Also, the nords, as far as I know, didn't invade a country that wasn't theirs in the first place and slaughtered the native people, to bring 'civilisation' to the lands.
But I could be wrong.
Actually they Nords did invade a country that wasn't theirs in the first place and slaughtered the native people.
The Nords originally came from Atmora, an icy wasteland far far to the north. Then, the Nords went south to Skyrim, where the Falmer (snow elves) lived.
The Falmer eventually felt threatened and attacked. The Nords were driven out at first, but then returned with massive armies and slaughtered the Falmer civlization once and for all.
Eventually, some Nords went further south in Tamriel, and slowly became other races of men.
That's what I think I know about the Nords history.
