By place
Byzantine Empire
- Sultan Tughril leads a large Seljuk army out of Azerbaijan into Armenia, possibly to consolidate his frontier, while providing an incentive to his Turkoman allies in the form of plunder. Tughril divides his army into four columns, ordering three to veer off to the north to raid into central and northern Armenia, while he takes the fourth column towards Lake Van. The Seljuk Turks capture and sack the fortress city of Artchesh, after an 8-day siege.[1]
Europe
- Battle of Mortemer: The Normans, led by Duke William (the Conqueror), defeat a French army (near Mortemer), as it is caught pillaging and plundering. King Henry I of France withdraws his main army from the Duchy of Normandy as a result. Guy I, Count of Ponthieu, is captured during the course of the battle.
Scotland
- July 27 – Siward, earl of Northumbria, invades Scotland, to support King Malcolm III against Macbeth, who has usurped the Scottish throne from Malcolm's father, Duncan I. Macbeth is defeated at Dunsinane.
Africa
- The Almoravids retake the trading center of Aoudaghost from the Ghana Empire. Repeated Almoravid incursions, aimed at seizing control of the trans-Saharan gold trade, disrupt Ghana's dominance of the trade routes.[2]
