Conrad said:What later historians have shown is that in the 12th and the 13th centuries, the nobility of Geatland was the driving force behind the centralization of Sweden. To a linguist, this does however not provide a satifying answer behind the name Svearike, (Sweorici in Beowulf).
We do not have historical sources that show where the Svear were located but we do have linguistic sources.
My personal theory is based on what I know about the history other countries, such as France, India and China. In these countries the ethnic name and the name of the country was carried by a "nobility". If we combine the traditional theory in which the Svear subjugated the Geats we may have had a Svealand nobility that took over the lands of the Geatish strongmen, and then we would have had a very typical development in which a foreign clan ruled a conquered territory.
This means that both the traditional theory and the modern theories may be right, and that our ancestors behaved like tribes all over the world.
The problem with historians is that like most of us, they usually only accept either or theories: Sweden was created either from Svealand or from Geatland.
Fair enough.
There seems to be a difference in how the administration of the two areas was set up though. One indication of that is from how the taxation developed, in Götaland it developed from the "gästning" (the king would go around visiting different places and stay there until there was no more food), in Svealand it developed from the "ledung" (the host of men and ships the king could call on for war). If 'nobility' from Svealand really replaced the ones in Götaland wouldn't they have brought with them the same way of doing things? It's possible that they wouldn't have, I'm just posing the question.
The name of Sweden in Scandinavian sources (even as young as Snorri) was 'Svitiod', isn't it possible that the use of 'Sverige' was taken over from Old English (Sweorici) via the english missionaries who were especially common in western Götaland? I know something similar to be the case with Denmark... the name was in use abroad before it first appeared on the Jelling rune stones (Tanmarkr) around 950 AD.
