Communist propaganda was sharply critical of all integration attempts made in Western Europe. In numerous political posters and cartoons published in Poland, the brunt of the criticism was borne by the European Defense Community (EDC) from October 1950, when the idea of military integration was first proposed by French Prime Minister René Pleven, until August 1954, when a vote in the French National Assembly effectively killed the project. Through a contextualized discussion of selected posters and cartoons, which are reproduced in the text, this article relates Polish visual anti-EDC propaganda to aspects of Communist ideology, Soviet geostrategic interests, and Polish domestic politics and shows how the propaganda was intended to help the Communist authorities achieve specific goals.
