Introducing CRHIA

The Center for Research in International and Atlantic History (UR 1163 – Nantes University and La Rochelle University) is one of the major historical research centers in Western France, accredited by the Ministry of Higher Education and Research under the 2021–2026 five-year contract.

Our laboratory brings together researchers in ancient history, medieval history, modern history, contemporary history, literature, and languages. In total, it includes 132 members (46 tenured faculty members, 9 emeritus professors, 1 postdoctoral researcher, 6 early-career doctors, 47 doctoral students, and 8 administrative and technical staff) as well as 114 affiliated researchers, all working around a common theme:

From the World to the Atlantic, and from the Atlantic to the World:

the processes, spaces and actors of international exchange

from antiquity to the present

Our global project for 2017-2021 relies on three main research themes:

Research theme 1

Flows of people, things and knowledge : connections and reconfigurations


Research theme 2

Rivalry and negociations : international relations, diplomacy and war


Research theme 3

The dynamics of Alterity : representations and governance of cultural and religious group

Finally, the CRHIA benefits from a double accreditation, the main academic institution is the University of Nantes and the secondary one is the University of La Rochelle.
