Dream of the Emperor is a South Korean television series that aired on KBS1 from September 8, 2012 to June 9, 2013 on Saturdays and Sundays at 21:40 for 70 episodes.

Kim Yu-sin was a 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.
