In 1952, South Korean president Syngman Rhee witnessed a martial arts demonstration by South Korean Army officers Choi Hong-hi and Nam Tae-hi from the 29th Infantry Division. He misrecognized the technique on display as taekkyon,[1][2][3] and urged martial arts to be introduced to the army under a single system. Beginning in 1955 the leaders of the kwans began discussing in earnest the possibility of creating a unified Korean martial art. Until then, "Tang Soo Do" was the term used for Korean karate, using the Korean hanja pronunciation of the Japanese kanji 唐手道. The name "Tae Soo Do" (跆手道) was also used to describe a unified style Korean martial arts. This name consists of the hanja tae "to stomp, trample", su "hand" and do "way, discipline".[citation needed]
