The purpose of this paper is to find out the current status and tasks of sword martial arts. So it reviews the policy tasks of sword martial arts focusing on the promotion policy of sword martial arts at King Jeongjo's. A comprehensive summary of this is as follows. First, King Jeongjo's policy to promote sword martial arts was achieved through compiling Muyedobotongji which is comprehensive sword martial book of three countries (Korea,China and Japan) starting from the Imjin Waeran. In addition, this policy aimed at Jang Yong-young soldiers’ acquiring regular military training to become experts in martial arts. At the same time, they gained financial stability due to the rewards of military training. Through this, Jang Yong-yeong's soldiers were transformed royal bodyguards with majesty. King Jeongjo emphasized the idea of proficiency in both literary and martial arts and promoted martial arts training such as archery, sword martial arts, horseback martial arts, and bare-handed martial arts. In addition, as part of the project to express filial piety toward his father Crown Prince Sado, his father’s tomb was relocated to Hyeonryungwon. In an attempt to strengthen the royal authority and the wealthy, Hwaseong Fortress was constructed in Suwon and Jang Yong-yeong was launched. Muyedobotongji was also compiled as an effort of his accomplishment. King Jeongjo's military martial arts have been inherited as traditional martial arts today and continue to this day. Second, the establishment of Jang Yong-young was part of the foundation for strengthening the royal authority by taking control of the military through military reform. Jang Yong-young's duties were palace guard, king bodyguard, royal trip escort. Jang Yong-young was divided into inner and outer camps, but the command system was unified, and various projects that inherited martial art were implemented with the expression of filial piety toward Prince Sado. In addition, the establishment of Jang Yong-young had two political purposes: preparing military power and expanding finances.Jang Yong-young's reality disappeared as a memory in history, but Jang Yong-young's literature, Jang Yong-yeong Daejeolmok , remains in the records, allowing specific facts to be grasped, and martial arts which were practiced in Jang Yong-yeong lead to an intangible heritage of traditional martial arts. Third, for the promotion of sword martial arts, five policy tasks can be suggested: ⓵ standardization of sword martial arts and techniques, ⓶ publishing a dictionary of sword martial arts, ⓷ providing visual and auditory material of sword martial arts ⓸ continuous planning of martial arts festivals, and ⓹ establishing a division of sword martial arts in the Ministry of Culture, Sports and Tourism. Based on these, sword martial arts will not stay in the past, but will be inherited and developed as an intangible asset for the future.
