Until recently migration did not occupy a prominent place on the agenda of students of Roman history. Various types of movement in the Roman world were studied, but not under the heading of migration and mobility. "Migration and Mobility in the Early Roman Empire" starts from the assumption that state-organised, forced and voluntary mobility and migration were intertwined and should be studied together. The papers assembled in the book tap into the remarkably large reservoir of archaeological and textual sources concerning various types of movement during the Roman Principate. The most important themes covered are rural-urban migration, labour mobility, relationships between forced and voluntary mobility, state-organised movements of military units, and familial and female mobility.
