Before he became a White Walker, the Night King was a First Man that was captured by Children of the Forest, Leaf among them. Leaf pressed a dragonglass dagger into his chest, causing his eyes to turn blue and turning him into the first of the White Walkers. The Children of the Forest created the White Walkers to defend themselves when Westeros was invaded by the First Men, who were cutting their sacred trees and slaughtering them.

Nice! If only they included this fact into the show. If it is, I would love to know which episode.

Yes it was on the show, season 6. It was one of the visions of Bran and one of the forest kids it to him. Same episode when they attacked and Hodor happened.
