Svealand comes from the Viking, early middle age period I think, Svear was the clans living in and around mälardalen, or north east of the big lakes, Götar was the ones who had their main areas in what is now called Västgötaslätten - Skara, Skövde etc.
In old english they were known as Sveons and Geatas as far as I know, at least if you go by Beowulf, not that beowulf is the best place to try and find historical facts, but still...
Think they are mentioned in Tacitus book Germania as well form around year 100.
Basically you need to stop liking the name Svealand, it's never been a name for our entire country, just the worst part lol! ;P
Yellow-Svear
Blue-Götar
