Halsten Stenkilsson (English exonym: Alstan;[1][2] Old Icelandic: Hallstein[3]) was King of Sweden from c. 1067 - 1070.
[5] In a scholia in the work of Adam of Bremen, he is reported to have been elected king after the violent death of two pretenders,[5] but took over a highly volatile situation.
[4] In the regnal list of the Westrogothic law, he is said to have been courteous and cheerful, and whenever a case was submitted to him, he judged fairly,[5][6] and this was why Sweden mourned his death.
[4][5][6] The Hervarar saga, which is one of the few sources about the kings of this time, has the following to tell: Hallsteinn hét sonr Steinkels konungs, bróðir Inga konungs, er konungr var með Inga konungi, bróður sínum.
Synir Hallsteins váru þeir Philippus ok Ingi, er konungdóm tóku í Svíþjóð eptir Inga konung gamla.
