The history of medieval Christianity is, in many respects, a history of movement. Although the Middle Ages are often imagined as an age of immobility, characterized by localism, agrarian routines, and limited communication, the religious life of medieval Europe was profoundly shaped by people who traveled. Pilgrims crossed continents in pursuit of holy shrines, merchants carried not only goods but also ideas across vast distances, rulers journeyed through their territories to exercise authority, and scholars migrated between schools and courts. Among these mobile figures, however, few proved as influential as the itinerant evangelists whose preaching, missionary activity, and religious example contributed decisively to the expansion, consolidation, and transformation of Christian society.
This book examines the phenomenon of itinerant evangelization in the Middle Ages, tracing its development from the post-Roman world of Late Antiquity to the closing centuries of the medieval period. It seeks to understand how individuals and communities devoted to spreading Christian teachings used mobility as a religious strategy, how their efforts shaped the spiritual geography of Europe and beyond, and how the ideal of the traveling preacher became one of the most enduring features of medieval religious culture.
