The Battle of Sparrsätra, fought between the forces of King Eric XI of Sweden and rebels led by Holmger Knutsson, took place in 1247 near Enköping in Sweden. It occurred during a poorly documented period in Swedish history; as a result, many details are uncertain and conjectural. Although it was not the end of the Folkung rebellion, many scholars consider it to have marked the end of the old order, leading to the Uppland Swedes' loss of their semi-aristocratic status, and to the beginning of taxation by the King.
