Lore & Background

Rosa Luxemburg was born Rozalia Luksenburg on 5 March 1871 in Zamość, a town in Russian-controlled Congress Poland, the fifth and youngest child of a secular Jewish family. At age five, she developed a hip disease—probably a congenital hip dislocation—misdiagnosed as tuberculosis, leading to a year in a cast and a permanent limp. In 1880 she enrolled at the Second Girls' High School in Warsaw, where a quota on Jewish students intensified her sense of being an outsider. After the 1881 Warsaw pogrom, she found refuge in the poetry of Adam Mickiewicz. While still in her teens, she joined clandestine student circles linked to the revolutionary Proletariat party. By 1889, threatened with arrest, she was smuggled out of Poland—according to one account, hidden under straw in a peasant's cart and taken across the border by a Catholic priest. In Zurich in 1893, she co-founded the Social Democracy of the Kingdom of Poland (SDKP), a party that rejected Polish nationalism in favor of international class struggle. At the Second International's third congress in 1893, her mandate was challenged by the Polish Socialist Party (PPS); small and frail, she climbed onto a chair to defend her cause, achieving a moral victory. After moving to Germany in 1898, she became the foremost voice of the SPD's revolutionary wing. In her 1900 pamphlet *Social Reform or Revolution?*, she defended the necessity of revolution against Eduard Bernstein's reformist theories, arguing that reforms were a means to an end, not an end in itself.

Reader's Guide

Luxemburg's significance lies in her theoretical contributions and her role as a revolutionary leader. Inspired by the 1905 Russian Revolution, she developed a theory of the mass strike as the proletariat's most important revolutionary tool, emphasizing the spontaneous creativity of the working class. Her major work, *The Accumulation of Capital* (1913), argued that capitalism's need to expand into non-capitalist regions to survive was the driving force behind imperialism. As World War I approached, her anti-militarist and anti-imperialist convictions brought her into conflict with the SPD leadership; she fiercely condemned the party's support for the war and was imprisoned for most of the conflict. From prison, she wrote the *Junius Pamphlet*, which declared the war a betrayal of the working class and popularized the phrase 'socialism or barbarism' to describe the choice facing humanity. She celebrated the Russian Revolution of 1917, but in a posthumously published manuscript she offered a sharp critique of the Bolsheviks' authoritarian policies, defending democratic freedoms and the need for a revolution rooted in mass participation. Released from prison during the German Revolution of 1918–1919, she co-founded the KPD and became a central figure in the January 1919 Spartacist uprising in Berlin. After the uprising was crushed by the Freikorps, a government-sponsored paramilitary group, Luxemburg and her comrade Karl Liebknecht were captured and murdered on 15 January 1919. Following her death, she became a heroine and martyr for Marxists. Her legacy has been a subject of intense debate: her emphasis on spontaneity and democracy is celebrated by many on the left—particularly by the New Left and those in the libertarian socialist tradition—but sharply criticized by the Stalinist tradition, which denounced 'Luxemburgism' as a heresy.
