As shown in the table 1, the territory of Sakju that dominated 12 Gun´s and 26 Hyeon´s reached Hoengseong in the east, Gapyeong in Gyeonggi-do (province) in the west, Yeongju in Gyeongsangbuk-do in the south, and up to Deokwon in Hamgyeongnam-do for its administrative districts taking Chuncheon as a center nowadays. The territory of Myeongju that dominated 9 Gun´s and 25 Hyeon´s reached the Donghae ocean in the east, and Yeonghae, Yeongdeuk and Cheongsong in Gyeongsangbuk-do in the south, Pyeongchang and Jeongseon in the west, and Anbyeon in Hamgyeongnam-do in the north for its administrative districts taking Gangneung region as its center. In other words, the regions of Gangwon-do under the 9-state System included the Donghae ocean in the east, from Yeongdeuk in Gyeongsangbuk-do through the districts connecting Cheongsong, Yeongju and Punggi in the south, from Danyang and Jecheon in Chungcheongbuk-do to the district of Wonju through connecting Gapyeong, Cheorwon and Hoeyang in the west, and Deukwon and Anbyeon in Hamgyeongnam-do to the regions connecting Hoeyang in the north. It corresponds to the regions in Gangwon-do and some parts of Gyeongsangbuk-do, Chungcheongbuk-do and Hamgyeongnam-do as its controlling territories nowadays. The local administrative system of the Gangwon-do regions under the 9-state system at the time of the Silla Kingdom, which were divided into two (2) Ju´s, Sakju and Myeongju, and were subdivided into 21 annexed Gun´s and 56 annexed Hyeon´s. The system experienced many changes when entered into the Goryo (Korea) Kingdom. The Goryo Kingdom that unified the post-three Kingdoms in 939, were not in the capability to control each administrative district through dispatching its central officers from the central government, since King Taejo of Goryo was king in name only at the beginning stage of unification, and the sovereign power was extremely limited. Those districts were still under the control of independent district governors, and the central government could not rule each district through dispatching its central government governor to those districts directly.

The dispatch of its district governor became realized at the time of King Seongjong, when the sovereignty of king established. In other words, in the 2nd year of King Seongjong in 983, the central administrative system was first established, and therefore, the King organized the nation into 12 Mok´s (Mok for one of administrative unit), to which its district governors were finally dispatched and became to be in direct control over the regions. Before the 12 Mok´s were organized, the central government officers of Geumyu and Jojang, and Jeonunsa were dispatched to each region where the district governor was ruling. Geumyu and Jojang, as temporary central government dispatchers, acted as collecting taxes and materials in the corresponding regions, while Jeonunsa were responsible to transport the collected taxes and materials in the regions to Gaegyeong, its capital city of Goryo Kingdom. In other words, the taxes that the district governors collected, and Geumyu and Jojang gathered, while Jeonunsa transported the collected and gathered taxes and materials to the central government. The 12 Mok´s organized at the time were Gwangju, Yangju, Chungju, Cheongju, Gongju, Jinju, Sangju, Jeonju, Naju, Seungju, Hwangju and Haeju. The main purposes of its establishments were securing the core clans of the districts, while controlling those district family clans through dispatching the administrative officers from the central government to the regions, organizing the entire nation into 12 administrative districts. At the same time, Jujinsa´s were dispatched for military purposes in the national boundaries of the northern east and northern west districts, and thereby in the early times of Goryo Kingdom, its district administrations were finally established with its dual system, people and civilian-oriented administration of 12 Mok´s and military-oriented administration of Jejujinsa´s. Namely, the sovereign system of central government was formed in the system with civilian 12 Mok´s in the south provinces, and military system in the northern boundary regions of the northern east district and northern west district. Under the 12 Mok´s system, the comparison of the Gangwon-do with the 9 Ju´s 5 Sogyeong of the Silla Kingdom is reviewed in the following table 2.

As shown in the above table 2, the whole nation was organized into 12 Mok´s, and while the Kingdom either maintained the existing bases or established new Mok´s when the existing Mok´s became extinguished. In the south province regions, the Kingdom established new bases in the Hwanghae-do regions. Sakju, Myeongju and Bukwongyeong which existed in the northern west regions of Pyeongan-do and the northern east regions of Gangwon-do were extinguished, however, the clear records regarding the changes are not found, in the respect that the reorganization made in the 2nd year of King Seongjong in 983, when the nation were ruled under 12 Mok´s System, were made on the south province regions. And, therefore, the reorganization was not directly related with the northern west regions of Pyeongan-do, and the northern east regions of Gangwon-do. This was made in order to prepare against the attacks from the northern Georan tribes, and the Ahnbukdaedoho-busa (government officer) were dispatched to the west northern boundaries of Yeongju, while guardians were dispatched to Sunju, Euiju, Eunju, Sukju and Jaju. Myeongju in the northern east boundaries were reorganized to Haseo-bu. As explained, the dual district system, consisted of as the administrative system of the 12 Mok´s in the south provinces, and the military oriented system in the northern west boundaries, changed in the 14th year of King Seongjong in 995.

The reorganization was patterned after the Chinese Dynasty Dang´s system by adopting the Jeoldo-sa (sa for a government position) system and 10-Do´s (province) system as its local officers. As the administration-oriented 12-Mok System was reorganized into the Jeoldo-sa system, which was military oriented sovereign organization, the 12 Jeoldo-sa´s were newly established instead of the existing 12 Mok´s in the regions. In other district, total 80 local officers were dispatched including 5 Dohobu-sa´s in 2 Yusu´s, 7 Danryeon-sa´s in the 7 Do´s, 15 Jasa´s, 21 Bangoesa´s, and 7 Jin-jang´s.

Also, total 7 local officers were dispatched in the Gangwon-do region, consisted of as 5 Danryeon-sa´s in Gyoju, Chunju, Dongju, Myeongju and Cheokju as well as 2 Bangoe-sa´s in Goju (Goseong) and Yeonju (Sakju). Along with this, the nationwide administrative districts were reorganized into 10 provinces, which were Gwannae-do, Jungwon-do, Hanam-do, Gangnam-do, Haeyang-do, Yeongnam-do, Yeongnam-do, Sannam-do, Sakbang-do and Paeseo-do, where 7 Jin´s, breaking down into 449 Hyeon´s, into128 Ju´s were belonged. Sakbang-do, where 7 Ju´s 62 Hyeon´s were ruled, falls approximately on the areas of the today´s Gangwon-do. Despite the above system under 10-Do´s, the central point of the district administration was still by the local officers belonged to the district governor. Though the intention of dividing the nation into 10-Do´s dependent upon the geographic topographies could be understood as the central government´s objective to make the local districts placed under its definite control and sovereignty, in the viewpoint that only Jeonun-sa´s were dispatched from the beginning of the Kingdom as a temporary or preliminary system. The central points after establishment of 10-Do´s system were still the local officers along with the 12 Jeoldo-sa´s. The 10-Do´s, intended for the upper administrative organizations, which ruled over the local governors, were still not completely functioning at the time.

Therefore, the 10-Do´s were not the administrative districts that placed between the central government and the local governors, but only took the responsibilities as Jobujeonwun and districts that required the watchful inspections. In other words, the 10-Do System was transitional from the Ju-oriented system toward the wide-area local system that included the Ju´s, as its part of strengthening the sovereign system, but was not completely settled as a district administrative system. The Jeoldo-sa system as its local officers organized in the 14th year of King Seongjong in 995 became gradually shifting to the people-oriented system, as the Jeoldosa System of the Gwanchal-sa, Dodanryeon-sa and Danryeon-sa were abolished, leaving only Bangoejin-sa, Hyeonryeong, and Jinjang in the northern east boundaries. In addition, when at the time of King Hyeonjong in 1012, the Jeoldo-sa´s of 12-Ju´s were completely abolished as Donggyeongryu-su was abolished while Gyeongju Bangoe-sa was instead installed, and there were 5 Dohobu-sa´s and 75 Doanmu-sa´s. At the 9th year of King Hyeonjong in 1018, it was reorganized into 4 Doho-bu´s, 8 Mok´s, 56 Jijugun-sa´s, 28 Jinjang´s and 20 Hyeonryeong´s while abolishing Anmu-sa. Accordingly, the military Jeoldosa System was transformed to the people-oriented Mok-Jijubugunsa -Hyeonryeong System in the south provinces, while, Bangoesa-Jinjang were only installed in the boundary areas. As a result of all the administrative system reorganization, the number of local officers increased from 80 under the King Seongjong (14th year of Seongjong) to 116 under the King Hyeonjong rule in the entire country, thereby the central sovereign system was strengthened, and with this, the local district system of Goryo Kingdom became established.

Afterwards, the local administrative system under Goryo rule, King Hyeonjong divided the nation into 5 Doyang-gye (gye for boundary), and 4 Gyeong´s and 4 Dohobu´s and 8 Mok´s were installed. Under the system, the large-scale local administrative system was reorganized while installing 15 Bu´s, 335 Hyeon´s and 29 Jin´s. The 5 Do´s at that time were Yanggwang-do, Gyeongsang-do, Jeolla-do, Gyoju-do and Seohae-do under the people-oriented system, and the two Gye´s were Donggye and Bukgye under the military-oriented system. As for the Gangwon-do, most of the Yeongdong regions, the east areas of the Taebaek Mountains and the lower regions of Jeongpyeong in Hamgyeongnam-do were largely included in the Donggye, while most of Yeongseo regions with exception of part of Yeongseo southern part which were included at the time in the Yanggwang-do, were included in the Gyoju-do.

The administrative organization of the Donggye and Gyoju-do, where most of Gangwon-do were included, was consisted as 1 Doho-bu, 9 Gun´s, 8 Hyeon´s, 10 Jin´s and 17 annexed Hyeon´s, and the Gyoju-do was consisted as 3 Gun´s of main Hyeon´s and 25 annexed Hyeon´s, which were main Hyeon´s of 1 Doho-bu, 8 Hyeon´s and 10 Jin´s, along with 39 annexed Hyeon´s. The 5 Do´s and Yanggye System as a dual administrative system with the people-oriented 5 Do´s and military-oriented Yanggye (two boundary areas), kept maintained until the end of Goryo Kingdom without major changes through ruling with Gun-Hyeon under its jurisdiction by dispatching the Anchalsa, its local governors to the 5 Do´s and Byeongmasa to the Yang-gye.
