The Age of the Sturlungs was a period of internal conflict in 13th-century Iceland, driven by rivalry among powerful chieftain families. The conflict weakened the Icelandic Commonwealth and is closely connected to the changes that led to the Old Covenant and submission to the Norwegian crown in 1262–1264.
The period is central to understanding Icelandic political development and can be explored in the wider context of the history of the Althing and medieval power structures.
