"The struggle in Paris is only a small outpost skirmish; the main affair in Europe is still ahead of us. Before a few decades have passed, 'War on the palaces, peace to the cottages' will become the battle cry of the entire European proletariat." — Reichstag, 25 May 1871
A woodturner's apprentice who co-founded the Social Democratic Workers' Party with Wilhelm Liebknecht in 1869 and, through the Gotha unity congress of 1875, built the SPD into the world's largest socialist party.

The elder theoretician of German Marxism: historian, literary critic, and Spartacus League co-founder
Lenin characterized Mehring as 'a man not only wanting but also knowing how to be a Marxist.'
Franz Mehring was the foremost Marxist historian, literary critic, and philosopher of the German workers' movement. Joining the SPD in 1891, he became a lead writer for Die Neue Zeit and, alongside Kautsky and Luxemburg, formed the theoretical backbone of the party's Marxist left. He co-founded the Spartacus League in 1916, led the founding of the German Communist Party (KPD) in 1919, and authored the classical Marx biography Karl Marx: The Story of His Life (1918) and the landmark History of German Social Democracy (1898). His The Lessing Legend (1893), a materialist demolition of Prussian mythology, drew high praise from Engels, and he extended historical materialism into cultural criticism against the encroachments of neo-Kantianism and Nietzsche.

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.

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.
