History of Denmark in 8th century
In the 8th century CE there are several kings of both mythical and quasi-historical carachter. The Anglo-Saxon epic poem Beowulf tells that Hroar was king of the Danes. The poem was written in the 8th century, but there is no clue to when the alledged events of the poem took place. A peculiar note to this is that Hroar actually was king, he was just king of the Herules; a sub-group of the Gothic tribes of central- and eastern Europe. Interestingly it is said that the heathen Herules wandered back north to their fellow believers when the Goths were christianised (Jordane).
Saxo lists a king Roar, son of Dan, who alledgedly founded the city of Roskilde, the capital of Denmark through a longer period in the Middle Ages, until Bishop Absalon founded Copenhagen, at the time only known as 'Hafn' (Habor).
Ongendus/Angantyr is also said to have ruled in this century, as well as Sigfrid.
