Im sorry.. I dont mean to do the viking credit list. But by historic facts..
It was danish kings that became kings of England, was granted the right to rule England even by the pope and thus granted the Normas their right. the last saxon king Harold. and his father even and the king before him where all born of danish. harold is even connected to the know royal family of Denmark. the oldest royal family in the world.
Denmark had over 60% of the viking pop. because of its location. and much of the power came from there because of that. more land more food more people.
It was called Daneland. Danegaeld.Dane axe. and so on for a reason.
But, the language was in it self not danish, norwegian or swedish. but old norse. a language commen in scandinavia. where the scandic culture was. what today is called viking. (wasnt at the time) English is infact not really a old and certain language. English is a combined language of other language, also why for many it more easy to learn.
And then, that is what history tell. that is the fact of that history.
And im not danish. that is not why I say that.
