Julien Bachelier

Julien Bachelier serves as Lecturer in medieval history at the Breton and Celtic Research Center (CRBC, EA 4451), affiliated with the University of Western Brittany. His academic profile centers on Breton historical geography with specialized focus on settlement networks, urban morphology, and maritime exchanges during the medieval period. Administrative responsibilities include Directorship of the IUP Patrimoine program at Quimper and oversight of the Ecclesia publication series at CRBC Editions.

Dr. Bachelier's research investigates the formation processes of agglomerated centers in medieval Brittany, emphasizing interdisciplinary methodologies that integrate morphological analysis with textual and archaeological evidence. His work particularly examines coastline dynamics and river-maritime exchange systems, revealing how these factors shaped settlement patterns in Haute-Bretagne from the 11th to 14th centuries. Current projects explore monastic networks, frontier formation, and the spatial organization of medieval Breton communities through rigorous source criticism and spatial analysis techniques.

Analysis of his recent publications (2019-2025) demonstrates consistent specialization in medieval Breton urban history, with increasing attention to manuscript studies, monastic economies, and frontier dynamics. His scholarly output reveals methodological innovation through cross-disciplinary source integration, particularly in studies of cartularies, urban morphology, and maritime trade routes. Key thematic trajectories include the role of castles in settlement dynamics, wine production economies, and the formation of political boundaries between Brittany and neighboring principalities.

Within the CRBC research framework, Bachelier actively contributes to Axes 2 (De la création au remploi) and 3 (Conscience(s) du maritime), organizing significant academic events including the 2022 study day on Fougères' urban history and 2021 research on Breton coastlines during the early Middle Ages. His leadership in the IUP Patrimoine program underscores commitment to heritage education in western Brittany's academic institutions.
