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.
