The authors of the seven essays included in this collective work are a group of young, promising doctoral students from the Doctoral School in Politics and Institutions at the Catholic University of Sacred Heart of Milan. In the 2021-2022 academic year, as required by the doctoral programme, they attended a cycle of seminars ( Workshop of History 2021-2022) on “Utopias, Dystopias and Diachronies in Contemporary State-building”, sponsored by the Department of Political Science under the “The Clash of Narratives” project. The Workshop of History 2021-2022 aimed to look at the great constitutional architectures of the contemporary age, interpreting them as they would any utopian project, and as such, seeing them often contradicted, disregarded or even shipwrecked in political and institutional practice.
