150 years ago today, Rosa Luxemburg was born in Zamosc, Poland. As a writer, editor, economist, philosopher, and organizer, Luxemburg was an important force in the early Communist movements in Germany.
While still a schoolgirl in Poland in the 1880s, she organized a general strike and was a member of the Proletarian Party. After fleeing to Switzerland to escape arrest, she studied at the University of Zurich where she was awarded a Doctorate of Law. After moving to Germany she co-founded the anti-war Spartacus League.
She opposed both Leninism and moderate social democracy, and was murdered by the proto-fascists after the Spartacist uprising of 1919.
