And there don't put some changes in culture.The Mongols were barbarians since in their battalions if a group of 3 or more soldiers fled from battle they were executed. Furthermore, if 10 escaped, the rest of the battalion were executed. Furthermore, a technique that they had was to place their children and wives at their disposal so that the enemy would think that there were many people.
