ABSTRACT

This paper examined the lineage of Isabu and the change of his political position during the reign of King Jinheung. Isabu was a grandchild of Paho Galmunwang who was the second son of the King Nulji. Isabu attacked and occupied the Kaya country early in the King Jijeung’s reign. From 505 to 512 as Siljig Gunju and Haseulla Gunju, Isabu conquered the Usanguk and led the Jeong corps that was stationed around the east sea area to prepare for the Goguryeo dynasty’s expansion toward the southern regions of the korean peninsula and the invasion of Whae. Leading 3,000 military, he attacked 4 Chon including the Geumgwan(Gimhae city) and took it in 529 during the King Beobheung’s era. After King Jinheung came to throne, Isabu led a political situation as Byeongburyeong and Sangdaedeung during the period under a regency by Jisotaehu and early reign period of King Jinheung. Since 551, King Jinheung began to control politics by changing the title of his royal year to Gaeguk and constructed his direct government system. At the same time Isabu supported the governance of King Jinheung behind the curtain as a representative of the Jingol nobility. After the bond between Silla and Goguryeo got weaker in 568, King Jinheung gave up further territorial expansion and chose to defend his new territory and resolve the anxious state of mind of people that was caused by a long-term war. In the 570s, Isabu may have been already dead. Then even though he was even alive, his influence must have been insignificant. From around 570s to King Jinji’s period, Geochilbu had the great influence on national administration on behalf of the Isabu.
