Ssangseong Prefecture (;) was an administrative division of the Yuan dynasty established in 1258 in modern-day Kumya County, South Hamgyong Province, North Korea. It was founded as a base for conquest and domination of northern Goryeo territory together with the Dongnyeong Prefectures, which had jurisdiction over southern Jabi pass. In 1356, Gongmin of Goryeo got out under the influence of Yuan dynasty, attacked Yuan dynasty together with Dongnyeong Prefectures and restored the land.
In 1258, Yuan dynasty general San Gil and Bo Ji invaded northeastern Goryeo along with the eastern Jurchen. Tongbungmyŏn military commissioner Sin Chipp'yŏng forcibly removed civilians who took refugee on Jeodo island to Jukdo island in Tŏkwon. However, Cho Hwi and T'ak Ch'ŏng killed Pak Ingi, governor of Deungju, and Kim Sŏnbo, governor of Hwaju, and then Sin Chip-p'yŏng. They then surrendered the land north of Cheollyeong Pass to Yuan dynasty. The Yuan then established the Ssangseong prefecture to govern the northeast. At that time, Cho Hwi was nominated as the General Superintendent and Tak Cheong was nominated as a chiliarch.[1] [2] Afterwards, the position of General Superintendent was inherited by Cho family. After Jo Hwi, the position was inherited by Cho Yanggi who was the son of Cho Hwi, Cho Rim, grandchild of Cho Hwi and Cho Sosaeng who was a great-grandchild of Cho Hwi. The position of chiliarch was also inherited by T'ak family.
On the other hand, Ch'oe Tan who made a rebellion in 1269, devoted 54 castles including Seogyeong and 6 castles including Seohae province to Yuan dynasty. Yuan dynasty renamed Seogyeong as Dongnyeong Prefecture and incorporated to their own territory. This decision has made regardless of Yuan dynasty's invasion.
After that, Goryeo came to fall to the position of receiving the original interference.
Ssangseong prefecture fell to Goryeo in 1356. Yu Inu who was a vice-minister of councilors became an officer for northeast troop and was commanded to seize control of Ssangseong prefecture by King Gongmin of Goryeo. He was sent to the front together with general of battalion Kong Pubo, Kim Wonbŏng and Yi Inim . Cho Ton, the uncle of General Superintendent Cho Sosaeng, and Yi Chach'un, the myriach of Hamju, sided with Goryeo and helped Goryeo take control of Ssangseong. General Superintendent Cho Sosaeng fled northwards and took shelter amongst the Jurchen.[3]
