The real source of the feuding that tore the Mongol steppe apart was women, which is why Genghis Khan's first law outlawed kidnapping and selling them.

Later, Genghis Khan will realize once he becomes Chinggis Khan, he will realize that the true source of most of the feuding on the steppe is over women. And later he will outlaw the kidnapping of women and the sale of women, in part not only because of what had happened to his mother, but what happened to him next in his life.
