King of Sweden. This founder of the Sweartgarian Dynasty of Swedish kings was a magnate of the first family of the Ostrogothland province, possibly the near descendant of an obscure King Eric (VIII) Goodyear (Erik Årsäll) a.k.a. Coal (Kol) and of Hacon Red, the so-called Blood Swain. His father probably was a major landowner called Wolf the Grain-Wealthy (Korn-Ubbe) and his year of birth here is an approximation. His dynasty vied for the throne with the competing Erican Dynasty, would fight it for the next hundred years, and then die out almost simultaneously. When the previous Steinchetellian Dynasty expired, Sweartgar ruled at least most of Sweden from around 1130, after the brief reigns of Reynold Knobhead and Magnus I. By 1134 he had gained the whole kingdom. He married two dowager Queens of Sweden in turn, Wolfhilda, widow of Ingi the Younger, and Richeza, of Magnus I. With Queen Woflhilda, he founded several monasteries and began building a cathedral at Old Upsala next to the ancient royal tumuli. The seat of the Roman church in Sweden had been moved there from Sigtuna. The future Pope Adrian IV, an Englishman, visited Sweden and attended a great church meeting in Linköping in 1152 without, however, being able to get a first Swedish archbishop appointed. Four years later, King Sweartgar I was assassinated on Christmas morning on his way to early mass at Ödeshög. December 25, 1156, thus became the first definite full date recorded in Swedish history. Queen Richeza survived Sweartgar having born him a son named Boleslaw for her father, a ruler of Poland. His children in the first marriage were Prince John, who was put to death by an angry mob after having abducted a noble maiden from a nunnery, plus the future King Carl I, Ingigarth who became Prioress of Vreta, Helen who married King Canute V of Denmark and (probably) a prince called Sonny Cisco (Sune Sik), maternal grandfather of Birger Jarl. Another son by an unknown liason, or possibly a brother, Coal, was involved with Boleslaw in a struggle for the throne after Carl's death. The body of Sweartgar I was probably laid to rest at first at a specially prepared Sweartgarian Chapel (Sverkerskapellet) where he was killed on the shore of Lake Vätter, and was moved much later to Alvastra.
