Karate at the Summer Olympics
In September 2015, karate was included in a shortlist along with baseball, softball, skateboarding, surfing, and sport climbing to be considered for inclusion in the 2020 Summer Olympics; and in June 2016, the Executive Board of the International Olympic Committee (IOC) announced that they would support the proposal to include all of the shortlisted sports in the 2020 Games. Finally, on August 3, 2016, all five sports (counting baseball and softball together as one sport) were approved for inclusion in the 2020 Olympic program.
Karate
Karate began as a common fighting system known as "te" (Okinawan: ti) among the Pechin class of the Ryukyuans. After trade relationships were established with the Ming dynasty of China in 1372 by King Satto of Chūzan, some forms of Chinese martial arts were introduced to the Ryukyu Islands by the visitors from China, particularly Fujian Province. A large group of Chinese families moved to Okinawa around 1392 for the purpose of cultural exchange, where they established the community of Kumemura and shared their knowledge of a wide variety of Chinese arts and sciences, including the Chinese martial arts. The political centralization of Okinawa by King Shō Hashi in 1429 and the policy of banning weapons by King Shō Shin in 1477, later enforced in Okinawa after the invasion by the Shimazu clan in 1609, are also factors that furthered the development of unarmed combat techniques in Okinawa.
