The migrations included the Goths, Vandals, Franks, and other Germanic, Bulgar, and Slavic tribes. They may have been influenced by attacks of the Huns in the East and may also be connected to the Turkic migrations in Central Asia, overpopulation, or climate changes. The migration period also included groups of Angles, Saxons, Frisians, and some Jutes to Britain.
Migrations would continue well into the Middle Ages, beyond 1000 AD, with successive waves of Slavs, Alans, Avars, Bulgars, Hungarians, Pechenegs, Cumans, and Tatars that changed the ethnic makeup of Eastern Europe. Western European historians, however, tend to stress the migrations that were most relevant to Western Europe.
