The six years of this king’s reign were one long scene of turmoil and strife. In the first place the slaves revolted. They said “The high men are not made so by the decree of heaven. Great men are those who do well. Let us fight for our rights; Gen. Ch‘oe is from as low a grade as ourselves. Let us become high men too.” They rendezvoused at Heung-guk monastery and decided as a preliminary measure to demand from their masters the deeds of themselves (for slaves as well as houses were deeded property) and to burn them. They were betrayed to Gen. Ch‘oe who trapped a hundred of them, tied stones about their necks and drowned them in the river. The south was overrun by marauding parties whom the king bought off by gifts of food, clothes and land. In Chin-ju the governor’s servants locked him in his private dungeon, gathered a band of men and put to death all who would not join their standard. It is said that 6,400 men were killed because of refusal to join them. The same scenes were enacted in various places, notably in Quelpart and Kong-ju. In the midst of these scenes the king died and was succeeded in 1205 by his son Tok, posthumous title Heui-jong. We have now arrived at the threshold of events which were destined to make Asia one great battle-field and to cause the sovereigns of Europe to tremble on their thrones. The Mongols lived north of Yŭ-jin and were in a sense connected with them. Their first great chief was Ya-sok-hă (Yusuka) who first led the revolt which separated the Mongol power from the Yŭ-jin. He together with Keui-ak-on conquered forty of the northern tribes in quick succession and brought them all under his flag. His son’s name was Chŭl-mok-jin, the great Genghis Khan. It was now in the second year of Heui-jong, in 1206, that the great Genghis proclaimed himself emperor and named his empire Mong. Meanwhile Ch‘oe Chung-heun was not proof against the seductions of ambition and power, and we next find him seizing the people’s houses and building himself a magnificent residence adjoining the palace. People said of him that he buried a boy or a girl under each corner post. When the spring of 1212 opened, an envoy was sent to the Kin court but was intercepted by Mongol videttes who had by this time worked their way southward to a point that commanded the road between Koryŭ and Kin. The Kin people recovered the body and sent it back to Koryŭ.
