Eric IX, (Swedish: Erik Jedvardsson; Erik den helige; Sankt Erik; d. 18 May 1160) also called Eric the Holy, Saint Eric, and Eric the Lawgiver, was a Swedish king in the 12th century, 1156–1160. The Roman Martyrology of the Catholic Church names him as a saint memorialized on 18 May. He was the founder of the House of Eric, which ruled Sweden with interruptions from c. 1156 to 1250. Background As later kings from the House of Eric were consistently buried at Varnhem Abbey near Skara in Västergötland, Eric's family is considered to have Geatish roots like other medieval ruling houses in Sweden. Osteological investigations of Eric's remains suggest that he may have lived the last 10–15 years of his life in Västergötland rather than in Uppland where he died. On the other hand, the only manor he is known to have possessed is situated in Västmanland in Svealand. Eriksberg in central Västergötland has been suggested as the original family manor. Eric had a brother whose name began with a "J"; this brother has been identified with a Joar Jedvardsson. This in turn fits with King Sverre's Saga, which refers to "Eirik the Saint, son of Jatvard". Late medieval Swedish tradition likewise knows the king by the name Eric Jedvardsson. The name of the father, Jedvard (Edward), is not Scandinavian and may point to English missionary influence. According to 14th-century tradition, Eric's mother was Cecilia, a daughter of King Blot-Sweyn. This information is disputed, however. Legend The only full account of Eric's life is a hagiographic legend dating from the late 13th century. The historicity of the legend has been much-discussed by Swedish historians. It tells that Eric was of royal blood and was unanimously chosen king of Sweden when there was a vacancy of the kingship. It also states that Eric reigned for ten years, which would put the beginning of his reign in c. 1150. If this is correct he would have been a rival king to Sverker I, who had ascended the throne in c. 1132 and was murdered in 1156. At any rate it is assumed that Eric was recognized in most provinces after 1156. While his paternity is obscure, there is good evidence that he strengthened his claims to the throne by marriage to the Danish princess Christina Björnsdotter, a granddaughter of King Inge the Elder. His realm did not include Östergötland, where Sverker's son
