Byzantine Empire
- Spring – Allied with the Rus', a Hungarian army raids Moesia and Thrace. Emperor Romanos I buys peace, and accepts to pay a yearly tribute (protection money) to the Hungarians. His frontiers now 'protected' on the Balkan Peninsula, Romanos sends a Byzantine expeditionary force (80,000 men) led by general John Kourkouas (his commander-in-chief) to invade northern Mesopotamia (modern Iraq).
Europe
- Caspian expeditions of the Rus': The Rus' under the Varangian prince Igor I of Kiev sail up the Kura River, deep into the Caucasus, and defeat the forces of the Sallarid ruler Marzuban ibn Muhammad. They capture the fortress city of Barda (modern Azerbaijan).
- Battle of Wels: A joint Bavarian–Carantanian army led by Bertold (duke of Bavaria) defeats the Hungarians near Wels (Upper Austria), who are attacked at a crossing of the Enns River at Ennsburg.
England
