Cédric Jeanneau

Cédric Jeanneau is a Lecturer in medieval history at the University of Western Brittany, affiliated with the Breton and Celtic Research Center (CRBC) and the History Department. His academic career spans over two decades with extensive publications focusing on Western France's medieval societies, particularly the Bas-Poitou region, monastic networks, and Atlantic world dynamics.

His educational trajectory includes a Maîtrise (1996) on castle-driven societal transformations in Poitou, a DEA (2001) on Bas-Poitou castle construction, and a PhD (2006) examining spatial organization and social structures in medieval Bas-Poitou. All degrees were completed at the University of Poitiers with highest honors.

Research interests center on diplomatics, rural history, canonical communities, and monastic networks, with particular emphasis on land tenure systems, seigniorial authority, and environmental interactions in medieval Atlantic Europe. His work integrates spatial analysis with documentary evidence to reconstruct rural societies and ecclesiastical institutions.

Recent publications reveal consistent methodological focus: his 2024 monograph analyzes Bas-Poitou society through written records, while 2023 edited volumes explore ecclesiastical property across the Atlantic world. Articles demonstrate recurring themes of monastic spatial strategies, seigniorial vocabulary evolution, and aristocratic-monastic relationships, primarily utilizing diplomatic analysis of charters and cartularies.

He has supervised master's students and served as History Department Director (2013-2016). Administrative responsibilities include co-organizing 2020-2021 research days on 'The Church and the Land,' reflecting his focus on ecclesiastical property systems.

Within CRBC, he contributes to research axes on identity formation, cultural creation/reuse, and maritime consciousness, plus the transversal 'Sources and Resources' pole, leveraging his expertise in medieval documentation and spatial analysis.
