Abstract

The article analyzes the reflections on nation states, and in particular the concepts of sovereignty and borders, as the thematic axis of political history studies. It therefore considers the centrality of the production and conservation of public memory through the creation of national archives and libraries, to then observe the profound changes that have taken place starting with globalization and the Internet since the 1980s. Finally, it reflects on the most recent dynamics of the twenty-first century, linked to political drives towards new forms of digital sovereignty inside the frame of a multidimensional reality – with direct repercussions on the historian’s profession
