Magnus Minniskiöld was a medieval Swedish Lawspeaker from the House of Bjelbo.
Background
His earliest known ancestor is thought to be Folke the Fat, a powerful Swedish leader of the early 12th century, who married Ingegerd Knudsdatter daughter of Canute IV of Denmark, becoming one of the first magnates of the Kingdom of Denmark. He was the son of Bengt Snivil, and younger brother of the Riksjarl Birger Brosa.
Career
He is commonly believed to have been killed in battle, most likely in the Battle of Lena in 1208, or at the Battle of Gestilren in 1210. He lived at the family estate Bjälbo, in the current Mjölby municipality, Östergötland, Sweden. He is mentioned in two contemporary diplomas (Doctor of Science 70, 116), as the brother of Birger Brosa, as well as by King Magnus Birgersson, who in a letter in 1280 called him "grandfader".
Nothing is known about his supposed first wife.
Sune Sik, if he existed, was a younger son of King Sverker I of Sweden. Although as the younger brother of Birger Brosa, Magnus was not the head of the powerful family, it his clear that he was actively involved in the fight between Sverker II of Sweden of the House of Sverker and Eric X of Sweden of the House of Eric for the Swedish crown, which was fought for over three main battles: In the Battle of Älgarås, (now a place in the Swedish community Töreboda in Västergötland) in November 1205 - in the Sverker II defeated Erik Knutsson.
Lastly, in the Battle of Gestilren (perhaps in Enköping in Uppland) on July 17, 1210, in which the displaced King Sverker II, with a Danish army, attempted to regain his throne, but was defeated and died in the battle. Though he was most likely killed in the 1208 Battle of Lena, he may not have been killed until the Battle of Gestilren in 1210.
