'Blot-Sven' (, "Sweyn the Sacrificer") was a Swedish king c. 1080^[2], who replaced his Christian brother-in-law Inge as King of Sweden, when Inge had refused to administer the blóts (pagan sacrifices) at the Temple at Uppsala. There is no mention of Sweyn in the regnal list of the ''Westrogothic law'', which suggests that his rule did not reach Västergötland.²

Becoming king

The earliest source that deals with Blot-Sweyn's coming to power is the Icelandic legendary saga ''Hervarar saga'':
However, Inge did not permit the people to follow the old ways, unlike his father Stenkil. The Swedes reacted strongly and asked Inge to either comply with the old traditions or abdicate. When Inge proclaimed that he would not abandon the true faith, the people pelted him with stones and chased him away. This was the opportunity for Sweyn to assume power, and the account provided by ''Hervarar saga'' concerning his inauguration contains a rare description of the ancient Indo-European ritual of horse sacrifice:

Legend of Saint Eskil

The later ''Legend of Saint Eskil'' tells that Inge was chased away from the kingdom. They then elected an idolator for king by the name Sweyn, an unworthy man and with reason called ''Blood-Sweyn''. He had this name because he made the people drink blood from bulls that had been sacrificed to the false gods, and he ate the sacrificial meat. The infidels assembled around their king in Strängnäs, where they butchered oxen and sheep, and gave offerings to their gods. They had a great banquet in honour of the king and the false gods. The English bishop Eskil then appeared and tried to convert the pagans to Christianity. They would not listen, however. Eskil prayed, and God sent thunder, hail, snow and rain destroying the sacrificial altar and beasts of sacrifice. Not a single drop fell on the bishop. The pagans were not impressed and furiously, they attacked Eskil. A diviner named Spåbodde hit him on the head with a stone, while another man crushed his head with an axe. Some chieftains dragged the dying martyr to the king saying that Eskil had used magic arts to control the weather. As soon as the unrightful king had sentenced Eskil to death, he was taken to the valley where the monastery later was founded, and he was stoned to death^[3]
This legend is, however, considered to be a later invention by the Church as more reliable sources date Eskil's death to c. 1016, several generations before Blot-Sweyn³.

How Sweyn was killed

According to ''Hervarar saga'', Sweyn's rule was not to last. Before long, the Christian Inge decided to kill the Pagan Sweyn in a less than honourable way:
A similar account also appears in the ''Orkneyinga saga'', but in this account, Sweyn stays indoors and is burnt to death:

Succession

It is possible that Ingi was not immediately accepted by the stubbornly pagan Swedes of Uppland. The 13th century historian Snorri Sturlusson wrote in the ''Heimskringla'' that Blót-Sweyn had a pagan successor who continued the sacrifices (Eirik Arsale):
Blot-Sweyn is believed to have been the father of Eric of Good Harvests (Eirik Arsale)^[4]. This Eric is mentioned by a plausible source as the father of Sverker the Elder^4[5], and so Blot-Sweyn could be the progenitor of the House of Sverker.
