Social mobility in the pre-industrial era has become a key topic in historiographical debate, with implications for the present. This volume examines the sources, methods, and dynamics of the phenomenon through both quantitative and qualitative approaches. The collection is structured into six areas: study methodologies, links with economic growth and inequality, geographical and demographic mobility, the impact of family structures and inheritance systems, dynamics of social decline, and the perception of mobility. The use of interdisciplinary tools provides new perspectives on understanding social trajectories in the past.
