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 in the Philippines
Taekwondo was introduced to the Philippines through the efforts of Kim Bok Man and Young Man Park. Grand Master Bok Man Kim arrived in 1970 to continue Park's legacy of propagating Taekwondo upon the invitation of President Marcos. Bok Man Kim continued to pioneer Taekwondo worldwide and left the Philippines in 1971. In 1975, Sung-Chon Hong came to the Philippines to continue to introduce Taekwondo again. The Philippine Taekwondo Association (PTA) has been established by Grand Master Sung-Chon Hong. The current Central Headquarters of the PTA is at the Rizal Memorial Sports Complex. The PTA is a member of the Kukkiwon, World Taekwondo Federation, Philippine Sports Commission, Philippine Olympic Committee and Asian Taekwondo Union. Sung-Chon Hong has devoted decades to mentoring, developing and promoting Taekwondo nationwide and worldwide, and is popularly considered the Father of Taekwondo in the Philippines.
