The umbrella term traditional taekwondo typically refers to the martial arts practiced by the kwans during the 1940s and 1950s, though in reality the term "taekwondo" had not yet been coined at that time, and indeed each kwan was practicing their own unique style of martial art. During this timeframe taekwondo was also adopted for use by the South Korean military, which only served to increase its popularity among civilian martial arts schools.
