Eadgils

Eadgils, Adils, Aðils, Adillus, Aðísl at Uppsölum, Athisl, Athislus or Adhel was a semi-legendary king of Sweden, who is estimated to have lived during the 6th century.

Beowulf and Old Norse sources present him as the son of Ohthere and as belonging to the ruling Yngling (Scylfing) clan. These sources also deal with his war against Onela, which he won with foreign assistance: in Beowulf he gained the throne of Sweden by defeating his uncle Onela with Geatish help, and in two Scandinavian sources (Skáldskaparmál and Skjöldunga saga), he is also helped to defeat Onela in the Battle on the Ice of Lake Vänern, but with Danish help. However, Scandinavian sources mostly deal with his interaction with the legendary Danish king Hrólfr Kraki (Hroðulf), and Eadgils is mostly presented in a negative light as a rich and greedy king.
