Europe

• Summer - Arnulf of Carinthia, the King of East Francia, enlists the support of the Magyars, to raid northern Italy (Holy Roman Empire)|Italy]. They overrun the Lombard plain all the way to Pavia. King Berengar I assembles a large army against the Magyars, and confronts them near the Adda River. Daunted at the strong force, Árpád offers to make peace and restore much of what they've taken, if they are permitted to leave Italy unmolested. Berengar refuses, and the Magyars withdraw to the Brenta River. Árpád renews his offer, offering to leave all his booty and even some hostages. Again Berengar refuses, and awaits their crossing of the Brenta River for a final battle.
• September 24 - Battle of the Brenta: The Magyar forces, consisting of 5,000 men, take a circuitous route through the mountains, crossing the Brenta River and proceed south to fall upon the encamped Lombard army at Cartigliano. The Magyars massacre much of Berengar's unprepared army. He himself manages to escape to Pavia, changing his dress with the clothing of one of his soldiers. Árpád renews the offensive and heads across Lombardy, pillaging the countryside around Treviso, Vicenza, Bergamo and other towns all the way to Vercelli. He turns south and heads down the Aemilian Road, sacking Reggio Emilia, Modena and Bologna.
• December 8 - Arnulf of Carinthia dies from paralysis following a stroke and is entombed in St. Emmeram's Abbey at Regensburg. He is succeeded by his 6-year-old son Louis III as ruler of the East Frankish Kingdom. Arnulf's counselor Hatto I, archbishop of Mainz, becomes regent and guardian of the young king. Louis claims Lotharingia from his half-brother Zwentibold and with the support of the East Frankish nobles he provokes a civil war. The Lombard throne is left temporarily vacant.
• Winter - The Magyars turn back north towards the shores of the Venetian Lagoon. They pillage Chioggia and Pellestrina, and advance towards Malamocco. Their advance into the lagoon is checked by the assembly of the Venetian fleet under doge Pietro Tribuno, which defeats the Magyar's river crossing vessels at Albiola, causing them to pull back. This close call with the Magyars prompts the Venetians to initiate the fortification of the Rialto and the building of protective chains over the Grand Canal.

Britain

He seizes the royal estates at Wimborne, the ancient symbolic burial place of West Saxon kings, and Christchurch. Edward set up his army camp at Badbury Rings. Æthelwold first declares that he will 'live or die' at Wimborne, but then flees to Northumbria.
