This article starts from the premise that rather than being a solely contemporary notion or a concept related to the development of the European Union, European Public Sphere (EPS) should be viewed as a historically conditioned process, which draws on a longue durée of European perceptions and imaginaries constructed and disseminated in the national contexts. By looking at existent analyses of national media contents, this article, which draws on the analysis of over a hundred media studies, provides an extensive and critical examination of post-War Polish media discourses on “Europe” and “European issues” (including definitions of “Europe”, “Europeanness”, “European identity”, and “European values”). Seeing the role that those issues played in Polish media discourses during the period between 1945 and 2005 (i.e. from the end of World War II, through the development and fall of the Communism, up until and including Polish accession to the EU), the article locates when and where ethical notions related to the idea of Europe were negotiated and appropriated within media discourses. The article also attempts to fi nd examples of (possibly) transnational and event-specific aspects of reporting in order to discover the historical development of either Polish or transnational media constructions of a European Public Sphere.
