Sweyn II of Denmark

Sweyn Estridsson Ulfsson[a] (Old Norse: Sveinn Ástríðarson, Danish: Svend Estridsen; c. 1019 – 28 April 1076)[2][3] was King of Denmark (being Sweyn II) from 1047 until his death in 1076. He was the son of Ulf Thorgilsson and Estrid Svendsdatter, and the grandson of Sweyn Forkbeard through his mother's line. He was married at least two times, and fathered 20 children or more out of wedlock, including the five future kings Harald Hen, Canute the Saint, Oluf Hunger, Eric Evergood, and Niels.

He was courageous in battle, but did not have much success as a military commander.[4] His skeleton reveals that he was a tall, powerfully built man who walked with a limp.

Biography[edit]

Accession to the throne[edit]

Sweyn was born in England,[4] as the son of Ulf Thorgilsson and Estrid Svendsdatter, the latter of whom was the daughter of King Sweyn I Forkbeard and sister of Kings Harald II and Canute the Great. Sweyn grew up a military leader, and served under king Anund Jacob of Sweden for a time.[4] He pillaged the Elbe-Weser area in 1040, but was caught by the Archbishop of Hamburg-Bremen, who released him shortly thereafter.[5]


Svend was made a jarl under Danish king Harthacnut (the two were first cousins),[4] and led a campaign for him against Norway, but was beaten by Magnus I of Norway.[5] When Harthacnut died in 1042, Magnus claimed the Danish throne and made Svend the jarl of Jutland.[6] In 1043, Sweyn fought for Magnus at the Battle of Lyrskov Heath at Hedeby, near the present-day border of Denmark and Germany.[5] Sweyn won a great reputation at Lyrskov Heath, and had the Danish nobles crown him king in Viborg in Jutland.[6] He was defeated by Magnus on several occasions, and had to flee to Sweden. Eventually he managed to return and establish a foothold in Scania.[5]


The war between Magnus and Sweyn lasted until 1045, when Magnus' uncle Harald Hardrada returned to Norway from exile. Harald and Sweyn joined forces, and Magnus decided to share the Norwegian throne with Harald.[4] 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.[6] Upon hearing of Magnus' death Sweyn said, "Now so help me God, I shall never yield Denmark".[7]

Feud with Harald Hardrada[edit]

Harald, unwilling to relinquish Denmark, attacked Sweyn and fought a long war. Harald sacked Hedeby in 1050, and also sacked Aarhus.[5] 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.[7] Sweyn came close to losing his life at the naval Battle of Niså off the coast of Halland in 1062.[4] According to the sagas Harald urged Sweyn to meet him in a final and decisive battle at Elv in the spring of 1062.[8] 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.[9] 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.[10] This might be the aiding Norwegian chieftain that Saxo Grammaticus refers to, as turning the tide in Norwegian favour.[11] 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.[7] 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,[4] in exchange for Sweyn's recognition of Harald as Harald III of Norway.[6] Harald then sailed off to England to claim the crown of England, and was killed there.

Legacy[edit]

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 medieval one. A strengthened church in alliance with the land-owning noble families begin to pit their power against the royal family. The peasants were left to fend for themselves.[15]


Sweyn built a strong foundation for royal power through cooperation with the church. He completed the final partition of Denmark into dioceses by corresponding directly with the pope, bypassing the Archbishop of Hamburg-Bremen. During his reign hundreds of small wooden churches were built throughout the kingdom; many were rebuilt in stone in the 12th century.[5] Sweyn sought to create a Nordic Archbishopric under Danish rule, a feat which his son Eric I accomplished.[12]


Sweyn seems to have been able to read and write, and was described as an especially educated monarch by his personal friend Pope Gregory VII.[12] He is the source of much of our current knowledge about Denmark and Sweden in the 9th and 10th centuries, having told the story of his ancestry to historian Adam of Bremen around 1070.
