King Canute the Great of England and Denmark dies on November 12, 1035. Rule of the empire was disputed and divided, between his sons: Harold Harefoot and Harthacnut.
Harold was crowned King of England in 1037. Harthacnut ruled Denmark and the North Sea empire and became king of both England and Denmark after Harolds death in 1040. Harthacnut rule was unpopular and his sudden death in 1042 ended the union and restored the Anglo-Saxon line in England with the ascension of Edward the Confessor.
