and rival to Ælfgifu. Harthacnut's reign Upon the death of Cnut on 12 November 1035, Harold's younger half-brother Harthacnut, the son of Cnut and his queen Emma of Normandy, was the legitimate heir to the thrones of both the Danes and the English. Harthacnut, however, was unable to travel to his coronation in England because his Danish kingdom was under threat of invasion by King Magnus I of Norway and King Anund Jacob of Sweden. England's magnates favored the idea of installing Harold Harefoot temporarily as regent or joint monarch, due to the difficulty of Harthacnut's absence, and despite the opposition of Godwin, the Earl of Wessex, and the Queen, he eventually wore the crown. There is some dispute in primary sources (the Anglo-Saxon Chronicle) about Harold's initial role. Versions E and F mention him as regent, the others as co-ruler. Ian Howard points out that Cnut had been survived by three sons: Svein, Harold, and Harthacnut. The Encomium Emmae Reginae also describes Edward the Confessor and Alfred Aetheling as the sons of Canute, though the modern term would be step-sons. Harold could claim the regency or kingship because he was the only one of the five present in England in 1035. Harthacnut was reigning in Denmark, and Svein had joined him there following his deposition from the Norwegian throne, while Edward and Alfred were in Normandy. Harold could reign in the name of his absent brothers, with Emma rivaling him as a candidate for the regency. The Anglo-Saxon Chronicle ignores the existence of Svein, or his claim to the throne, which Howard considers as evidence of the relative entries being unreliable, of failing to give a complete picture. The Heimskringla of Snorri Sturluson claims that Svein and Harthacnut had agreed to share the kingdom between them. This agreement would include Denmark and (probably) England. Snorri quotes older sources on the subject and could be preserving valuable details. Reign Assumption of the throne Harold reportedly sought coronation as early as 1035. According to the Encomium Emmae Reginae, however, Æthelnoth, Archbishop of Canterbury, refused to crown Harold Harefoot. Coronation by the Archbishop would be a legal requirement to become a king. Æthelnoth reportedly placed the sceptre and crown on the altar of a temple, possibly that of the Canterbury Cathedral. Offering to consecrate Harold without using any of the royal regalia would have been an empty honour. He refused to remove
