Many of us are familiar with the Hwarang of Silla, if only by the martial art of the same name. However, I have been reading through some Korean history books and I came across some information about a group that were very similar in functionality as the Hwarang, but were located in the Koguryeo kingdom (37bc - 668ad). These group also functioned as youth group that were trained in science, arts, and military arts. I have not done any deep research as of yet, but they could actually pre-date the Hwarang. As I get more information I will try to add to this thread. Just wanted to drop some food for thought.
