Kim Mu-ryeok (518 – 16 October 579) was a Silla general under King Jinheung in the mid-6th century.
[1][2] He was the second son of King Guhae, the last ruler of Geumgwan Gaya, who had joined his family with the true-bone elites of Silla.
After his father's surrender in 532, Kim joined the Silla military at the high rank of gakgan.
After taking the area, Kim was made the military governor (군주; 軍主; gunju) of Sinju (신주; 新州).
[3] In 554, he met the Baekje armies at Gwansanseong Fortress (present-day Okcheon, South Korea), killing King Seong and four of his ministers, and taking some 29,000 prisoners.
