Events

At the invitation of Benevento, the newly-restored Byzantine fleet appears in the waters off Otranto. On the orders of Emperor Basil I, the Byzantines sail up the Adriatic Sea and reconquer part of southern Italy. The city of Bari is occupied in the name of the Byzantine Empire. Instead of holding it for his 'ally' Adelchis of Benevento, Basil makes it the capital of the new Byzantine Theme of Longobardia.^[1]^[2]

August 28 – King Louis the German dies at Frankfurt, while preparing for war against his brother Charles II ("the Bald"), ruler of the Holy Roman Empire. The East Frankish Kingdom is divided among his three sons: Carloman receives Bavaria and styles himself "King of Bavaria". Louis the Younger receives Saxony (with Franconia and Thuringia), and Charles the Fat receives Swabia (with Raetia).
October 8 – Battle of Andernach: Frankish forces, led by Louis the Younger, prevent a West Frankish invasion and defeat Charles II at Andernach. The Rhineland remains part of the East Frankish Kingdom.

The Great Heathen Army, led by Guthrum, captures the fortress of Wareham (Dorset), and is met by a Viking army (3,500 men) from the sea, which lands at Poole Harbour. King Alfred the Great traps the Vikings, and demands hostages in return for a peace agreement. The Danes divide their forces; half flees to Exeter, where they besiege the town while the other half escape in their ships, but are lost in a storm near Swanage.^[3]
Viking leader Halfdan Ragnarsson formally establishes the Danish kingdom of York, after the removal of the puppet king Ricsige of Northumbria, and becomes the first monarch.

April 8 – Battle of Dayr al-'Aqul: Abbasid forces, led by Al-Muwaffaq, halt a Saffarid invasion on the River Tigris. Emir Ya'qub ibn al-Layth tries to capture the Abbasid Caliphate's capital of Baghdad, but he is forced, with his army, to retreat.

Emperor Seiwa abdicates the throne, in favor of his 7-year-old son Yōzei. Seiwa becomes a Buddhist priest; he appoints Fujiwara no Mototsune as regent (sesshō), who assists the child emperor.

June – Synod of Ponthion: Charles II summons a council, in which a papal brief is read from Pope John VIII. He appoints Ansegisus as papal legate and primate over Gaul, in the West Frankish Kingdom.
John VIII travels throughout Campania, in an effort to form an alliance among the southern Italian states (the cities of Salerno, Capua, Naples, Gaeta and Amalfi) against Muslim raids.
