John, Prince of Sweden (12th century)
|House of Sverker|
John (modern Swedish: Johan Sverkersson den äldre; in Old Icelandic sources called Jón jarl Sørkvisson), who died between 1150 and 1153, was the eldest son of King Sverker I of Sweden of Sweden and his queen Ulvhild Håkansdotter.
He appears to have abducted and had sexual intercourse with two high-born Danish women. These incidents caused a war in which the Danish king Sweyn III of Denmark intervened in Småland in 1153–54. By this time John had already been beaten to death by angry farmers.
We have no information about John's wife, but according to a medieval genealogy John must have been the father of the two subsequent contenders for the Swedish throne, Kol of Sweden and Boleslaw of Sweden, and another man named Ubbe. This has been accepted by some historians, such as Adolf Schück, and Lars O. Lagerqvist and Nils Åberg.
John also seems to have had a son called Knut, born around 1152, who died young and a daughter who in unnamed but may have been Cecilia Johansdotter of Sweden, consort to Canute I of Sweden. According to a seventeenth-century source, John might had had another son, called Alf, who died young and, like Burislev, was interred in Vreta Abbey.
