Tolong jelaskan mengenai Sejarah dari Piala FA Korea

Turnamen Sepak bola Seluruh Korea dibetuk oleh Dewan Olahraga Korea pada 1921, pada saat masa penjajahan Jepang di Korea. Klub-klub sepak bola pemuda, pelajar, dan dewasa dari berbagai provinsi berpartisipasi. Setelah 1934, menjadi bagian dari Festival Olahraga Nasional Korea, which was the championship for various sports games and matched Koreans against other sports championships operated by Japanese who lived in Korea. The Korea Sports Council was disbanded in 1937, due to the Japanese government's oppression. The KFA succeeded it after 1938, but was cancelled after 1940 for the same reason during Perang Dunia II.

Setelah pembebasan Korea, the KFA founded the National Football Championship in 1946. Many clubs from all over Korea participated. It opened in late autumn, like its predecessor, the All Korea Football Tournament.

It declined after the founding of the The Korean Professional Football League (K-League) in 1983, because professional clubs and famous players didn’t take part in it. There were several efforts to make professional clubs join the tournament, and it became so successful that many top-rank clubs joined in and the KFA renamed it FA Cup for the 1988 and 1989 seasons. However, it soon returned to an amateur tournament, because of discord between the KFA and professional football clubs. KFA's FA Cup separated from the National Football Championship in 1996. The two competitions merged again in 2000.
