Late antiquity was, for the Roman World, the period of larger formal expansion, in
geographical, political and cultural terms, but also the moment of great challenges: internal
disaggregation, and the menace the barbarians entering in the Roman limes. This work is
intended to illustrate the importance of the facts from late antiquity and Roman political
measures on the contemporary configuration of Europe, who inherited the Roman efforts to
preserve unity and a stable model of civilisation.
