Events

By place

Europe

• The Treaty of Verdun divides the Carolingian Empire between the 3 sons of Louis the Pious (Charles the Bald, Lothar and Louis the German).
• Kenneth I (Cináed mac Ailpín), King of the Scots, also becomes King of the Picts, thus becoming the first monarch of the new nation of Scotland. The Alpin dynasty of Scottish kings begins to reign.
• The Battle of Messac is won by Erispoe, son of Nominoe, Count of Vannes, against Renaud d'Herbauges who is prefet of the Marks of Brittany. Renaud d'Herbauges had tried an attack while Nominoe was ill. This battle marks the beginning of the hostilities between Charles the Bald and Nominoe.
• Al-Andalus: The city of Saragossa rises against the Umayyad emir.

Asia

• In the Tang Dynasty Chinese capital of Chang'an, a large fire consumes 4,000 homes, warehouses, and other buildings in the East Market, yet the rest of the city is at a safe distance from the blaze (which is largely quarantined in East Central Chang'an thanks to the large width of roads in Chang'an that produce fire breaks).

By topic

Religion

• The iconoclastic controversies end in Byzantium with the widow of Emperor Theophilus, Theodora II, acting as regent for her son, the future Michael III. Theodora II restored the veneration of icons in the Eastern Church, thus ending Iconoclasm.
