Blot-Sven Regent of Sweden
- Born: Abt 1050, Sweden
- Marriage: Stenkilsdatter
Another name for Blot-Sven was Blot-Sweyn.
Blot-Sven (king 1084–1087) ousted his brother-in-law Ingold from Svealand, when he had refused to administer the sacrifices at the Temple at Uppsala, in ca 1080.
In 1087, Ingold travelled with his housecarls through Smalandia and Ostrogothia, riding both day and night, until he arrived in Sweden. Having arrived at Old Uppsala, he surrounded the hall of Blot-Sweyn, and set the hall on fire. When the king ran out, he was immediately slain. This is probably the date of the destruction of the Temple at Uppsala.
Blot-Sven was the last pagan king of Sweden and his fall marks the final victory of the Christian faith in Sweden. Some regard him as he progenitor or the House of Sverker.
House of Sverker:
After the extinction of the House of Stenkil and the coronation of Sverker I of Sweden in 1130, a civil war commenced. In the beginning, there were several pretenders, of whom Sverker I emerged as victorious, for a time. The antagonists in long run were finally the House of Sverker in Ostrogothia and the House of Erik in Uplandia, which alternated on the throne for several generations, until in 1220's, the Eric dynasty got the upper hand and the Sverker dynasty had gone extinct (at least in male line). As usual in medieval succession rivalries, the final outcome combined the blood of rival lines, as in 1250 Valdemar of the Folkungs (then a minor, his father Birger Jarl acting as Regent) ascended the throne, having inherited the Eric dynasty claim from Valdemar's mother (who was sister of Eric XI of Sweden, the last Eric-dynast) and some of the Sverker dynasty claim from Birger's mother (who was daughter of a younger son of Sverker I).
Blot-Sven married Stenkilsdatter, daughter of King Stenkil Ragnvaldsson of Sweden and Maria Anundsdatter. (Stenkilsdatter was born about 1050 in Sweden.)
