By place

Europe

• King Charles the Younger, son of Charlemagne and ruler of Aquitaine, visits Monte Cassino and Capua, both in Beneventan territory. Prince Arechis II, feeling threatened by the Franks, decides that he needs to stop quarrelling with the Byzantine Duchy of Naples so he can focus on the Frankish foe. Prince Arechis II therefore signs a peace agreement, or 'pactum', with the Duchy of Naples.

  Britain

• Cyneheard, brother of the late king Sigeberht, ambushes and kills his rival Cynewulf of Wessex, while he is at Meretun with his mistress. The Wessex nobles refuse to recognise Cyneheard as king.
