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.
Taekwondo
The term "traditional taekwondo" typically refers to martial arts practised in Korea during the 1940s and 1950s by the nine original kwans, or martial arts schools, after the conclusion of the Japanese occupation of Korea at the end of World War II. The term "taekwondo" had not yet been coined, and in reality, each of the nine original kwans practised its own style of martial arts. The term "traditional taekwondo" serves mostly as an umbrella term for these various styles, as they themselves used various other names such as Tang Soo Do (Chinese Hand Way), Kong Soo Do (Empty Hand Way) and Tae Soo Do (Foot Hand Way). Traditional Taekwondo is still practised today but generally under other names, such as Tang Soo Do and Soo Bahk Do.
