• July 11 – King Rudolph II of Burgundy dies after a 25-year reign, and is succeeded by his 12-year-old son Conrad I ("the Peaceful"). His wife, Queen Bertha, takes effective control of unified Burgundy, transferring its capital to Arles (that Burgundian kingdom was later known from the 12th century as the Kingdom of Arles).^[1]
• King Otto I refuses to give land to his older (illegitimate) half-brother Thankmar, who gains the support of Eberhard III (duke of Franconia) and Wichmann the Elder, and seizes the fortress of Eresburg. Otto assumes direct rule over Franconia, and dissolves it into smaller counties.^[2]
