Burislev is mentioned in the regnal list appended to
Västgötalagen together with Kol: "[King Canute I] won Sweden by sword and killed King Karl, King Kol and King Burislev, had many fights in Sweden and was victorious in all". Otherwise, he appears in fewer medieval sources than his brother whose name occurs in several king-lists. According to annotations by the 17th-century scholar
Johannes Messenius, Kol fell in battle, but Burislev continued the struggle against Canute with some success. However, when he carelessly stayed at the mansion of
Bjälbo he was assaulted by Canute's troops and killed. Still later traditions have it that Kol and then Burislev were killed in battle at Blodåkrarna (the Blood Fields) close to Bjälbo, in 1169. Most probably, however, the struggle came to an end in 1172–73, since Canute reportedly reigned for 23 years after his victory. It has been speculated that Canute I married a sister of his antagonists Kol and Burislev whose name was
Cecilia, and to whom he was betrothed in c. 1160. This hypothesis is based on an annal entry which mentions a Princess Cecilia, mother of
Eric the Saint, as the sister of Kol and Ulf (Ubbe). Eric the Saint, it is argued, might be a mistake for
Eric X of Sweden, the son of Canute I. This hypothesis has been disputed, however. Though several sources affirm that Burislev actually was King of Sweden for a few years, the
Swedish Royal Court does not recognize him as such in its official list of rulers. == References ==
