2 - Not completely acurate as I'm portuguese and we had two diferent clans of vikings ruling over us. The wiped the romans and kept there for 300years give or take
"Some sort of invented name" is spot on. :-)
I've never seen the Vikings at the school.
Malta for the win!
So just who are we defining as Vikings? Vikings are those Scandinavians that travelled WESTWARDS from (mainly) Denmark and Norway. Varangians are those Scandinavians who travelled mostly EASTWARDS AND SOUTHWARDS from (mostly) Sweden. I am not certain that the term Viking or Varangian has any basis in historical nomenclature. I did however get most of the answers - although not Malta
The Northmen who settled in Byzantium were definitely Varangians and not Vikings cf Varangian Guard.
Still an interesting one
Based on DNA, the Nordics are the homelands of the Vikings. If you go by the common haplotype, West Finland has the most of it, today, right behind being Norway, Sweden and Denmark. Close behind the Baltic states. A noticeable amount elsewhere in Europe esp. West/more Northern parts. Then again, there are many traces of Vikings picking up spouses from wherever (e.g. see Iceland where there are many genetic markers from Scotland and Ireland), settling here and there, mixing with locals, even continuing all the way to Georgia to settle, Canada to attempt and many other places incl. in Islamic Levant, North Africa... and then many Vikings simply disappearing from history due to who knows what reason, maybe just settling in wherever you might find blue eyes these days.
So, in the lack of full evidence: you define who is a Viking.
