Choi Hong Hi
Won Kuk Lee, a Korean student of Funakoshi, founded the first martial arts school after the Japanese occupation of Korea ended in 1945, called the Chung Do Kwan. Having studied under Gichin Funakoshi at Chuo University, Lee had incorporated taekkyon, kung fu, and karate in the martial art that he taught which he called "Tang Soo Do", the Korean transliteration of the Chinese characters for "Way of Chinese Hand" (唐手道). In the mid-1950s, the martial arts schools were unified under President Rhee Syngman's order, and became taekwondo under the leadership of Choi Hong Hi and a committee of Korean masters. Choi, a significant figure in taekwondo history, had also studied karate under Funakoshi. Karate also provided an important comparative model for the early founders of taekwondo in the formalization of their art including hyung and the belt ranking system. The original taekwondo "hyung" were identical to karate "kata". Eventually, original Korean forms were developed by individual schools and associations. Although the World Taekwondo Federation and International Taekwon-Do Federation are the most prominent among Korean martial arts organizations, "tang soo do" schools that teach Japanese karate still exist as they were originally conveyed to Won Kuk Lee and his contemporaries from Funakoshi.
