- Spring – The Byzantine army, led by General Melias (Domestic of the Schools in the East), continues the operations in Upper Mesopotamia.
- July: Melias moves against Amida (modern Turkey). He defeats the Arabs outside the walls, and begins to lay siege to the city. After a few days, a violent wind and a thick dust spreads over the Byzantine camp. Covered by the dust, the Arabs attack and route the Byzantines. Many of them are slaughtered and some, including Melias, are taken prisoner. Previous Byzantine gains in the area are lost. The wounded Melias dies later in captivity.
- May 7 – Emperor Otto I (the Great) dies at Memleben in Thuringia (modern Germany) after a 37-year reign. He is succeeded by his 18-year-old son Otto II (the Red), who becomes absolute ruler of the Holy Roman Empire. His mother Adelaide will exert great influence on Otto, although her lavish philanthropies will be a source of contention. Otto's succession leads to conflicts in the south German duchies and in Lotharingia.
- Edgar I (the Peaceful) is crowned king during a royal ceremony at Bath by Archbishop Dunstan. In a council at Chester, Lothian (a region of the Lowlands) is ceded to Scotland, in return for fealty from King Kenneth II.
- Edgar I marches with his army north to Chester. His navy meets him there via the Irish Sea. This show of strength persuades the 'Northern Kings' to submit to his overlordship (approximate date).
- Caliph Al-Mu'izz transfers the royal residence of the Fatimid Caliphate from El-Mansuriya (modern Tunisia) to the newly founded city of Cairo in Egypt. He leaves general Buluggin ibn Ziri to govern the Western North African territories, which will become the province of Al-Maghreb (meaning the West).
- Cloves, ginger, black pepper, and other Eastern spices are available for purchase in the marketplace at Mainz. The spices are brought to the city by Jewish traveling merchants, known as the Radhanites, who have contacts in the international trade between the Christian and Islamic world (approximate date).
- January 19 – Pope Benedict VI is consecrated as the 134th pope of the Catholic Church. He is installed at Rome with the approval of Otto I and becomes a puppet ruler of the Holy Roman Empire. The Roman aristocracy resents Otto's dominance in Roman civil and ecclesiastical affairs.
- In the Council of Winchester, Edgar I accepts a 'Monastic Agreement' (called the Regularis Concordia). The document is compiled by Bishop Æthelwold and serves as a rule for how monastic life should be performed.
