As an incentive for absolute obedience and following his rule of law, the Yassa code, Temüjin promised civilians and soldiers wealth from future possible war spoils. As he defeated rival tribes, he did not drive away enemy soldiers and abandon the rest. Instead, he took the conquered tribe under his protection and integrated its members into his own tribe. He would even have his mother adopt orphans from the conquered tribe, bringing them into his family. These political innovations inspired great loyalty among the conquered people, making Temüjin stronger with each victory.
