Tang Soo Do

Tang Soo Do is a Korean martial art promoted by Hwang Kee that has roots in various martial arts including Shotokan karate, taekkyeon, Subak, and kung fu.The origin of Tang Soo Do can not be definitively traced to any single person. Lee Won Kuk is credited as being one of the first instructors of Tang Soo Do in Korea. Lee Won Kuk had an established dojang in Korea during the Japanese occupation of Korea. This school was called the Chung Do Kwan, or "Blue Wave School". According to Lee Won Kuk, this name was chosen to reflect it's connection to the Shotokan, or "Pine Wave School." Lee Won Kuk received Dan ranking from Funakoshi Gichin in Japan and he purportedly studied taekkyeon in An Gup Dong, Seoul, Korea and Kung Fu in Henan and Shanghai, China. Lee Won Kuk later was instrumental in developing the Korean martial art of Taekwondo.

The history of the Moo Duk Kwan (from which the majority of all modern Tang Soo Do stylists trace their lineage) can be traced to a single founder: Hwang Kee. Hwang Kee learned Chinese martial arts while in Manchuria. He also was influenced by the indigenous Korean arts of taekkyeon and subak. Hwang Kee learned much of the Moo Duk Kwan curriculum from a text on Okinawan Karate, presumably written by Gichin Funakoshi. In 1957, Kee made a discovery of Korean martial techniques in a text entitled the, "Muye Dobo Tongji."
