Rosa Luxemburg was a prominent Marxist theorist and revolutionary socialist known for her critiques of capitalism and imperialism. Born in Poland in 1871, she moved to Germany, where she became actively involved in socialist politics. Luxemburg was a key figure in the German Social Democratic Party (SPD) and later co-founded the revolutionary socialist group known as the Spartacus League. Her writings emphasized the importance of revolutionary action and the need for a working-class movement to achieve socialism. Luxemburg’s most significant contributions include her theories on imperialism, the mass strike, and her critique of Leninism. She argued that capitalism's expansion leads to imperial conflicts and that genuine revolutionary change should come from the working class's grassroots movements rather than top-down leadership. Her notable works, such as "The Accumulation of Capital" and "The Mass Strike," continue to influence leftist thought and debates over the nature of revolution. Tragically, Luxemburg’s life was cut short in 1919 when she was murdered during the German Revolution. Her legacy endures as a symbol of radical thought and activism. Luxemburg's ideas challenge conventional Marxist strategies and advocate for a more democratic and participatory approach to socialism, making her a vital figure in the history of socialist movements.
