By place[edit]


  • Spring – Hugh of Provence, king of Italy, cedes Lower Burgundy to Rudolph II in return for Rudolf's reuniciation of all claims to the Italian crown. He receives the imperial crown and induces the Italian nobility to recognize his son Lothair II as the co-ruler of Lombardia (Regnum Italiae).[1]
  • King Harald I (Fairhair) dies after a 59-year reign as the Scandinavian nation's first ruler. He divides the kingdom among his many sons (about 25 years ago) to bring peace. Unable to travel through the country and perform his royal duties, Harald hands over power to his favorite son Eric I (Bloodaxe), who allegedly kills at least two of his brothers to gain the Norwegian throne that he will hold (approximate date).
  • Rollo, duke of Normandy, dies at Rouen after a 11-year reign. He is the first leader of Viking settlers who establishes a independent dukedom (a vassal of the West Frankish Kingdom). His eldest son William I (Longsword) becomes the second ruler of Normandy (approximate date).
  • Ramiro II forces the abdication of his brother Alfonso IV and becomes king of León (Northern Spain). He has him and Fruela's three sons blinded in order to make them incapable of ruling.[2]
