King Chungseon-wang, when he first ascended to the throne in 1298, tried to renovate the Goryeo institution of military mobilization, by securing more land units and distributing them all to households assigned for military duties. Then in 1308, when he returned to the throne after a 10-year stay upon Yuan, he chose a different tactic, and concentrated his efforts upon ensuring that the military households stay in good shape and in healthy condition which would enable them to respond to the government"s call more swiftly and willingly. In order to do that, he first gathered a large group of lowly servants from both the public and private sectors, and then intended to channel their labor force into individual households which could later serve as potential military units.
Chungseon-wang"s such efforts was a natural evolution from the previous institutions of former Goryeo kings, but it also surprisingly resembled the ongoing efforts conducted by the Yuan imperial government which was determined at the time to secure an adequate number of military servants and tie them into households that were slated for military deployments. King Chungseon-wang grew up in Yuan, studied the Yuan government"s policies since his youth, and was able to maintain a close relationship with Yuan emperor Wutsung. So he was well aware of certain problems inside Yuan that were destabilizing the Yuan government"s military administartion, and he was facing similar problems of his own in Goryeo as well. So, in an effort to graft certain policies upon some Goryeo-specific problems, and adapt certain methods to the Goryeo environment, he declared in 1307 that he would "newly define parameters concerning the relationship between individuals scheduled for military services and people who were not, using Yuan -generated policies and institution." This attempt was met with severe resistance from the Goryeo officials including Choi Yu-eom, and there were many other potential problems that had to be ironed out first. Chungseon-wang was forced to refrain from making any more attempts, and was left with no other chose but to pursue a policy that would be less provocative in the eyes of the Goryeo people. So he decided to impliment the above-mentioned policy of securing lowly servants and integrating them into military households. Although such actions taken by Chungseon-wang after 1308 must have been certainly "toned down" compared to his initial approach, they still were seemingly inspired by Yuan"s customary approaches to the said problem.
Chungseon-wang"s overall efforts to resuscitate the dying military institutions of Goryeo was quite thorough and imaginative. He utilized the existing conventions of Goryeo, while also putting all the foreign knowledge he accumulated in Yuan to a good use. As a result, he was able to delay the total collapse of the Goryeo military mobilization system.
