Yeah but I'm a Swede and even I thought those regions were named long after Rome, in tribute to Roman history. Claiming the origins of the infamous Goths just because of their accomplishments in the south.
Because Swedish history before 1000AD is very murky.
You did not find it weird that Beowulf identified as a geat?
Never read it, but also, wasn't it written like hundreds of years after? I thought the oldest written stories we had were Snorres and the Icelandic sagas.
So the 5th and 6th centuries are still very much guesswork when it comes to scandinavian history.
I just always assumed that the legend of Rome was powerful enough for swedes to claim the Goths. But it makes sense that it's based on fact.
