Kim Yu-shin, general of Silla (b. 595)
Kim Yu-sin (sometimes romanized Kim Yu-shin, Gim Yu-sin, or Gim Yu-shin) (595 – 18 August 673) was Korean military general and politician in 7th-century Silla. He led the unification of the Korean Peninsula by Silla under the reign of King Muyeol and King Munmu. 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 is known 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.
