Context: The Spartacist uprising mobilized hundreds of thousands of revolutionary workers, soldiers, and sailors who took to Berlin’s streets in January 1919, with armed groups occupying newspaper buildings and strategic sites. Despite the name, the revolt was largely spontaneous. The Spartacus League and Communist Party leadership had limited control over the masses, with Rosa Luxemburg actively opposing the premature action.

The insurgent forces lacked military organization and coordination, with many participants seeking unity among socialist factions rather than armed confrontation. They faced overwhelming firepower from government-deployed Freikorps militias—right-wing paramilitary units of former frontline soldiers who used flamethrowers, artillery, and machine guns to brutally crush the poorly-armed workers.
