Events
By place
Byzantine Empire

Europe
- King Ferdinand I of León ("the Great") begins his campaign against al-Andalus. He conquers Seia from the Christian allies of the Muslim taifas. In a drive to consolidate his southern border in Portugal he re-populates the city of Zamora with some of his Cantabrian (montañeses) subjects.
England
- October 24 – Ælfgar, Earl of Mercia, is outlawed by the witan ("meeting of wise men"). In revenge he builds a force and allies himself with the Welsh king Gruffydd ap Llywelyn. After defeating Ralph the Timid (a nephew of King Edward the Confessor), they attack Hereford and raid the church – taking everything of value, leaving the building on fire. The rebels also attack Leominster.
- Edward the Confessor gives Tostig Godwinson (upon the death of Earl Siward) the important position as earl of Northumbria and the difficult mission of bringing the northern state under control.
