For several years, the archaeology of contemporary conflicts has established itself as a dynamic and ever-evolving field of research. The conferences held in Verdun (2018) and Caen (2019) provided a comprehensive overview of these studies in France and beyond, while the meetings in Bordeaux (2022) marked the development of new research programs and enriched discussions on the specific methods and vocabulary of this discipline.

For the Île-de-France and Centre-Val de Loire regions, the Collective Research Program (PCR) launched in 2020, supported by the Ministry of Culture and coordinated by Gwénaël Mercé (Inrap), has set several objectives, including:

• The systematic standardized inventory of contemporary martial remains;
• The development of thematic research;
• The deepening of investigations into archival collections;
• The integration of this data into a GIS.

In the same vein, new regional programs have emerged in recent years (prospection-inventory, PCR), notably in Nouvelle-Aquitaine and Pays de la Loire.

This study day, organized by the PCR "Archaeology of Contemporary Conflicts in the Île-de-France and Centre-Val de Loire Regions," aims to:

• Present the results of its research;
• Facilitate discussions on work conducted in other regions;
• Focus specifically on issues of vocabulary, which represent a cross-cutting challenge for territories and institutions.
