In this particular case, you will have to find a Scandinavian tribe that was sufficiently unified in or around 272 B.C., and possessed the military might and political acumen for extensive expansion.
Well, they did attack the Roman empire a few times. How many people in that time period actually "ATTACKED" Rome??? (as in starting a war with Rome, NOT being invading them ESPECIALLY A BARBARIAN ONE AT THAT) They wanted land, they settled lots of land in Germania, and Cezh; mostly the northern part of Germania where there home land was close too. And attacked Rome on its northern front ( ITALY AT THIS TIME). Not sure if they managed to stay there, and if they did it wasn't for a long time. But that is simply history...

That in my opinion is one helluva contender.
