the Victorious, Olof Skötkonung, Anund Jacob and Emund the Old. The answer to the question regarding who was Sweden's first king depends on what is meant with "Sweden"; the earliest king reliably known to have ruled both Svealand and Götaland, the core territories of the country, was Olof Skötkonung, who is also listed first in most medieval Swedish king lists. Legendary kings Hervarar saga ok Heiðreks The Hervarar saga ok Heiðreks has in some versions an addition which gives a regnal list of Sweden following the death of Ingjald Illråde, the last king of the Yngling dynasty. Sweden was first ruled by Ivar Vidfamne, then Harald Wartooth and his son Eysteinn Beli, before Björn Ironside conquered Sweden. He founded the House of Munsö, and the saga then follows his descendants until Philip of Sweden. The following chart maps the descendants of Björn Ironside according to the saga: Vita Ansgari and Adam of Bremen Rimbert, who travelled with the bishop Ansgar to Sweden as a missionary in the 9th century, wrote about several kings in Vita Ansgari. As Rimbert was a contemporary to the kings he writes about, the Vita is seen as a believable source. Adam of Bremen alludes to the kings mentioned by Rimbert and expands the list of kings to cover the following centuries. However, the distance in time is greater, and he is thus seen as a weaker source for the time before Eric the Victorious. Though no genealogical information is provided by either which confidently connects the kings they mention with Eric the Victorious and his descendants, they are typically assumed to have been part of the same royal dynasty. Attempts have been made to harmonize Rimbert's and Adam of Bremen's kings with the kings mentioned in the sagas (whose existence is otherwise seen as contradicted by their writings), but due to a lack of documented evidence, such attempts have to be considered unreliable and unverifiable. Kings from the Vita Björn, who reigned 829 when Ansgar first visited Sweden at the important port-settlement of Birka. Björn was reportedly friendly to the missionaries but chose not to convert to Christianity (although one of his chief councilors, Hergeir, did). Anund, who is not mentioned as ruling over Birka (possibly ruling somewhere else in Sweden), having been driven from Sweden and taken refuge among the Danes. Anund promised Birka to the Danes as a reward for helping him gain
