and thus known as Sveinn Alfífuson in Norway – along with his mother as guardian. They were delayed in southern Norway while Olaf's return was rebuffed but became even more unpopular than he had been. Ælfgifu tried to impose new taxation and stricter controls on a people who valued their independence and especially resented that the new customs were Danish.
Cnut also prepared to hand over Denmark to one of his sons: upon taking power in Norway, he held a great court in Nidaros and proclaimed
Harthacnut
Harthacnut (; "Tough-knot"; – 8 June 1042), traditionally Hardicanute, sometimes referred to as Canute III, was King of Denmark from 1035 to 1042 and King of England from 1040 to 1042.
Harthacnut was the son of King Cnut the Great (wh ...

would remain united after his death."
[Stenton, p. 406.] It may have been simply the custom of his people. In any event, it was clear throughout Cnut's reign that the weakness of his empire lay in the impossibility of finding loyal and competent regents to govern when he could not be present. And his sons could not hold it together.
After Cnut's death
The North Sea Empire collapsed immediately once Cnut died in 1035. In Norway, it was already collapsing: by the winter of 1033, Swein and Ælfgifu were so unpopular that they were forced to leave Trondheim. In 1034, the leader of the army that had rebuffed and killed King Olaf at Stiklestad went together with one of the king's loyal followers to bring his young son

back from
Gardariki to rule, and in autumn 1035, a few weeks before Cnut's death, Swein and his mother had to flee the country altogether and go to Denmark.
Swein died shortly afterwards.
In Denmark, Harthacnut was already ruling as king, but he was unable to leave for three years because of the threat that Magnus of Norway would invade to exact revenge. In the meantime the English nobles, divided between him and Cnut's younger son by Ælfgifu,
Harold Harefoot
Harold Harefoot or Harold I (died 17 March 1040) was regent of Kingdom of England, England from 1035 to 1037 and King of the English from 1037 to 1040. Harold's nickname "Harefoot" is first recorded as "Harefoh" or "Harefah" in the twelfth cen ...
, decided to compromise by having Harold rule as regent; by the end of 1037, Ælfgifu had persuaded the most important nobles to swear allegiance to Harold, who was firmly ensconced as Harold I – and Harthacnut's own mother, Queen Emma, had been forced to take refuge in Flanders.
Harthacnut prepared an invasion fleet to wrest England from his half-brother, but the latter died in 1040 before it could be used. Harthacnut then became king of England, reuniting it with Denmark, but made a generally bad impression as king. The ''Anglo-Saxon Chronicle'' said of him that he never did anything royal during his entire reign. He died suddenly in June 1042 "as he stood at his drink" at the wedding feast of
Tovi the Proud
Tovi the Proud (also Tofi or Tofig, Tofi pruda), , was a rich and powerful 11th-century Danish thegn who held a number of estates in various parts of southern England. A translation of the legend of Waltham Abbey cites the Lord of Waltham as 'Tovi ...
, one of the Danish thegns of his father's court. At first glance Harthacnut's death seems to have brought about the end of the North Sea Empire. However,
Magnus of Norway, utilising the agreement he had made with Harthacnut in 1040, took control of Denmark and had plans to invade England and reunite the kingdoms and Empire. In consolidating his power in Denmark he crushed a Wendish invasion at the battle of
Lyrskov Hede initiated shortly after he had destroyed the

briefly notes that Sveyn and an Earl Tovi removed Magnus from Denmark in 1047. This is confirmed by the contemporary ''Anglo-Saxon Chronicle'', which reports that in 1047 Sveyn asked England for 50 ships to help in the battle against Magnus. "And then Sveyn expelled Magnus from Denmark and entered the country by a huge carnage, and the Danes paid him a large sum of money and recognized him as king. And the same year Magnus died.'
