It may not be evolution, it may just be a few families, too inbreed, who happen to have a higher rate of light skin, light hair, light eyes. Even if they accomplish a tenth of what Ginges Khan did, maybe even just a hundredth, the idea that light = elite was born. Thus low class families who happen to get a light kid will spoil them rotten, at the expense of the swarthy ones, in hope to get a better social standing for them and their descendants. In turn, they will often get the best spouse as these elite look alike are highly sought after. And the elite, who probably wasn't so light to begin with would do the same to keep ahead, until a few thousand years later, light skin, hair and eyes become the new normal.
You just described a way in which evolution can occur. We don't know how the evolution happened but it did.
