This research seminar aims to contribute to the structuring of a research network on ‘Overseas’ in the social sciences. Starting from the French case, but not limited to it (and thus extending the reflection to territories which, in one way or another, are in a situation of non-sovereignty or restricted sovereignty), the aim is to explore, in particular, post-colonial situations of political, economic and health dependence; the specific questions raised by the governance and uses of the maritime domain, and more broadly of natural resources; the reconfiguration of relations between the ‘South’ and the ‘North’ from the point of view of globalisation or the articulation between public policies and indigenous knowledge. The seminar programme is designed with the support of a multidisciplinary scientific team (history, anthropology, sociology, political and legal sciences).
