The battle significantly strengthened the separatist cause, making Kettil Karlsson effective ruler of most of central Sweden and prompting the return of King Charles Canutesson, who was hailed as king by the separatists. However, a conflict between Charles and the bishops, Jöns Bengtsson and Kettil Karlsson, soon arose after Jöns Bengtsson's arrival in Stockholm, with the bishops getting the upper hand, excommunicating and again deposing the King. Kettil Karlsson ruled as Regent of Sweden for half a year in 1465 before dying from bubonic plague.Nordisk Familjebok: Vasaätten. Kettil Karlsson. , Uggleupplagan, Band 31, 1921, pp. 767–768 Jöns Bengtsson became Regent upon Kettil Karlsson's death but was driven to retire by the Privy Council, replacing him as Regent with Charles' follower Erik Axelsson Tott. Charles Canutesson would eventually return to rule Sweden a third time in 1467 until his death in 1470. The Battle of Brunkeberg in 1471, where the separatists were commanded by Regent Sten Sture the Elder, one of the separatist leaders at the Battle of Haraker, would eventually give the separatists the upper hand in Swedish politics during most of the final decades of the 15th century.
