The territories of the Swedes [Sviar , Suioni]- Yellow.
The Götar [Gauti , Geats] - Blue.
And the Gutar [ Gotlanders] - Green, placed on the modern Swedish map.
South of all these where the Dani (Danes).
However, these borders changed over time too and though at this time there where no Swedish or Danish nations there would be wars and conflicts between these groups for many hundred years ahead (even after the nations where formed).
Today, people living in Sweden see themselves as ethnic Swedes, but distinction between Swedes and Geats was mentioned as more than a name more or less until modern time (1500s) and the Swedes (as you might have guessed) dominated from rather early on.
