古代 淸州地域의 歷史的 動向

A Historic tendency of ancient Cheongju(淸州) area

This essay is about the process of Baekje, Goguryo, and Silla having advanced to Cheongju area. Baekje first occupied Cheongju area among the Three Kingdoms. As the forming period of Baekje historical remains, the ancient tombs in Sinbongdong etc., has the lowest limit in the middle of sixth century, Cheongju was Baekje’s territory in the beginning of the period of Sabi(泗). The place name of Cheongju area in the period of Baekje was Nangbiseong. At the end of fifth century, Goguryo advanced to the northern and the eastern parts of Cheongju. Though Goguryo armies advanced to the southern part of Cheongju around A.D 529, they were not able to occupy it because of Miho river(美湖川) and around its defensive castles. In the end of fifth century, Silla also advanced to the southern and the eastern parts of Cheongju and encountered Goguryo, but Silla didn’t occupy it, either. After the end of fifth century, although Cheongju was still a territory of Baekje, it was a triangled area that Goguryo, Baekje, and Silla confronted one another in. After Silla won the victory at the battle of Dosal castle(道薩城) in 649, it occupied Cheongju. Silla that had destroyed Goguryo and Baekje established new systems of regional administration efficiently to rule the enlarged territory, and Minor Capital was established in Cheongju area. The place where Minor Capital was established is now the eastern and the western parts of Musim river(無心川), the back area of Uam mountain castle(牛岩山城) in the east and Bumo mountain castle(父母山城) in the west. 4 years after Seowon Minor Capital was establish, Seowon Minor Capital castle was constructed in 689. This means that the stronghold castle of Cheongju was moved from Bumo mountain castle to newly constructed Seowon Minor Capital castle. The place of newly constructed Seowon Minor Capital castle is convinced of Sandang mountain castle(上黨山城) that was constructed in the east of Cheongju.
