Harold Harefoot was the son of Canute and his first wife, Elfgifu. The brothers began by sharing the kingdom of England after their father's death - Harold Harefoot becoming king in Mercia and Northumbria, and Harthacanute king of Wessex. During the absence of Hardicanute in Denmark, his other kingdom, Harold Harefoot became effective sole ruler in 1037. On his death in 1040, the kingdom of England fell to Hardicanute alone.
