The Migration Period, also called Barbarian Invasions or Völkerwanderung (German for "wandering of peoples"), is a name given by historians to a human migration which occurs within the period of roughly 300–700 in Europe, marking the transition from Late Antiquity to the Early Middle Ages.The migration includes the Goths, Vandals, Suebi and Franks, among other Germanic, Bulgar and Slavic tribes.

The migration may have been triggered by the incursions of the Huns, in turn connected to the Turkic migration in Central Asia, population pressures, or climate changes.Migrations will continue well beyond 1000, successive waves of Slavs, Alans, Avars, Bulgars, Hungarians, Pechenegs, Cumans, and Tatars radically changing the ethnic makeup of Eastern Europe.

Western European historians, however, tend to emphasize the migrations most relevant to Western Europe.
