Björn (Swedish king 829)

Björn (Old Norse: Bjǫrn) was a Swedish monarch or local ruler who ruled over Birka, an important port town, and possibly Uppsala, an important early Swedish political center, around the year 829. His existence is attested by the nearly contemporary account Vita Ansgari, written by the missionary Rimbert, who visited Sweden alongside Ansgar in c.  852. He is in fact the first Swedish figure referred as king who is known from a reasonably reliable source. Older Swedish historiography often identified the king with the legendary figure Björn at Haugi, who was supposedly a Swedish ruler in the generation before the youth of Harald Finehair of Norway. This identification is however considered unverifiable, since Björn at Haugi may have actually been a Norwegian local ruler who was later constructed as a Swedish king. Although the genealogy of early Swedish local rulers is not known, Björn is assumed to have belonged to the House of Munsö, which would later produce Eric the Victorious, generally considered to be Sweden's first king. The royal names attested in the ninth century, namely, also occur among the kings and princes in the late Viking age, perhaps suggesting a genealogical continuity.
