Eric the Victorious was a Swedish monarch as of around 970. Although there were earlier Swedish kings, he is the first Swedish king in a consecutive regnal succession, who is attested in sources independent of each other, and consequently Sweden's list of rulers usually begins with him. His son Olof Skötkonung, however, is considered the first ruler documented to definitely have been accepted both by the original Swedes around Lake Mälaren and by the Geats around Lake Vättern. Adam of Bremen reports a king named Emund Eriksson before Eric, but it is not known whether he was Eric's father. The Norse sagas' accounts of a Björn Eriksson are considered unreliable.

Olof Skötkonung, sometimes stylized as Olaf the Swede, was King of Sweden, son of Eric the Victorious and, according to Icelandic sources, Sigrid the Haughty. He succeeded his father in c. 995. He stands at the threshold of recorded history, since he is the first Swedish ruler about whom there is substantial knowledge. He is regarded as the first king known to have ruled both the Swedes and the Geats. In Sweden, the reign of king Olov Skötkonung is considered to be the transition from the Viking age to the Middle Ages, he was the first Christian king of the Swedes, who ruled central Sweden. Norse beliefs persisted in parts of Sweden until the 12–13th century.
