Little has survived of such battles in the Norse sagas, and later 11th century-13th century wars between Swedes and Geats, notably involving the Geatish clans House of Stenkil and House of Sverker, are referred to as Swedish civil wars.
The Norse sagas offer limited information about battles from that era, but later conflicts between Swedes and Geats in the 11th to 13th centuries, particularly those involving the House of Stenkil and House of Sverker, are referred to as Swedish civil wars.
