三国史記
The "Samguk Sagi", compiled by the general and official Gim Busik, emphasizes the military exploits of certain Hwarang, while the "Samgungnyusa" emphasizes the group's Buddhist activities. The biographies section of the "Samguk Sagi" describes young Hwarang who distinguished themselves in the struggles against the Gaya confederacy and later Baekje and Goguryeo. According to the "Hwarang Segi", as cited in the "Samguk Sagi" and "Haedong Goseungjeon", “...able ministers and loyal subjects are chosen from them, and good generals and brave soldiers are born therefrom.”
