Year 631 (DCXXXI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. The denomination 631 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

  • Emperor Heraclius appoints Cyrus, patriarch of Alexandria, with power to act as viceroy (dioikesis) of Egypt. He begins a 10-year persecution against the non-Chalcedonian Coptic Christians.
  • Europe

  • Battle of Wogastisburg: The Slavs under King Samo defeat the Austrasian Franks, in a three-day battle near Trenčín (modern Slovakia). King Dagobert I is forced to retreat; the Franks with their allies are slaughtered. Samo invades Thuringia and undertakes looting raids.
  • King Suintila is overthrown after a 10-year reign by his son Sisenand, with the aid of Dagobert I. The Visigothic nobles offer him a 500-pound plate made of pure gold. Sisenand becomes new king of the Visigothic Kingdom and declares his father a tyrant for his many crimes.
  • The Saxons (Northern Germany) appeal to Dagobert I, against the yearly tribute (500 cows) which they still pay (approximate date).
