Die Rote Fahne (German: [diː ˈʁoːtə ˈfaːnə], The Red Flag) was a German newspaper originally founded in 1876 by Socialist Worker's Party leader Wilhelm Hasselmann, and which has been since published on and off, at times underground, by German Socialists and Communists. Karl Liebknecht and Rosa Luxemburg famously published it in 1918 as organ of the Spartacus League.
Following the deaths of Liebknecht and Luxemburg during the chancellorship of the Social Democratic Party of Germany's Friedrich Ebert, the newspaper was published, with interruptions, by the Communist Party of Germany. Proscribed by the National Socialist Worker's Party government of Adolf Hitler after 1933, publication continued illegally, underground.
