Emma went into exile in Flanders until Harthacnut became king following Harold's death in 1040, and his half-brother Edward followed Harthacnut to England ; Edward was proclaimed king after Harthacnut's death in June 1042.

In 1035, the throne of England was reportedly claimed by Alfred Ætheling, younger son of Emma of Normandy and Æthelred the Unready, and half-brother of Harthacnut.

In contempt of Harthacnut, and at war with his enemies in Scandinavia, Alfred was captured, blinded, and shortly after, died from his wounds.

Edward was subsequently King of England on the death of Harthacnut, who, like Harold I, met his end in the throes of a fit.

He appeared to have a slim prospect of acceding to the English throne during this period, and his ambitious mother was more interested in supporting Harthacnut, her son by Cnut.

Harthacnut, his position in Denmark now secure, did plan an invasion, but Harold died in 1040, and Harthacnut was able to cross unopposed with his mother to take the English throne.

According to the Anglo-Saxon Chronicle Edward was sworn in as king alongside Harthacnut, but a diploma issued by Harthacnut in 1042 describes him as the king's brother.

Harthacnut (" Tough-knot "; ; c. 1018 – 8 June 1042 ) was King of Denmark from 1035 to 1042 and King of England from 1040 to 1042.

Harthacnut died suddenly in 1042, and was succeeded by Magnus in Denmark and Edward the Confessor in England.

Harthacnut was born shortly after his parents ' marriage in July or August 1017.

Harthacnut was a close ally of Svein, but he did not feel his resources were great enough to launch an invasion of Norway, and the half-brothers looked for help from their father, but instead they received news of his death in November 1035.

In 1037, Harold was generally accepted as king, Harthacnut being, in the words of the Anglo-Saxon Chronicle, " forsaken because he was too long in Denmark ", and Emma fled to Bruges, in Flanders.

In 1039, Harthacnut sailed with ten ships to meet his mother in Bruges but delayed an invasion as it was clear Harold was sick and would soon die, which he did in March 1040.

M. K. Lawson in his Dictionary of National Biography article on Harthacnut states that it is unclear whether Harthacnut was to have England as well as Denmark, but it was probably a reflection of a formal arrangement that mints south of the Thames produced silver pennies in his name, while those to the north were almost all Harold's.

Svein died shortly before it was to set out but Harthacnut proceeded anyway.

War was avoided by the treaty between Harthacnut and Magnus, which Harthacnut agreed to because he had no plausible candidate to rule Norway after Svein's death, and he was in any case temperamentally inclined to avoid campaigns and wars.

When Harthacnut himself died in 1042 Godwin supported the claim of Æthelred's last surviving son Edward the Confessor to the throne.

The Knýtlinga saga treats the death of Harthacnut as the end of an ancient line of kings, and notes that he was the last Danish king to rule over England.

The rulers of Bernicia held the title of High Reeve of Bamburgh from at least 913 until 1041, when the last was killed by Harthacnut ; sometimes-954-963 and 975-1016-they also served as Earls of York.

Harthacnut prepared an invasion force after he had made his Danish Lands secure in 1040 and picked Emma up from Flanders before setting out to England.

He had succeeded Cnut the Great's son Harthacnut, restoring the rule of the House of Wessex after the period of Danish rule since Cnut had conquered England in 1016.

However, Ulf alienated Cnut by getting the Danish provinces to acknowledge Harthacnut as king without reference to Cnut's overall authority and by failing to take vigorous measures to meet Norwegian and Swedish invasions, instead waiting for Cnut's assistance.

Harthacnut, however, was unable to travel to his coronation in England because his Danish kingdom was under threat of invasion by King Magnus I of Norway and King Anund Jacob of Sweden.

Emma Mason speculates that Cnut had build a royal residence in the vicinity of the Abbey, or that Westminster held some significance to the Danish Kings of England, which would also explain why Harthacnut would not allow a usurper to be buried there.

Harthacnut was the semi-legendary founder of the Danish royal house at the beginning of the tenth century, and his son, Gorm the Old, was the first in the official line ( the ' Old ' in his name being to this effect ).

Since Harthacnut was already on the Danish throne, this reunited the North Sea Empire.

After the death of Harthacnut, which had left the Danish throne vacant, Magnus had in addition been selected to be the king of Denmark, and thereafter also managed to defeat the Danish royal pretender Sweyn Estridsson.

When Harthacnut died, the English nobles had chosen as their king Æthelred the Unready's son Edward ( later known as Edward the Confessor ); Magnus wrote to him that he intended to attack England with combined Norwegian and Danish forces and " he will then govern it who wins the victory.

Gorm is the reported son of semi-legendary Danish king Harthacnut.

Svend was made jarl under Danish king Harthacnut, and led a campaign for him against Norway, but was beaten by Magnus I of Norway.

When Harthacnut died in 1042, Magnus claimed the Danish throne and made Svend his jarl of Jutland.

However as Harald did not marry, his brother Cnut the great became king, re-established the Danish Empire and married Emma of Normandy. They had a son named Harthacnut.

When Cnut died, Harthacnut became king of the Danish Empire, however, he lost England to Edward the confessor in 1042.

Adam tells that after Sygtrigg reigned a short time, during the tenure of Archbishop Hoger of Bremen ( 909-915 / 917 ), Harthacnut ( Danish: Hardeknud ), son of king Sweyn, came from " Northmannia ," the " land of the Northmen ," by which he may have meant Norway, Normandy, which had recently been colonized by Danish Vikings, or even northern Jutland.

Historians generally agree that Vurm ( English: worm or serpent ) is a German rendering of the Danish name Gorm, which allows for an interpretation that Harthacnut and Gorm were originally the same person.

Forming a political alliance with former Stiklestad peasant army leader Kalv Arnesson, he then proceeded to broker an agreement between the puppet king Magnus and the newly installed Danish ruler, Harthacnut, son of Cnut the Great.

After Cnut's death in 1035 the English throne fell to Harold Harefoot, his son by his first wife, while Harthacnut, his son by Emma, became king in Denmark.

Harthacnut told the Norman court that Edward should be made king if he himself had no sons.

Cnut died in 1035, and Harthacnut succeeded as king of Denmark.

The king allowed Godwin to escape punishment by bringing witnesses that he had acted on Harold's orders, but Godwin then gave Harthacnut a ship so richly decorated that it amounted to the wergild that Godwin would have had to pay if he had been found guilty.

The English had become used to the king ruling in council, with the advice of his chief men, but Harthacnut had ruled autocratically in Denmark and he was not willing to change, particularly as he did not fully trust the leading earls.

She had returned to England ( at least ) by 1036, while Emma's son Harthacnut was away in Denmark, at war with the Norwegian king Magnus I, and the Swedes under their king Anund Jacob.
