Yeum Moon
Kim Yushin (595 – 1 July 673) was a general in 7th-century Silla. He led the unification of the Korean peninsula by Silla under the reign of King Muyeol of Silla and King Munmu of Silla. He is said to have been the great-grandchild of King Guhae of Geumgwan Gaya, the last ruler of the Geumgwan Gaya state. This would have given him a very high position in the Silla bone rank system, which governed the political and military status that a person could attain.
Much of what we know about Kim's life comes from the detailed account in the Samguk Sagi, Yeoljeon 1-3, and the much briefer record in the Samguk Yusa, vol. 1.
Kim Yushin was the son of General Kim Seohyeon and Lady Manmyeong, who was a daughter of King Jinheung of Silla. He was born in Gyeyang, Jincheon County in 595, became a Hwarang warrior at just 15 and was an accomplished swordsman and a Gukseon (국선, 國仙; Hwarang leader) by the time he was 18 years old. By the age of 34 (in 629) he had been given total command of the Silla armed forces. Three years after Princess Deokman became Queen Seondeok of Silla, who kept Kim Yushin as commander in chief of the royality.
