The ‘école barisienne’ refers to a group of intellectuals, active between the end of the 1960s and the beginning of the 1980s, who brought their academic and political activity together in order to bring the cultural heritage of Italian communism up to date and to construct a new theory of the revolution. Interpreting the student movement of 1968 as the historical agent of a social and political revolution, their intention was to transform the Italian Communist Party (PCI) into a ‘partito-società’ (‘party-society’) that could take hold of the new generation’s demand for democracy and overturn the hegemony of Christian Democracy, understood as the ‘partito-Stato’ (‘party-state’). This article retraces the life of this intellectual grouping, from the education of its proponents, marked by the Southern Question as a national question, through to the demise of their project. Specifically, it examines the relationship between the research activity of the école, highlighting some significant analytical categorisation used in its historiographical output, its political activity, and the national position of the PCI.
