In spite of Korea's rich history of ancient and traditional martial arts,
Korean martial arts faded into obscurity during the Joseon Dynasty. Korean society became highly centralized under Korean Confucianism and martial arts were lowly regarded in a society whose ideals were epitomized by its scholar-kings. Remnants of traditional martial arts such as Subak and Taekyon were banned from practice by the general populace and reserved for sanctioned military uses although folk practice by the common populace still persisted into the 19th century. During the Japanese occupation (1910-1945),
the practice of taekyon was banned. Although practice of the art nearly vanished, Taekyon survived through underground teaching and folk custom. As the Japanese colonization established a firm foothold in Korea, the few Koreans who were able to attend Japanese universities were exposed to Okinawan and Japanese martial arts with some even receiving black belts under Gichin Funakoshi. Koreans in China were also exposed to Chinese martial arts. By 1945, when the Korean peninsula was liberated from Japanese colonization, many martial arts schools were formed and developed under various names such as Tang Soo Do reflecting foreign influence.
At the end of World War II, several Kwans arose. They were: Chung Do Kwan, Moo Duk Kwan, Jidokwan (or Yun Moo Kwan), Chang Moo Kwan, Han Moo Kwan, Oh Do Kwan, Jung Do Kwan, Kang Duk Won, and Song Moo Kwan.
