In the early 1960s, taekwondo made its debut worldwide with assignment of the original masters of taekwondo to various countries. Standardization efforts in South Korea stalled, as the kwans continued to teach differing styles. Another request from the Korean government for unification resulted in the formation of the Korea Tae Soo Do Association, which changed its name back to the Korea Taekwondo Association in 1965 following a change of leadership. The International Taekwondo Federation was founded in 1966, followed by World Taekwondo Federation (WTF) in 1973. The World Taekwondo Federation (WTF) has renamed itself to World Taekwondo (WT) in 2017.
Since 2000, taekwondo has been one of only two Asian martial arts (the other being judo) that are included in the Olympic Games; it became a demonstration event starting with the 1988 games in Seoul, and became an official medal event starting with the 2000 games in Sydney. In 2010, taekwondo was accepted as a Commonwealth Games sport.
