However, Æthelred returned as king after Sweyn died in 1014.

The English king was forced into exile, and in late 1013 Sweyn became King of England, though he died early in 1014, and the former king was brought out of exile to challenge his son.

Within a few weeks, however, Sweyn died and Æthelred was called back to England by the witan.

In 1013 Æthelred sent Emma and her children to her brother in Normandy to escape Sweyn's invasion, and soon followed himself, but they were able to return when Sweyn died in February 1014.

Sweyn died in February 1014, and leading Englishmen invited Æthelred back on condition that he promised to rule ' more justly ' than before.

To complicate the matter, Heimskringla and other Sagas also have Sweyn marrying Eric's widow, but she is distinctly another person in these texts, by name of Sigrid the Haughty, whom Sweyn only marries after Gunhild, the Slavic princess who bore Cnut, has died.

In 1042 Harthacnut died while in England, and Magnus also became King of Denmark, in spite of a claim by Cnut's nephew Sweyn Estridsen, whom Harthacnut had left in control of Denmark when he went to England, and who had some support.

In 1047 Magnus died, having stated on his deathbed that his kingdom would be divided: Harald would get the throne of Norway, while Sweyn would be king of Denmark.

When Archbishop Adalbert died in 1072, Sweyn was able to deal directly with the Holy See.

King Sweyn died at his farm, Søderup, near Urnehoved Tingsted, near the town of Åbenrå.

When Sweyn died, Canute's brother Harald III was elected King, and as Canute went into exile in Sweden, he was possibly involved in the active opposition to Harald.

Tilsted stayed loyal to Sweyn Forkbeard and died in 1013, after having sailed up the rivers Humber and Trent with Sweyn Forkbeard and his son Knut ( Canute ), for Sweyn to be accepted as king of the Danelaw.

When Sweyn died, his elder son Harald Svendsen became King Denmark as England's former king Ethelred reclaimed it.

The Danes attacked and prevailed in 1013 under their King Sweyn ( or Sveyn ), who died in 1014.

Sweyn Forkbeard, the first Danish King of England, died a few weeks after his English opponent Ethelred the Unready had fled, so it is probable that he never properly took control of Cornwall.

* February 3 – Sweyn I Haraldsson Forkbeard, king of Denmark

Sweyn I Forkbeard ( Old Norse: Sveinn Tjúguskegg ; c. 960 − 3 February 1014 ) was king of Denmark and England, as well as parts of Norway.

* Sweyn I of Denmark ( d. 1014 )

* Sweyn Forkbeard ruled both Norway and Denmark from 999 to 1014.

This period of the English monarchy is known as the Saxon period, though their rule was often contested, notably by the Danelaw and later by the Danish king Sweyn Forkbeard who claimed the throne from 1013 to 1014, during the reign of Æthelred the Unready.

Soon, however, Sweyn accepted a further payment of Danegeld from William and returned home.

However, after capturing York, Sweyn accepted a payment from William to desert Edgar, who then returned into exile in Scotland.

That same year, as Ealdred was returning to England he met Sweyn, a son of Godwin, Earl of Wessex, and probably absolved Sweyn for having abducted the abbess of Leominster Abbey in 1046.

Mieszko decided on the alliance with Sweden probably in order to help protect his possessions in Pomerania from the Danish King Harald I and his son Sweyn.

Even though Gospatric and Siward's son Waltheof submitted by the end of the year, the arrival of a Danish army under Sweyn Estridsson seemed to ensure that William's position remained weak.

A son of Sweyn Forkbeard, and grandson of Harold Bluetooth, he was a member of the dynasty that was key to the unification and Christianisation of Denmark.

* Sweyn Knutsson, son of Canute the Great

Harold was a son of Godwin, the powerful Earl of Wessex, and his wife Gytha Thorkelsdóttir, whose supposed brother Ulf Jarl was the son-in-law of Sweyn I and the father of Sweyn II of Denmark.

During his childhood aliens were the target of Viking raids and invasions under Sweyn Forkbeard and his son, Cnut.

In 1043 Godwin's eldest son Sweyn was appointed to an earldom in the south-west midlands, and on 23 January 1045 Edward married Godwin's daughter Edith.

Beorn's elder brother, Sweyn of Denmark " submitted himself to Edward as a son ", hoping for his help in his battle with Magnus for control of Denmark, but in 1047 Edward rejected Godwin's demand that he send aid to Sweyn, and it was only Magnus's death in October that saved England from attack and allowed Sweyn to take the Danish throne.

Sweyn and Harold called up their own vassals, but neither side wanted a fight, and Godwin and Sweyn appear to have each given a son as hostage, who were sent to Normandy.

According to Adam of Bremen, an 11th-century historian, Harald's son Sweyn was baptised Otto, in tribute to the German king Otto I, who was the first Holy Roman Emperor.

In some of the old sources, such as the Jómsvíkinga saga, Sweyn appears as an illegitimate son of Harald Bluetooth, raised by the legendary Jomsviking and jarl of Jomsborg, Palnatoke.

Sweyn is also depicted as a rebellious son, who led an uprising against his father in 987, and chased him out of the court, forcing him to abandon his kingdom.

Cnut was a son of the Danish king Sweyn Forkbeard, and the heir to a line of Scandinavian rulers central to the unification of Denmark.

Some sources state that his son Sweyn forcibly deposed him as King.

Adam of Bremen's claim regarding Otto I and Harald appears to have been inspired by an attempt to manufacture a historical reason for the archbishops of Hamburg-Bremen to claim jurisdiction over Denmark ( and thus the rest of Scandinavia ); in the 1070s, the Danish King was in Rome asking for Denmark to have its own arch-bishop, and Adam's account of Harald's supposed conversion ( and baptism of both him and his " little son " Sweyn, with Otto serving as Sweyn's godfather ) is followed by the unambiguous claim that " At that time Denmark on this side of the sea, which is called Jutland by the inhabitants, was divided into three dioceses and subjected to the bishopric of Hamburg.

This defensive role is highlighted by the use of the bridge in 1016 as a defence against King Sweyn and his son King Cnut by Ethelred the Unready and again, in 1066, against King William the Conqueror.

In retaliation for the St. Brice's Day massacre of Danes in England, the son of Harald, Sweyn Forkbeard mounted a series of wars of conquest against England.
