보령 지역의 고대 사회와 백제

Abstract

Based on the literature and the latest archaeological data, this study examined the ancient society of the Boryeong region through local forces in the ancient Boryeong region and their changes. After reviewing the major ancient remains in the Boryeong region, it was found that remains from the Ungjin and Sabi periods dominate the Boryeong region rather than those from the Hanseong period of Baekje. In addition, the Boryeong region is bordered by Daecheoncheon Stream, with remains concentrated in the northern part of the region, mainly in Jupo-myeon and Cheongna-myeon, and in the southern part of the region, along the Ungcheoncheon Stream, there are many remains where Baekje’s prestige items were excavated. This suggests that after Baekje’s transfer of the capital to south, the Boryeong region gained prominence as it became closer to Baekje's capital. Chapter 3 examined the changes in the major local forces in the Boryeong region and Baekje’s entry into the Boryeong region. Local forces in the Boryeong region were located in places that were easily defended by natural geography based on plains formed along water systems such as Bongdangcheon, Daecheoncheon, and Ungcheoncheon Streams. The Changam-ri Togwangmyo force was the first to rise to prominence in the Boryeong region, but it has only been identified as a local force. Unlike Baekje’s regional expansion in the 3rd and 4th centuries through literature and archaeological data, in Boryeong, the tomb of the central Baekje is not identified until the 5th century at Baekje Tombs in Myeongcheon-dong. This is because Baekje’s entry was based on the surrounding regions such as Seosan and Hongseong. After Baekje’s entry, the Boryeong region became closer to the capital of Baekje, and in the relationship with the center of Baekje, forces around the Boryeong-ri tombs and Yeonji-ri remains and the Guryong-ri ruins in Ungcheon emerged as the main forces in the Boryeong region. Chapter 4 examined the nature of the counties organized in the Boryeong region during the Sabi period. Baekje seems to have organized each county in the Boryeong region, which was attached to Geolgi-gun and Seollim-gun, in consideration of the natural geographical environment of the Boryeong region. In the north, Sinchon-hyeon was established to defend the Cheonsuman area, and in the south, Sapo-hyeon was established to defend the Geumgang Estuary and Ungcheoncheon Estuary, which connected to Baekje’s capital. Meanwhile, Sapo-hyeon was a key point on the transportation route that connected to the Baekje’s capital, Sabi through Ungcheoncheon Stream. In particular, it is believed that Sapo-hyeon also served as a guardian of Ohapsa Temple, which was likely a temple within the region of Sabi Castle Town.
