Background
In 1592 (the 25th year of King Seonjo's reign), when a Japanese army of about 200,000 invaded Joseon, the central military system ranked fifth in the early Joseon period and the regional defense system of jingwan (鎭管) and jeseungbangnyak (制勝方略) failed to fulfill their roles. Therefore, the royal court raised the need for a new military organization and expedited the reorganization of the military system to overcome the war. The organization of the new military institution played a significant role in the Ming Dynasty's military tactics. During the Imjin War, when 40,000 Ming soldiers came to assist Joseon, General Nak Sang-ji (駱尙志) of the Ming Dynasty mentioned the importance of military training to Ryu Seong-ryong (柳成龍). Upon receiving the permission of King Seonjo, Liu Sung-ryong trained Nak Sang-ji in military tactics, including the use of weapons such as gongbang (棍棒), deungpae (籐牌), nangseon (狼筅), jangchang (長鎗), dangpa (鐺鈀), and ssangsudo (雙手刀).Establishment
The Royal Guard Command was established In response to the turbulent domestic situation caused by the Injo Coup of 1623 and increasing pressure from the Later Jin Dynasty. King Injo took a hard line against the later kings. Particularly, the Seoin faction of the Injo administration, unlike during the reign of KingOrganization
During the reign of King Injo, the Royal Guard Command (Eoyeongcheong, 어영청) was established. Injo, who ascended to the throne in 1623 through the Injo Coup, had to devise measures against the pressure from the Later Jin Dynasty (Houjin, 후금). Therefore, in 1624 (the 2nd year of Injo's reign), Yi Gwi (이귀) was appointed as the Royal Guard Commander (Eoyeongsa, 어영사) to protect the king, marking the beginning of the Royal Guard Army (Eoyeonggun, 어영군). To strengthen the king's protection there, seven skilled soldiers were selected from nearby mountainous regions for large towns, four for medium-sized towns, and two for small towns. AfterStructure
The basic military command structure, included two Langdang officials in charge of military affairs, in addition to the fundamental military command system. There were also 12 Kyo-nyeom officials responsible for military training, such as the Kyo-nyeom officials and 10 Flag officers, as well as 15 headquarters officers, 11 officers from the Chulsin, 52 officers from the Gwajeonbyeong, 30 separate warriors, 1 horse doctor, and 300 Jae-gyeong officers. Among them, some were established as needed, but like the training headquarters, there were also concerns about the excessive promotion of non-military officials, which can be seen as a concern of the Joseon Dynasty. The main camp of Eo-yeongcheong was located east of Namseo Myeongjeokbong's Nammun Gate, and as its scale expanded, Shinwon was established in Iryeon, Dongwon was installed outside Seoninmun Gate, but when the king was in Gyeonghuigung Palace, it was stationed outside Kaiyangmun Gate. In addition, North Second Camp was located in Saejik-dong, but when the king was in Gyeonghuigung Palace, it was stationed outside Mudeomun Gate. In addition, Jipchun Camp was located outside Jipchunmun Gate, and the South Granary, which stored provisions, was located in Namsodong.Division
Immediately after its establishment, the Royal Guard Command pledged allegiance to Princess Bacheonju duringHyojong
Subsequently, during the reign of King Hyojong, as part of the Northern Expedition plan, the U'yeong Corps was significantly expanded. In 1652 (King Hyojong's 3rd year), Hyojong appointed military specialist Yi Hwan as the U'yeongdaejang and sought to enhance the strength of the U'yeong Corps as one of the primary projects for military expansion into a year-round military camp. As a result, the number was increased to 21,000, more than triple the previous size. Instead, 21 groups of 1,000 troops were stationed at the military headquarters. However, after King Hyojong's reign, it became difficult to maintain the operational system due to financial constraints. The recruitment-based system was changed to a compulsory system where the Hyanggun (local defense forces) from the six provinces, excluding Pyeongan and Hamgyeong, were obliged to carry out rotations. This change led to a significant increase in the number of Boins supporting the U'yeong Corps. However, after King Hyojong, the enthusiasm for northern expeditions waned, and the power struggle between factions intensified, complicating the change of government. This increased the burden of maintaining Eoyeongcheong, ultimately leading to a change in the guard system to the rotational system of the local militias (Xiangjun) in the six provinces, excluding Pyeongan and Hamgyeong. During King Hyojong's reign, Eoyeongcheong was organized with five departments, three separate offices, and one separate central outpost. Additionally, separate cavalry units called Bomyeongdwi and artillery units called Beopajeon were established within Eoyeongcheong.Sukjong
The Royal Guard Command was initially organized into 5 Bu (部, divisions), Byul Samsa (別三司, separate three offices), and Byul Jungcho (別中哨, separate central posts) according to the Sok'o Law (束伍法). Then, in December 1704 (King Sukjong's 30th year), it was reorganized into 1 Yeong (營, battalion) consisting of 5 Bu, 1 Bu consisting of 5 Sa (司, offices), and 1 Sa consisting of 5 Cho (哨, posts), totaling 125 Cho with a total strength of 16,300 personnel. Furthermore, the basic unit of the Sok'o Law, which is the Cho's military organization (軍摠), was composed of 127 personnel (1 Cho = 3 Gi, 1 Gi = 3 Dae, 1 Dae = 10 Jeonggun, 1 Hwabyeong, and 1 Bokmagun). These Hyanggun (향군) soldiers were divided into 25 rotations, with 5 Cho serving in rotation for two months, resulting in approximately 700 soldiers stationed in Seoul. In addition to the basic troops, which were the Hyanggun, there were 150 Knights (기사), 160 Byulpajin (別破陣, special assault troops), various Kyungpyoha-gun (경표하군, soldiers responsible for guarding the capital) numbering 781, 40 Sumungun (守門軍, gatekeepers), 16 Gunposujik (軍鋪守直, military storekeepers), 301 Bonabyeong (本牙兵, palace guards), 87 Hyeonrokabyeong (懸錄牙兵, elite guards), 50 Chijungbokmagun (輜重卜馬軍, logistics and transport troops), 100 Yanghwajinabyeong (楊花津牙兵, special task force), 9 Kyosa (敎師, instructors), 40 Gyeombulpajin (兼別破陣, dual-purpose assault troops), 700 Hyangkisa (鄕騎士, local knights), and 56 Pyohagun (標下軍, troops responsible for flags). There were various types of miscellaneous troops in addition to the Hyanggun, some of which were deployed for special occasions such as Pyohagun or Sumungun, while others, such as Chijungbokmagun, only served when necessary, and Hyangkisa, which had the name but were actually Sumugun. To maintain the U'yeong Army, the Bop (保) was established, consisting of 17,475 Jabo (資保, reserve) personnel, 51,750 Gwanbo (官保, officials), 980 Byulpajinbo (special assault troops reserve), and 3,729 Kisabo (기사보, knights reserve), totaling 72,359 personnel, which was nearly four times the size of the Hyanggun. Military personnel in the U'yeong Army were appointed as Suryeong (수령, military leaders) capable of martial arts training in each region, serving as Gyeompachong (兼把摠, dual-commanders) in charge of their training. However, when the Geumwiyeong was established during King Sukjong's reign, in December of the 30th year (1704), Eoyeongcheong was reorganized along with Geumwiyeong, resulting in a total of five departments, 25 companies, 125 units, and 16,300 soldiers. Each unit consisted of 127 soldiers (1 unit = 3 flags, 1 flag = 3 companies, 1 company = 12 soldiers, including 10 regular soldiers, 1 artillery soldier, and 1 Boeundae soldier). With this reorganization, Eoyeongcheong divided the 125 units into 25 groups, with each group consisting of five units. They rotated every two months, ensuring that approximately 700 soldiers were stationed in the capital at all times. The restructuring of Eoyeongcheong aimed not only to establish uniformity with the Geumwiyeong, which was organized as a unified Xiangjun, but also to strengthen the defense of the capital by maintaining a standing reserve force of around 700 soldiers in Seoul.Duties
Funding
The financial foundation of Eoyeongcheong relied on the Boeun system. Expanding and strengthening this central military force posed a significant financial burden. To address this, the government established "Boman" for them. If they were of good character, they were assigned one "Boman," and if they were of lower status, they were granted the benefit of exemption from corvée labor. The soldiers serving in the rotating guard duty of Eoyeongcheong were given three Boeun each. One Boeun was solely allocated for the expenses incurred during guard duty (資保), while the other two Boeun were used to cover the expenses during their stay in Seoul, resulting in a total of 80,000 Boeun for the soldiers at that time. Furthermore, the Xiangjun themselves, which constituted the mainstream of Geumwiyeong, were maintained by the local militias in the six provinces and brought benefits to the national finances. Looking at the number of Boeun assigned to the Geumwiyeong soldiers at that time, 17,475 were allocated to civilian officials (資保), 50,175 to government officials (官保), 780 to Beopajeon soldiers (別破陣保), and 3,729 to cavalry soldiers (騎士保), totaling 67,650. This means that the number of Boeun allocated to the Xiangjun soldiers was about four times that of the Geumbok soldiers. As a result, each infantry soldier received one Boeun, and each Boeundae soldier received two Boeun to cover their equipment needs. The government allocated a significantly higher number of Boeun to government officials, providing 1 liang of travel funds (旅需錢) and 9 du of monthly provisions for each soldier (increased to 3 du for those serving as auxiliary servants). While this large number of Boeun didn't impose a significant burden on the national finances, it relatively increased the burden of corvée labor. This led to continuous issues regarding the conscription system. U'yeongcheong operated under a system called "Bangsang gyulryeojae" (번상급료제), which provided soldiers with compensation in the form of 9 dou (斗) of rice per month in exchange for one rotation of duty. For each regular soldier (Jeonggun, 정군), one person was assigned as a "Jabo" (자보) who was responsible for supplying cloth. The Jabo, similar to the conscription system in early Joseon, provided military uniforms and covered the expenses of soldiers' rotation duty, while the regular soldiers were assigned to agricultural work during their rotation period. Additionally, for each regular soldier, two "Gwanbo" (관보) were assigned, and they paid military service taxes to U'yeongcheong, which constituted a source of revenue for compensation. The Gwanbo system was designed to address the issue of regular soldiers being unable to fulfill their military duty due to the escape of their assigned Bo-in (보인, person responsible for supplying cloth). With this system, U'yeong soldiers received compensation from the military camp while being able to serve their rotation duties at U'yeongcheong.Dissolution
While operating U'yeongcheong, a problem arose with the overall increase in the burden of military service (Yeokchong, 역총). As U'yeongcheong soldiers performed their rotation duty, King Sukjong (reigned 1674-1720) reduced the size of the regular army to less than 16,000 soldiers and also decreased the number of Bo-in and other military personnel. However, due to difficulties in the national finances, discussions of its abolition emerged. Moreover, concerns arose that the short-term rotation of soldiers might lead to insufficient compensation, resulting in an increase in crimes within the capital. The issue of how U'yeongcheong soldiers were treated was also connected to the problem of military weakening. It merged with the Chongyungcheong (총융청) and Geumwiyeong (금위영) in 1881 (King Gojong's 18th year) to become the Jangeoyeong (장어영), and then changed to Chong'oyeong (총어영) in 1884, before being abolished in 1894.See also
