Technically, 1955 signalled the beginning of Taekwon-Do as a formally recognized art in Korea. On the 11th of April 1955, a special board was summoned by General Choi to decide on the unified name of Taekwon-Do. After much debate, the five major Kwans, Chung Do Kwan, Oh Do Kwan, Song Moo Kwan, Chang Moo Kwan, Ji Do Kwan, and Moo Duk Kwan accepted the name because it closely resembled the name of the ancient Korean martial art, Tae Kyon. This single unified name of Taekwon-Do replaced the different and confusing terms, such as Dang Soo, Gong Soo, Taek Kyon, and Kwon Bup.
