Events

Spring – Emperor Constantine IX Monomachos sends a Byzantine expeditionary force to the Balkans against the rebellious George Maniakes, governor of the Catepanate of Italy. The two armies meet near Thessaloniki in northern Greece. The rebel army – better organized, seasoned and with superior leadership – is initially successful, but Maniakes is killed by an arrow at the moment of his triumph. After this, his army is routed.
Rus'–Byzantine War: A Kievan Rus' naval raid, led by Grand Prince Vladimir Yaraslavich, unsuccessfully attacks Constantinople. A 6,000-strong Kievan contingent under Vyshata is also defeated and deported to the capital.

Spring – A grand assembly at Melfi, with all the Norman and Lombard nobles acclaim Guaimar IV, duke of Apulia and Calabria. The territories are divided into 12 fiefdoms and distributed among Norman chieftains. William Iron Arm is granted Ascoli as a private fiefdom and his brother Drogo of Hauteville is granted Venosa. Count Rainulf II of Aversa, not present at the assembly, receives Siponto and recognizes Guaimar's suzerainty.
Grand Prince Yaroslav the Wise of Kyiv makes an agreement with Duke Casimir I the Restorer of Poland that recognizes Chervyen as part of Kiev. The agreement is sealed with a double marriage – Casimir to Maria Dobroniega (a daughter of Vladimir the Great), and Iziaslav to Gertrude, Casimir's sister.^[1]
November 21 – King Henry III ("the Black") marries Agnes of Poitou (daughter of William V of Aquitaine) at the Imperial Palace at Ingelheim am Rhein. She is his second wife after the death of Gunhilda from malaria in 1038.

April 3 – Edward the Confessor is crowned king of England at Winchester Cathedral. He learns that his mother, Queen Emma of Normandy is plotting with Magnus the Good to take control of the English throne. Edward strips her land and treasure, but she is allowed to stay in England.

The Seljuqs under Tughril Beg expel the Oghuz Turks from Khorasan and conquer Qazvin (modern Iran). They become the new masters of the Ziyarid dynasty (approximate date).

In China, the statesmen Ouyang Xiu and Fan Zhongyan put forth the Qingli Reforms during the Song dynasty, which are halted by 1045.
