The Birkebeiner conflict was a civil war in Norway during the early 13th century, primarily between two factions: the Birkebeiners and the Baglers. The Birkebeiners supported the rightful heir to the throne, while the Baglers were loyal to a rival claimant. This conflict was marked by battles and political intrigue as both sides vied for control of the Norwegian crown. The name "Birkebeiner" comes from the term for the faction's supporters, who were known for wearing birch bark as a form of clothing. The conflict is significant in Norwegian history, as it shaped the future of the monarchy and influenced the country's political landscape for years to come.
