People like Rosa Luxemburg

Rosa Luxemburg (Polish: [ˈruʐa ˈluksɛmburk] (listen); German: [ˈʁoːza ˈlʊksəmbʊʁk] (listen); Polish: Róża Luksemburg or Rozalia Luksenburg; 5 March 1871 – 15 January 1919) was a Polish and naturalised-German revolutionary socialist, Marxist philosopher and anti-war activist. Successively, she was a member of the Proletariat party, the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD), the Spartacus League (Spartakusbund), and the Communist Party of Germany (KPD). Born and raised in an assimilated Jewish family in Poland, she became a German citizen in 1897.

After the SPD supported German involvement in World War I in 1915, Luxemburg and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund) which eventually became the KPD. During the November Revolution, she co-founded the newspaper Die Rote Fahne (The Red Flag), the central organ of the Spartacist movement. Luxemburg considered the Spartacist uprising of January 1919 a blunder, but supported the attempted overthrow of the government and rejected any attempt at a negotiated solution. Friedrich Ebert's majority SPD government crushed the revolt and the Spartakusbund by sending in the Freikorps, government-sponsored paramilitary groups consisting mostly of World War I veterans. Freikorps troops captured and assassinated Luxemburg and Liebknecht during the rebellion.
