The name of this king is only known from Adam's work
Gesta Hammaburgensis ecclesiae pontificum from c. 1075. The
Archbishop of Hamburg-Bremen,
Unni, was able to arrange church matters in
Denmark after the defeat of the
Danes at the hands of King
Henry the Fowler of
Germany in 934. From Denmark he proceeded to the Swedish trading port
Birka in 935 or 936. Referring to information from the Danish King
Sweyn Estridsen, Adam states that the Swedes at this time were ruled by a certain Ring and his sons Erik and Emund. Adam finds it likely that Unni approached these heathen kings and obtained permission to propagate Christianity, which by this time was long forgotten in the region. After his mission was over, Unni prepared to return but fell ill and died in Birka in 936. Later on Adam mentions an
Emund Eriksson as ruling in Sweden at the height of
Harald Bluetooth's reign in Denmark (around the 970s). From his name he appears to have been a son of Erik Ringsson. ==Place in the Swedish king list==
