course, was not able to fight the young champion and fell down to the ground. Then, a young civilian official named Han Roe, insulted the general and even slapped him across his face in front of the king and many fellow soldiers. General Jeong, who could not stand the advisers' attitude anymore, knocked Han out and insulted him. The incident caused the long grievances of military to explode; young soldiers, notably Colonels Yi Ui-bang, Yi Go and Chae Won, urged Jeong to launch a coup d'état against the entire government and the king, who favored civilian officials over army. Jeong first ignored their opinion but later agreed to revolt against the government. With his order, in the name of commander-in-chief, the whole army rebelled against the king and his advisers. Almost all of advisers, including Kim Don-jung and Han Roe, were killed and King Uijong was overthrown. Jeong then set up a puppet king, King Myeongjong, beginning the 100-year military rule of Korea.

Then Yi visited Jeong, who adopted him as a son, only for a while. In 1173, a surviving civilian official Kim Bodang rebelled in northeastern border, trying to restore the civilian order under deposed King Uijong. Yi Ui-bang decided to assassinate Uijong; and after he killed the ex-king, Yi put down the rebellion, which put Yi on the peak of the power.

His despotic reign caused the grief of many people, and finally in 1174, a chain of rebellion that lasted for 50 years began in Pyongyang by Jo Wi-chong. Yi Ui-bang sent massive troops to put down the rebellion. General Jeong, who promoted himself as Prime Minister, decided to put an end to Yi's reign of terror. He ordered his son, Jeong Gyun, and his son-in-law, General Song Yuin, to kill Yi Ui-bang. Yi was finally murdered by Jeong Gyun, and the power passed to Jeong Jung-bu. Jeong continued to fight against rebels in Pyongyang; however, slaves and people of lowest class of present-day Gongju rebelled against the government. Jeong managed to crush the uprising
