Mythical kings of Sweden

The legendary kings of Sweden are the Swedish mythological kings who preceded Eric the Victorious, according to sources such as the Norse Sagas, Beowulf, Rimbert, Adam of Bremen and Saxo Grammaticus, but who are of disputed historicity because the sources are more or less unreliable, and sometimes contradictory. They are called sagokonungar or sagokungar in Swedish, meaning "Saga kings" according to the etymology given by SAOB.

In sources such as Heimskringla and Ynglinga saga there appear early Swedish kings who belong in the domain of mythology. From about the 6th century, these kings are gradually succeeded by semi-legendary kings with at least partial claim to historicity, who were all depicted as descendents of the House of Ynglings/Scylfings, either in direct royal line, or through the House of Ragnar Lodbrok and the house of Skjöldung (Scylding).

A historical basis of some of the mythological kings was one of the last of Thor Heyerdahl's archeo-anthropological theories, as in The Search for Odin. Such suggestions are generally considered speculative, not scientific, but while there is no historiographical tradition that would confirm the historicity of Swedish kings prior to the 6th century, it is safe to assume that the Suiones, as a tribe mentioned by Tacitus in the 1st century AD, did have kings (Common Germanic *kuningaz) during the prehistoric period.
