Magnus the Strong

Magnus the Strong (c. 1106 – 4 June 1134), also known as Magnus Nilsson (Danish: Magnus Nielsen/Nielssøn), was a Danish duke who ruled Götaland in southern Sweden from the 1120s to c. 1132. It is disputed whether he was elected king by the Swedes, but he is nevertheless sometimes found in the modern list of Swedish monarchs as Magnus I. Snorri Sturlason gives him the epithet "Strong".

He was also briefly co-king of Denmark from 15 April 1134 and until his death.
