Events

September 25–28 – Rebel general Leo Tornikios (a nephew of Emperor Constantine IX) proclaims himself emperor at Adrianople, and besieges Constantinople. Byzantine troops personally led by Constantine repel him, and re-occupy the walls. Tornikios is forced to withdraw, while his followers start to abandon him. Finally, he is captured at a church in Boulgarophygon (modern Turkey), and is publicly blinded.
Winter – Constantine IX allows the Pecheneg tribes to cross the Danube and settle permanently in Byzantine territory. He buys their alliance with presents, using them to attack his enemies (Bulgars and Magyars) in the rear, and so to prevent any southward advance of the Kievan Rus'.

Spring – Henry III, Holy Roman Emperor ("the Black") travels to southern Italy, and deprives Guaimar IV of his title Duke of Apulia and Calabria. He receives homage from Drogo of Hauteville, who becomes "Duke and Master of all Italy".
August 10 – Battle of Val-ÃÂ¨s-Dunes: Norman duke William I secures control over Normandy with assistance from King Henry I of France by defeating rebel Norman barons at Caen. Later in October, William promulgates the "Truce of God" throughout his duchy.
October 25 – Harald Hardrada becomes sole king of Norway on the death of his nephew and co-regent Magnus I ("the Good"). The crown of Denmark passes to Sweyn II.
