新羅 聖德王代 毛伐郡城 築造의 背景과 目的

Abstract

Mobeolgun Castle is a great castle built in the border area with Ulsan city in the southeastern part of Gyeongju, North Gyeongsangbukdo. According to the literature record, Mobeolgun Castle was constructed in October 21st year of King Seongdeok, and was built to block the invasion route of Japan. In addition, although Mobeolgun Castle was recognized as a gate, it seems that the place name was attached because 臨關郡 was a place where facing the gate, which was the place where the castle was built. The size of Mobeolgun Castle was 12 kilometers, 39,262 people were mobilized for the castle, and the person who owned the highest post of Silla directed the construction project. In the related article, the purpose of the construction that Mobeolgun Castle was built to block the invasion road of Japan is transmitted, but when we consider the situation in Japan at that time, the movement that tried to invade Silla at that time was seen at all. In other words, at that time Japan was not in a situation to invade Silla in the first place. Therefore, it seems that the aim of building the Mobeolgun Castle found in the related article was only for promoting the construction business. It is true that Mobeolgun Castle had the function to prevent Japan's invasion route. However, the timing and location of the castle was the result of reflecting the subjective intention of Shilla's campaign power of the King Seong-deok’s Era. At the time of construction of the Mobeolgun Castle, despite the fact that Silla was not exposed to the military threat from Japan, despite the fact that the enforcement forces blocked the invasion route of Japan when laying the Mobeolgun Castle The reason was that Silla recognized Japan as hostile and invasion of Silla as a heterogeneous existence. The enforcement forces of the Seong-deok’s Era Silla need to evoke the perception of the Silla people to Japan on the grounds of an unusual response to the Japanese Silla Amnesty in 721, and furthermore they emphasized that they need to build Mobeolgun Castle and to stop the invasion route of Japan. Mobeolgun Castle is a Great Wall that visibly distinguishes specific areas and also functions as a gate from the institutional aspect. Construction of Mobeolgun Castle had a primary purpose in strengthening the kingship by visibly emphasizing the capital which is the direct jurisdiction of the king. The reason why Shilla 's regime forces of the Seong-deok’s Era built refilling county castles as part of measures to strengthen the kingdom and made reforms to the capital was because after the fall of Dalgubeol transition city plan led by King Sinmun, the existing capital city It was because he was devoting his efforts to develop into the capital as a unified kingdom and to build a dominance system based on the king. Since this was a policy to strengthen the kingdom at the same time, the regime power of Silla of the Seong-deok’s Era raised the problem which required national correspondence to prevent the invasion route of Japan as the name of the castle. Therefore, it is judged that the creation of the Mobeolgun Castle was a measure to strengthen the kingdom promoted by the unrest in Japan.
