The Korea Baduk Association, also known as Hanguk Kiwon (Hangul: 한국기원) was founded in November 1945 by Cho Namchul. Baduk is a game which was present in Korea by the 5th century. It originated in China, but the West is more familiar with the Japanese name Go. This is because the Japanese were the first to introduce it to the west. Japan was introduced to the game in the 7th century AD. The Hanguk Kiwon is the Go organization that oversees go professionals in South Korea. It issues official diplomas for strong players and organizes tournaments for professionals.
