The migration period, or barbarian invasions or Völkerwanderung happened in AD 300–700 in Europe, at the end of ancient history and during the Early Middle Ages.

2nd to fifth century simplified migrations. See also map of the world in AD 820.

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.
