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.
Korean martial arts
Traditional Korean martial arts gradually fell into three main groups or branches:
In 1958, these branches of traditional Korean martial arts were organized to form a single modern hybrid-system known as Kuk Sool Won. Today, Korean martial arts are being practiced worldwide; more than one in a hundred of the world's population practices some form of taekwondo. Among the best recognized Korean practices using weapons are traditional Korean archery and Kumdo, the Korean adaptation of the Japanese Kendo. The best known unarmed Korean Martial Arts Taekwondo and Hapkido though such traditional practices such as ssireum - Korean Wrestling - and taekkyeon - Korean Foot Fighting - are rapidly gaining in popularity both inside and outside the country.
