In 1918, Heartfield began at the Berlin Dada scene, and the Communist Party of Germany. He was thrown out of the Reichswehr film service because he supported the strike after the assassination of Karl Liebknecht and Rosa Luxemburg. With George Grosz, he founded "Die Pleite", a satirical magazine. Heartfield started to work for two communist publications: the daily Die Rote Fahne ("The Red Flag")and the weekly Arbeiter-Illustrierte-Zeitung (AIZ)("Workers' Illustrated Newspaper"). AIZ published Heartfield's most famous work
