Harold Harefoot (c. 1015–17 March 1040) was King of England from 1035 to 1040. His cognomen "Harefoot" was for his speed, and the skill of his huntsmanship.He was the son of Canute the Great, King of England, Denmark, Norway, and some of the Kingdom of Sweden, through his handfast wife Aelgifu of Northampton. Though there was some scepticism he was really Canute's son., this was probably just propaganda by the opponents of his kingship.
Upon Canute's death (12 November 1035), Harold's younger half-brother Harthacanute, the son of Canute and his queen, Emma of Normandy, was legitimate heir to the thrones of both the Danes and the English. He was, however, unable to travel to his coronation, because his Danish kingdom was under threat of invasion by King Magnus I of Norway and King Anund Jacob of Sweden. England's magnates favoured the idea of installing Harold Harefoot temporarily as regent, due to the difficulty of Harthacanute's absence, and despite the opposition of Godwin, the Earl of Wessex, and the Queen, he eventually wore the crown.
Harold survived an attempt to unseat him led by Alfred Aetheling and Edward the Confessor, Emma's sons by the long-dead Ethelred the Unready, in 1036. Harold died at Oxford on 17 March 1040, just as Harthacanute was preparing an invasion force of Danes, and was buried at the abbey of Westminster. His body was subsequently exhumed, beheaded, and thrown into a fen bordering the Thames when Harthacanute assumed the throne in June, 1040. His supporters later rescued the body, to be buried in a church which was fittingly named St. Clement Danes.
With the north at least on Harold's side, in adherence to the terms of a deal, which Godwin was part of, Emma was settled in Winchester, with Harthacanute's huscarls. Harold soon "sent and had taken from her all the best treasures" of Canute the Great, and the Kingdom of England was practically his.
According to the Encomium Emmae, though, the Archbishop of Canterbury refused to crown Harold Harefoot. There is evidence that Aelgifu of Northampton was attempting to secure her son's position through bribes to the nobles.
