This chapter examines migration in Late Antiquity, focusing on the movement of peoples and its role in shaping the post-Roman world. It challenges traditional narratives of mass invasions, instead emphasising the complexity of migration processes and their varied effects on political, social and cultural transformations. The chapter draws on archaeological evidence, including settlement patterns, burial practices and material culture, alongside historical sources such as chronicles. It highlights key migration episodes, including the movements of the Goths, Anglo-Saxons and Slavs, analysing how their settlements and artefacts reflect patterns of mobility, integration and adaptation. The chapter also considers new methodologies, such as isotope and aDNA analysis, to refine our understanding of ancient migrations. Central is the notion that migration was not always a violent invasion but often a gradual, negotiated process. While some groups displaced populations, others integrated with existing societies. The chapter stresses that the scale and nature of migration varied and calls for an interdisciplinary approach, combining archaeology, history and scientific methods, to better assess the role of migration in the transition from the Roman world to medieval Europe.
