Exploring the location of the city hall in Jangsan-gun and the transition of Gun-hye on during the Goryeo Dynasty

Abstract

The name of the town, Jangsan-gun (Gyeongsan-si), was officially given in 757. In 927, at the Battle of Gongsan Dongsu, Wang Geon was defeated by Gyeon Hwon of the Later Baekje. However, the residents of Gyeongsan cooperated with Goryeo. As a reward, Wang Geon changed the name of Jangsan-gun to a better meaning. Jangsan-gun (Jangsanseong) does not know its exact location. However, it was revealed that the site of Gyeongsan City Hall during the Joseon Dynasty was the seat of the Goryeo Dynasty. It was also analyzed that this place would be the site of Jangsan Fortress. The transition of Gun-hyeon of Jangsan-gun of Goryeo began with the Taejo period. Jangsan-gun was transferred to Donggyeong Yusugwan Gyeongju in February 1018 (9th year of King Hyeonjong). In 1172 (the 2nd year of King Myeongjong), Gammu was dispatched. When King Chungseon took the throne, Jangsan-gun was changed to Gyeongsan-hyeon to avoid the king's name. This was December 1308. In 1317 (4th year of King Chungsuk), Gyeongsan-hyeon was said to be the hometown of Il-yeon and became Gyeongsanhyeonryeonggwan. In 1390 (2nd year of King Gongyang), it was elevated to Gyeong san-g un as it was said to be the hometown of King Gongyang's queen.
