Events

End of the Pecheneg Revolt: Emperor Constantine IX Monomachos makes peace with the Pechenegs. However, Pecheneg raids do not cease; they not only damage the economy by plundering, but Constantine is also forced to buy protection or peace from them by gifts, land grants, privileges and titles.<ref>Template:The Early Medieval Balkans</ref>

June 18 – Battle of Civitate: Norman horsemen (3,000 men), led by Humphrey of Hauteville, count of Apulia and Calabria, rout the combined forces under Pope Leo IX, in Southern Italy. The Normans destroy the allied Papal army and capture Leo, who is imprisoned (as a hostage for 8 months) in Benevento.
