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.

As the KPD’s delegate to the Comintern’s founding congress in March 1919 he abstained on the founding vote, as Luxemburg and Jogiches had advised, believing a premature International would be dominated by the Bolsheviks.

Marxist playwright who weaponized theatre for class struggle through epic theatre and the Verfremdungseffekt
When I read Marx's Capital, I understood my plays — Marx was the only spectator for my plays I'd ever come across.
Bertolt Brecht was the 20th century's most important Marxist playwright and the founder of epic theatre, a poet and director who transformed the stage into a forum for class consciousness and anti-capitalist critique. After embracing Marxism under Karl Korsch in the late 1920s, he developed the Verfremdungseffekt — a defamiliarization technique that broke emotional immersion to provoke critical reflection — and with works like The Threepenny Opera, Mother Courage and Her Children, and The Good Person of Szechwan, he fused avant-garde form with popular idiom to anatomize capitalism and war. Driven out by the Nazis in 1933, he lived in exile in Scandinavia and the US—where HUAC investigated him in 1947—before returning to found the Berliner Ensemble with Helene Weigel in East Berlin in 1949, defining postwar theatre worldwide until his death in 1956.
