Choi combined elements of Oh Do Kwan
Karate and Tang Soo Do to develop a style of the martial art known as "
Taekwondo"; his organization spelled it Taekwon-Do, (), which means "foot, fist, art" or "the way of hand and foot" and it was so named on 11 April 1955. Choi co-founded the Oh Do Kwan, and was made an honorary director and given an honorary 5th
dan ranking in the
Chung Do Kwan. Due to accusations of dishonesty, Choi was stripped of his rank and position in the Chung Do Kwan. ITF taekwondo organizations credit Choi with starting the spread of
taekwondo internationally by stationing Korean taekwondo instructors around the world, and have consistently claimed that ITF-style taekwondo is the only authentic style of taekwondo, most notably in early sections of its textbooks. He was also the author of the first English taekwondo syllabus book,
Taekwon-Do, published by Daeha Publication Company in 1965. In 1972, Choi went into exile in Canada after the South Korean government refused to allow his organisation to teach taekwondo in North Korea, and the South Korea government formed the World Taekwondo Federation (WTF) in 1973 == Death ==
