Sweden is a perfect contender for a 30-years scenario which can go hand in hand with reintroducing Religion again. If they wouldn't have that option in mind, they would have just named the Viking Civ Vikings, and not Denmark(-Norway).
They named it Denmark because they got smart and realized that the "vikings" weren't an organized group of people that could be represented with a single civilization. They were a lose collection of tribes and clans that terrorized Europe in the Middle Ages. Also, by naming the civ "Denmark", they could represent Denmark in its uncivilized "Viking Age" with the berserker unit, as well as its civilized, modern day self with the Norwegian ski infantry unit. Plus, it was the Danish vikings that conquered Britain, who's language formed the foundation for English. They were arguably the most important.
