The Battle of Stainmore was a conflict between Eric Bloodaxe and opponents possibly led by Oswulf I of Bamburgh or a Maccus son of Olaf. Eric had previously been invited by the Northumbrians to rule as their king and had come into conflict with King Eadred of England, on whose behalf Maccus may have been acting. Eric's death at Stainmore led to the end of the independence of Scandinavian York, with Oswulf becoming earl of Northumbria and ruling on behalf of Eadred.
