Sverker I or Sverker the Elder was King of Sweden from about 1132 until his murder. Of non-royal descent, he founded the House of Sverker, the rulers of which alternated with the rival House of Eric over the next century.

Magnus the Strong, also known as Magnus Nilsson, was a Danish duke who ruled Gothenland 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".
