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.

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.

French Socialist deputy who joined the Union sacrée government as Minister of Public Works in 1914

Born in Bonnières-sur-Seine in Seine-et-Oise, he took a doctorate in law and practised as a lawyer, and as a journalist edited La Petite République. He joined the Blanquist-leaning Central Revolutionary Committee and followed its successor parties into the SFIO in 1905. From 1893 until his death he was re-elected as a Socialist deputy for a working-class district in the 18th arrondissement of Paris. Author of the 1911 pacifist pamphlet Faites un roi, sinon faites la paix, he nevertheless entered Viviani’s Union sacrée government in August 1914 as Minister of Public Works, and kept the post under Briand until December 1916. At the Congress of Tours in 1920 he voted against joining the Third International. He died of a cerebral haemorrhage in Chamonix in 1922.

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.

SFIO general secretary who led the Tours vote to join the Comintern, became the first PCF general secretary and left in 1923

At the 1920 Tours Congress, Frossard led the move to join the Comintern and became the French Communist Party’s first general secretary, but left in 1923. Later a minister, he joined Pétain’s cabinet in 1940, voted for his full powers, and was acquitted of collaboration after the war.

A teacher from the Belfort region, he joined the SFIO and became its general secretary in 1918. After visiting Moscow with Cachin in 1920 he backed joining the Comintern at the Tours congress and became the first general secretary of the new French Communist Party. Clashing with the Comintern’s demands for discipline, he left in January 1923 and returned to the SFIO. He served as a minister in several governments in the 1930s and joined Pétain’s first cabinet in June–July 1940, but declined to serve Vichy; after the war he was tried for collaboration and acquitted.

The Socialist left's tribune who wrote 'Everything is possible', the Popular Front's left frontier

'Everything is possible', the title and the conclusion of his front-page article in Le Populaire as the strikes surged, 27 May 1936

A schoolmaster who became the leader of the Socialist SFIO's left. In 1935 he founded the Revolutionary Left tendency, supporting the Popular Front while arguing for a revolutionary way beyond it, and at the height of the strikes in May 1936 he planted himself at the centre of the argument with 'Everything is possible' in Le Populaire. He ran the premier's press service under Blum without ceasing to radicalize, and when the party expelled him in 1938 he founded the Workers' and Peasants' Socialist Party (PSOP). Exiled in Mexico during the war, he returned to the SFIO afterward and stood on its left and in the anticolonial camp until his death.
