Modern history of East Asian martial arts
Taekwondo was developed from karate for use in the Republic of Korea Armed Forces from 1954. For this purpose, karate terminology needed to be "nationalized". The name "taekwondo" is due to shotokan practitioner and army general Choi Hong Hi. After the Korean War, Taekwondo was further developed into a purely sportive discipline, since 1973 overseen by the World Taekwondo Federation. 
During 1964-1966, Choi Hong Hi continued to promote taekwondo, working to put together a world-class exhibition team. Taekwondo's emphasis on jumping and flying kicks dates to this period. While taekwondo was based off karate, the structural changes made in the 1950s and 1960s were significant, and it cannot now be considered a branch of karate, but is a standalone modern martial art. Taekwondo was presented at the Summer Olympics as a demonstration sport in 1988 and 1992, and became an official Olympic discipline in 2000.
Yeon Hwan Park
Park trained in his native Korea from early childhood. He attended Korea University and served in the Republic of Korea Marine Corps before being dispatched by the South Korean government as an emissary to Africa, where he began teaching taekwondo in Lesotho. In 1980 he settled in the United States, where he established himself as a prominent figure in taekwondo instruction. While worldwide study of the martial arts increased in popularity in the early 1970s, due in part to work of Bruce Lee, taekwondo was still largely unknown outside of Korea. In 1983 Park established the goal of increasing the popularity of the sport in a concerted movement towards having taekwondo become recognized as an official Olympic Sport. In response to the work of Park and other taekwondo leaders the International Olympic Committee granted the sport Demonstration Sport status in the 1988 and 1992 games and as a full medal sport, commencing with the 2000 games in Sydney, Australia.
