry in Spanish history.
A man who left school at seven, worked as a stucco plasterer and became a union leader. At the head of the UGT he was sentenced to life for the general strike of August 1917, and under the Primo de Rivera dictatorship he took a seat on the Council of State to keep the organization alive, a choice argued over for the rest of his life. As labour minister of the Second Republic he pushed through the eight-hour day in the countryside, and around the Asturias rising of 1934 he moved so far left that his supporters called him the Spanish Lenin. In September 1936 he became prime minister and war minister, and in November brought four CNT leaders into the cabinet, seating anarchists in a government for the first time; but he clashed continuously with the communists and the Soviet advisers over rebuilding a regular army and over the pace of the revolution. After the May Days of 1937 he refused to outlaw the POUM, lost his ministers and fell. In exile in France he was seized by the Gestapo and held in Sachsenhausen until the liberation of 1945.

After his release he became editor of Emma Goldman's Mother Earth and a central figure in the American anarchist movement; in 1919 he was deported to Soviet Russia for anti-war activism. Initially enthusiastic about the Bolshevik Revolution, he became disillusioned after witnessing the Kronstadt rebellion's suppression and documented the early Soviet state's authoritarianism in The Bolshevik Myth (1925); in French exile he wrote the anarcho-communist primer Now and After (1929).

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.

A lifelong organizer and theorist who dedicated himself to building Chile's labour movement and socialist party. Witnessing the brutal conditions of nitrate miners, he joined the Democratic Party but broke with its reformism in 1912 to found the Socialist Workers' Party (POS). Despite repeated imprisonment and exile, he launched and edited workers' newspapers, toured the country raising class consciousness, and in 1922 affiliated the party to the Comintern, transforming it into the Communist Party of Chile.
