## Events

### By place

**Byzantine Empire**

* June 18 – Byzantine–Rus' War: A fleet of about 200 Rus' vessels sails into the Bosphorus, and starts pillaging the suburbs of Constantinople. The raiders set homes on fire, and drown and kill the citizens. Unable to do anything to repel the invaders, Patriarch Photios I urges his flock to implore the Theotokos to save the Byzantine capital. Having devastated the suburbs, the Rus' Vikings pass into the Sea of Marmara and attack the Isles of the Princes, plundering the local monasteries.

**Europe**

* King Charles the Bald gives the order to build fortified bridges across the Seine and Loire Rivers, to protect Paris and the Frankish heartland against Viking raids. He hires the services of Weland, a Viking chieftain based on the Somme, to attack the Seine Vikings at their base on the Isle of Oissel. Weland besieges the Vikings—they offer him a huge bribe (6,000 pounds of silver) to let them escape.
* Summer – The Viking chieftains Hastein and Björn Ironside ravage upstream and move to Italy, sacking Luna (believing it to be Rome). They sail up the River Arno to sack the cities of Pisa and Fiesole (Tuscany).
* Summer – Viking raiders led by Weland sail to England and attack Winchester (the capital of Wessex), which is set ablaze. He spreads inland, but is defeated by West Saxon forces, who deprive him of all he has gained.
* December 20 – King Æthelbald of Wessex dies after a 2½-year reign. He is succeeded by his brother, sub-king Æthelberht of Kent, who becomes sole ruler of Wessex.
