Jidokwan is one of the original nine schools of the modern Korean martial arts that became Taekwondo and was founded in what is now South Korea at the end of World War II.

Jidokwan means "the Way of Wisdom School" with "ji" (지) = wisdom, "do" (도) = way and "kwan" (관) meaning either hall, school or institute, depending on context [citation needed].

The foundations of what was to eventually become Jidokwan were laid down by GM CHUN Sang Sup, who was one of the earliest Koreans to bring Japanese karate back to his homeland.

Upon GM Chun's return to his native Korea, he began teaching this fighting art at the Chosun Yun Moo Kwan school of Judo (朝鮮硏武館 拳法部), one of the few martial arts schools the Japanese occupying forces allowed to remain open during the period of their military occupation of that country.

GM Yoon eventually became a Shudokan karate "Shihan" (Sabum or teacher) under Kanken Tōyama Sensei while studying in Japan.

GM Yoon taught at GM Chun's Choson Yun Moo Kwan Kwon Bup Bu (권법무) for about six months before opening his own club, which he called the YMCA Kwon Bop Bu.

During the Korean War, all schools of martial arts were closed in Korea, including the Chosun Yun Moo Kwan.

Chun's former disciples voted Dr. Yun Kwae-byung, who had background as the director of the Kanbukan[2], as the first headmaster of Jidokwan.

Jidokwan was subsequently absorbed into the newly unified Korean system of Tae Kwon Do (Taekwondo), which translates as the Way of Foot and Fist, so that it ceased to exist as a distinct style of Korean "karate."

However, Jidokwan still exists in Korea today as a fraternal order which endorses the Kukkiwon martial arts system and supports World Taekwondo.

[3][4] Some have gone their own way, with many adopting taekwondo-like formats and methods while others have ranged farther afield (e.g., Nabi Su, a modern hybrid style that traces its roots back to the old 'Yun Moo Kwan' style although it's hardly recognizable as a form of traditional Korean karate today).
