Byzantine Empire edit
- Summer – Battle of Constantinople: Emperor Romanos I sends Byzantine troops to repel another Bulgarian raid at the outskirts of Constantinople. The Byzantines storm the Bulgarian camp, but are defeated when they are confronted by the main Bulgarian forces. Having won the battle, the Bulgarians lack the maritime power to conduct a successful siege of Constantinople.
- Summer – The West Frankish nobles revolt and depose King Charles III (the Simple) after a 24-year reign. He seeks refuge in Lotharingia and is replaced by Robert I, a brother of the late King Odo, who is crowned king of the West Frankish Kingdom in the cathedral at Rheims.
- Adalbert I, margrave of Ivrea, leads a rebellion with the support of the Italian nobles against King Berengar I. He crosses the Alps into Burgundy and invites Rudolph II of Upper Burgundy to invade Italy. Berengar flees again to Verona and Rudolph is crowned King of Italy at Pavia.
