Harthacnut was the son of King Cnut the Great (who ruled Denmark, Norway, and England) and Emma of Normandy. When Cnut died in 1035, Harthacnut struggled to retain his father's possessions. Magnus I took control of Norway, but Harthacnut succeeded as King of Denmark and became King of England in 1040 after the death of his half-brother Harold Harefoot, king of England. Harthacnut himself died suddenly in 1042 and was succeeded by Magnus in Denmark and Edward the Confessor in England. Harthacnut was the last Dane to rule England.
