Europe

• Summer - King Arnulf of Carinthia enlists the support of the Magyars to raid northern 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.
• 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

• October 26 - King Alfred the Great dies after a 28-year reign in which he has forced invading Danish Vikings to withdraw, consolidated England around Wessex, divided parts of Mercia into shires, compiled the best laws of earlier kings, encouraged learning by bringing famous scholars to Wessex and made his own translations of Latin works. He is succeeded by his eldest son, Edward the Elder as king of Wessex.
• Winter - Æthelwold's Revolt: Following the death of Alfred the Great, Æthelwold disputes the succession of Edward the Elder. He seizes the royal estates at Wimborne, the ancient symbolic burial place of West Saxon kings, and Christchurch. Edward set up its army camp at Badbury Rings. Æthelwold first declares that he will 'live or die' at Wimborne, but then flees to Northumbria.

  Arabian Empire

• Muhammad ibn Ahmad al-Shaybani, Muslim ruler of Diyar Bakr, surrenders at the besieged capital of Amid to Caliph Al-Mu'tadid in exchange for clemency. Al-Muktafi, the son of Al-Mu'tadid, is installed as governor of the Jazira, ending the semi-independent Shaybanid Dynasty, which has ruled in Diyar Bakr since the 870s.
• The Qarmatians, led by Abu Sa'id al-Jannabi, capture Bahrain's capital of Hajr and Al-Hasa. Abu Sa'id makes it his residence and establishes a religious utopian republic.
