returned to Norway from exile. Harald and Sweyn joined forces, and Magnus decided to share the Norwegian throne with Harald.
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.
Upon hearing of Magnus' death Sweyn said, "Now so help me God, I shall never yield Denmark".

Feud with Harald Hardrada

Hedeby in 1050, and also sacked

.
Sweyn almost captured Harald in 1050, when Harald attacked the coast of Jutland and loaded his ships with goods and captives. Sweyn's flotilla caught up with the Norwegians and Harald ordered his men to throw out the captured goods, thinking the Danes would stop to get the goods. Sweyn ordered his men to leave the goods and go after Harald. Harald then ordered his men to throw the captives overboard. For them Sweyn was willing to let Harald slip away.
Sweyn came close to losing his life at the naval
Battle of Niså off the coast of
Halland

in 1062.
According to the sagas Harald urged Sweyn to meet him in a final and decisive battle at Elv in the spring of 1062. When Sweyn and the Danish army did not show up, Harald sent home a large part of his army, only keeping the more professional warriors in his fleet. When Sweyn finally came to meet Harald, his fleet numbered 300 ships to Harald's 150. The fleets met at night and the battle lasted until morning, when the Danes started to flee. In the sagas the Norwegian victory is largely credited to earl Haakon Ivarsson, who disengaged his ships from the Norwegian flanks and started attacking the weakened ships on the Danish flanks. This might be the aiding Norwegian chieftain that Saxo Grammaticus refers to, as turning the tide in Norwegian favour. Sweyn managed to escape the battle, reached land and stopped at the house of a peasant to ask for something to eat. "What was the terrible rumbling in the night?" she asked. "Didn't you know the two kings were fighting all night?" asked one of Sweyn's men. "Who won, then?" the woman asked. "Norwegians," came the reply. "It's a shame on us, for a king we already have. He limps and is timid." "No," King Sweyn explained, "Timid the king of the Danes is assuredly not," defended another of the king's men, "but luck isn't with him and he lacks a victory." The housecarl brought the men water and a towel to wash themselves. As the king was drying his hands, the woman tore the cloth from him, "You should be ashamed of yourself for using the whole towel for yourself," she scolded. "The day will come when I will have your permission to use the whole cloth," was the king's comment. Her husband gave the king a horse and Sweyn continued on his way to Zealand.
Some time later the peasant was called to Zealand and given lands there for his service to the king, but his wife had to remain behind in Halland.
Sweyn had a reputation for generosity and kindness that helped him on several occasions to win the trust of his people. Harald relinquished his claims to Denmark in 1064,
in exchange for Sweyn's recognition of Harald as
Harald III of Norway.
Harald then sailed off to England to claim the
crown of England, and was killed
there.
Consolidation of power

Sweyn's connection to the Danish kings was his mother Estrid Svendsdatter, and he took the
matronymic surname Estridsson after her, emphasizing his link to the Danish royal house.
He also minted his own coins.
Sweyn sought to consolidate his power through links to the church as well as foreign powers, and actively sought the friendship of the popes.
He wanted his eldest son
Knud Magnus crowned by the Pope, but Knud died on the journey to Rome. He also unsuccessfully pressed for
Harald Bluetooth

. Sweyn failed another attempt in 1074/1075.
Relationship with the church
Sweyn feared that Archbishop
Adalbert of Hamburg would fill the upper ranks of Denmark's churches with Germans, so he brought Anglo-Danes over from England to keep the Danish church independent. Under the influence of Sweyn,
Denmark was divided into eight dioceses around 1060. He set the dioceses up by donating large tracts of land, with the
Diocese of Roskilde being the most-favoured one, as he had a good relationship with
Bishop Vilhelm.
When Archbishop Adalbert died in 1072, Sweyn was able to deal directly with the

so they could converse with the rest of Europe on equal terms.
Adam of Bremen travelled to meet this learned king and came away with greater respect for the king's patience and wisdom. Sweyn encouraged the building of churches all over Denmark, and Adam of Bremen was astounded that there were 300 churches in
Scania alone, more than in all the other countries of the north put together.
Death
King Sweyn died at the royal estate Søderup, west of
Åbenrå at the
Little Belt strait. The Danish chronicles inaccurately date his death to 1074, but it is known that he received and answered letters in 1075 and died in 1076.

Bishop Vilhelm (who was the actual person who died in 1074). Later he was called the "father of kings" because five of his fifteen sons became kings of Denmark.
He was the last Viking ruler of Denmark and an ancestor of all subsequent Danish kings.

accessed July 2018. The remains of other Danish kings are also entombed in Roskilde Cathedral. According to the saga, Sweyn's mother was entombed inside a pillar across from the chapel. However, analysis of mitochondrial DNA proved that this person was not the king's mother, as his
mtDNA indicated Haplogroup H, HVR1 7028C.
Legacy
One of the legacies of King Sweyn was a fundamental change in Danish society which had been based on whether a person was free or a bondsman. Sweyn is often considered to be Denmark's last Viking king as well as the first

Sweyn seems to have been able to read and write, and was described as an especially educated monarch by his personal friend

Family
Sweyn's first marriage was to
Gyda of Sweden, daughter of king Anund Jacob of Sweden. His second marriage, in 1050, was to
Gunnhildr Sveinsdóttir, the stepmother of Gyda. The Archbishop of Hamburg-Bremen ordered that the union be dissolved,
which was effectuated by
Pope Leo IX.
[Svend 2. Estridsen](_blank)
at Gyldendal Åbne Encyklopædi According to
Adam of Bremen, Sweyn had a certain "Tora" at his court. Historian
Sture Bolin argues that this "Tora" is actually
Tora Torbergsdatter, the mother of king
Olaf III of Norway, linking this to a passage about a king marrying the mother of a king named Olof.
[Sture Bolin, "Kring Mäster Adams text", ''Scandia'' 4, 1932.] He took one mistress after another during his life. Sweyn fathered at least 20 children, of whom only one was born in wedlock.
