Migration theories

The Migration Period was a time of widespread migrations of peoples, notably the Germanic tribes and the Huns, within or into Europe in the middle of the first millennium AD. It has also been termed in English by the German loanword Völkerwanderung and—from the Roman and Greek perspective—the Barbarian Invasions. Many of the migrations were movements of Germanic, Hunnic, Slavic, and other peoples into the territory of the then Roman Empire with or without accompanying invasions or war.
