Europe

 * Spring – King Conrad II, "the Elder", assembles an army of thousands of armored knights for an expedition into Italy. He besieges Pavia and marches to Milan, where he is crowned with the Iron Crown by Archbishop Aribert as king of the Lombards. Duke William V ("the Great") of Aquitaine, who is already en route for Italy, decides to renounce his claim to the Lombard throne and turns back.
 * April – Conrad II punishes the citizens of Pavia with starvation, with the help of Milanese troops, for burning down the Royal Palace. He appoints Aribert as his viceroy ("imperial vicar") in Italy and charges him to ensure that the order is complied with.
 * Summer – Conrad II leaves the bulk of his army at the siege of Pavia, and marches to Ravenna. The Ravennan militias close the town gates and assault the imperial train. Conrad rallies his troops and takes Ravenna, taking bloody revenge.
 * 1 June – The Basilica of Saint Maternus in Walcourt, present-day Belgium, is consecrated by Bishop Réginhard of Liège.
 * Conrad II proceeds to Pesaro, but a malarian outbreak forces him to withdraw back up north to the Po Valley. He subdues the March of Turin, where Count Ulric Manfred II opposes the election of Conrad.
 * Autumn – Pavia falls to the imperial forces. Only the intervention of Odilo of Cluny persuades Conrad to have mercy on the city and the defeated rebels.
 * Battle of Helgeå (off the coast of Sweden): Naval forces of King Cnut the Great's North Sea Empire defeat the combined Swedish and Norwegian royal fleets.
