신라 진지왕 폐위에 관한 재검토

Abstract

King Jinji is the only king dethroned in Shilla. SamgukSagi says that he died in the 4th year of his reign, while Samgukyusa says that he died after he was dethroned by nobles. Previous studies take his dethronement as true. This paper assumed based on SamgukSagi that he had not been dethroned, and tried examining the validity of that assumption through a principle of royal succession. According to the result of an analysis of the lineage of King Byolhyu where the royal succession was done in a similar fashion to the lineage of King Jinheung, the basic principle of royal succession was that it should be done according to father-to-son succession, and when the legitimate son was young or there was no legitimate son, the right of succession was given to the second son, a younger brother of the second son, or the son-in-law. In this case, the principle of inheritance within generation was partially applied, the principle based on special treatment for the elderly, as you can see in the origin of Isageum. If this applies to the lineage of King Jinheung, legitimate grandson Baekjeong (King Jinpyeong) was young after the death of crown prince Dongryun, and therefore the second son King Jinji came to throne. After the death of King Jinji, Baekjeong came to throne, as he reached the age at which he could come to throne. Meanwhile, after King Jinpyeong came to throne, he granted the title of Galmunwang, which would be granted to very high-ranking personages in early Silla, to his two younger brothers. By doing so, the royal succession was limited to the lineage of Dongryun. In addition, he excluded the lineage of King Jinji from royal succession by marrying his son Yongsu to his second daughter. But since not only King Jinpyeong but also his two younger brothers had no sons, he designated his first child Deokman as his successor according to father-to-son succession, and she became the first Queen of Silla. Jinjongseol (眞種說, meaning "the real tribe of Buddha") and Seong-gol (the saint class) were the sanctification of the lineage of Dongryun, and were the justification and consecration of Queen Seondeok. The mid-ancient period aimed for father-to-son succession. But inheritance within generation partially acted as well, and in that process the period ended up implementing intermarriage to strengthen father-to-son succession. And the period came to an end with the extinction of Seong-gol.
