This article addresses the influence of personalism – an anti-liberal, anti-socialist intellectual movement which developed in France in the 1930s – on the process of European integration during the European Commission presidency of Jacques Delors (1985–95). The received wisdom is that the personalist tradition contributed to shaping the early developments in European integration in the 1950s but its influence later declined with the consolidation of the bipolar equilibrium in Europe. Instead, this work shows that personalism gradually re-emerged during the mid-1970s and 1980s and inspired the Commission's search for an anti-individualist European social model, the supranational democratisation of the integration process and the continental vision of European integration after 1989.
