Through England, Æthelred the Unready and Holy Roman Empire

Harthacnut was the son of King Cnut the Great, who ruled Denmark, Norway, and England, and Emma of Normandy. After Cnut's death in 1035, Harthacnut faced challenges in retaining his father's territories. Magnus I seized control of Norway, while Harthacnut succeeded as King of Denmark. In 1040, following the death of his half-brother Harold Harefoot, he became King of England. Harthacnut died suddenly in 1042 and was succeeded by Magnus in Denmark and Edward the Confessor in England. He was the last Dane to rule England.

Early life

Harthacnut was born shortly after the marriage of his parents in July or August 1017. Cnut had set aside his first wife, Ælfgifu of Northampton, to marry Emma, and according to the Encomium Emmae Reginae, a book she commissioned many years later, Cnut agreed that any sons from this marriage would take precedence over the sons of his first marriage. In 1023, Emma and Harthacnut played a leading role in the translation of the body of the martyr St Ælfheah from London to Canterbury. Harthacnut's biographer, Ian Howard, sees this event as recognition of his position as Cnut's heir in England.

In the 1020s, Denmark faced threats from Norway and Sweden. In 1026, Cnut decided to strengthen its defences by sending his eight-year-old son to Denmark as the future king under a council headed by his brother-in-law, Earl Ulf. Ulf alienated Cnut by persuading the Danish provinces to acknowledge Harthacnut as king without reference to Cnut's overall authority and by failing to take vigorous measures against Norwegian and Swedish invasions, instead waiting for Cnut's assistance. In 1027, Cnut arrived with a fleet, forgave Harthacnut his insubordination in view of his youth, but had Ulf murdered. He drove the invaders out of Denmark and established his authority over Norway, returning to England in 1028 and leaving Denmark under Harthacnut's rule.

Cnut had left Norway under the rule of Håkon Eiriksson, who drowned in a shipwreck in 1029 or 1030. Cnut then appointed his son Svein to rule Norway with the assistance of Ælfgifu, Cnut's first wife and Svein's mother. They made themselves unpopular through heavy taxation and by favouring Danish advisers over the Norwegian nobility. When King Magnus I of Norway, the son of former King Olaf, invaded in 1035, Svein and Ælfgifu were forced to flee to Harthacnut's court. Harthacnut was a close ally of Svein, but he did not consider his resources sufficient to launch an invasion of Norway. The half-brothers sought help from their father, only to learn of his death in November 1035.
