The Migration Period was a period of large-scale migrations with or without accompanying invasions or war in Europe. It is often defined as starting from the period when it seriously impacted the Roman world, running from about 376 to 800 AD during the transition from Late Antiquity to the Early Middle Ages. This period was marked by profound changes both within the Roman Empire and beyond.
