Eric X of Sweden

Eric X (Erik Knutsson, c. 1180–1216), son of Canute I, claimed the Swedish throne against Sverker Karlsson. Three brothers fell at Älgarås in 1205; Eric fled to Norway, returned in 1208 and defeated Sverker at Lena, then slew him at Gestilren in July 1210.

Later that year he married Rikissa, sister of Valdemar II of Denmark, and in November became the first Swedish king known to be crowned. He died suddenly on Visingsö on 10 April 1216; his posthumous son later ruled as Eric XI.
