This article reveals that the rebellion of Cho Wi-Chong(趙位寵, ?∼ 1176), which occurred in Seogyeong(西京) and Yanggye(兩界) was the counter-military coup in September 1174 through analyzing the cause and the process of it. The rebellion of Cho Wi-Chong was a political event with “eliminating Yi Ui-Bang(李義方, ?∼1174) and Chong Chung-Bu(鄭仲夫, 1106∼1179)” as the slogan, recognizing King Myeongjong(明宗. reign 1170∼1197) as a righteous king. Although Cho Wi-Chong had his own military foundation, the rebellion was the counter-military coup in the way that he insisted to eliminate the illegitimate military rulers and, at the same time, to hold a funeral of King Uijong(毅宗. reign 1146∼1170) who killed by them. In other words, the rebellion has a significant meaning that it was the biggest rebellion against the early Military Regime, respecting the existence of Goryeo king’s status.
