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.

Founder of Marxist revisionism and evolutionary socialism, author of The Preconditions of Socialism

"I have extraordinarily little interest in what is called the 'final goal of Socialism.' This aim, whatever it be, is nothing to me, the movement everything." — Response to critics (1899)

German SPD theorist and politician. Engels's literary executor and editor of Der Sozialdemokrat, Bernstein began as an orthodox Marxist before his 1899 The Preconditions of Socialism challenged Marx's predictions of capitalist collapse, class polarization, and revolutionary necessity. His dictum "the goal is nothing, the movement everything" laid the foundation for social democracy's reformist, parliamentary turn, creating the schism between revolutionary socialism and evolutionary social democracy. He broke with the SPD's pro-war majority to co-found the anti-war USPD during World War I, and spent his final years defending Weimar parliamentary democracy, dying six weeks before Hitler took power.
