Europe

 * June 12 – Battle of Augsburg: The Hungarians defeat the East Frankish army under King Louis IV (the Child), using the famous feigned retreat tactic of the nomadic warriors. Count Gausbert, the actual commander of the East Frankish army (because Louis IV is only 16 years old at this time), is killed in the battle.
 * June 22 – Battle of Rednitz: The Hungarians defeat the East Frankish army near the Rednitz River, killing its leader Gebhard, Duke of Lotharingia (Lorraine). After the battle Louis IV, together with the East Frankish duchies Franconia, Lotharingia, Bavaria and Saxony, agrees to pay tribute to the Hungarian state.
 * Summer – King Alfonso III of Asturias is forced to abdicate the throne and partitions the kingdom among his three sons. The eldest son, García I, becomes king of León. The second son, Ordoño II, reigns in Galicia, while the third, Fruela II, receives Asturias with Oviedo as his capital.

Britain

 * August 5 – Battle of Tettenhall: King Edward the Elder attacks the joint-Kings Eowils and Halfdan of Norse York. All three Viking monarchs are killed in battle (one chronicle mentions a third brother) and the Viking army is decisively defeated by allied forces of Mercia and Wessex. The co-Kings are succeeded by Ragnall ua Ímair.

Religion

 * William I (the Pious) of Aquitaine, donates land in Burgundy for the building of a Benedictine monastery dedicated to the saints Peter and Paul. Hence the Abbey of Cluny, becomes the largest in the West. In the foundation charter, William renounces all rights to the monastery and nominates Berno as the first abbot of Cluny (Eastern France).
