The history of Korean martial arts is as old as the land itself and can be traced as far back as the prehistoric era, where primitive weapons made of wood and stone were used for hunting and fighting. As early as 2707 BC, the Korean warlord Chi-Woo, also known as Jaoji, reigned as the “god of war” in what is now Mainland China. Since then, the majority of Koreans migrated and settled in the region of the Korean Peninsula, where there have been more than a thousand recorded instances of foreign invasions. Consequently, the Korean people developed unique martial arts and military strategies in order to defend themselves and their territory. Most of these Korean martial arts fall into three main groups or branches, namely tribal, Buddhist, and royal court martial arts.
