Warfare and foreign relations

Although Kublai restricted the functions of the kheshig, he created a new imperial bodyguard, at first entirely ethnic Han in composition but later strengthened with Kipchak, Alan (Asud), and Russian units. Once his own kheshig was organized in 1263, Kublai put three of the original kheshigs under the charge of the descendants of Genghis Khan's assistants, Borokhula, Boorchu, and Muqali. Kublai began the practice of having the four great aristocrats in his kheshig sign jarligs (decrees), a practice that spread to all other Mongol khanates. Mongol and Han units were organized using the same decimal organization that Genghis Khan used. The Mongols eagerly adopted new artillery and technologies. Kublai and his generals adopted an elaborate, moderate style of military campaigns in southern China. Effective assimilation of the naval techniques of the Han people allowed the Yuan army to quickly conquer the Song.
