Chun Kuk Do

Chun Kuk Do (Hangul: 천국도; Hanja: 天國道, commonly abbreviated as CKD) is a martial art (or type of fighting style) that Chuck Norris created. It is said to be based upon Tang Soo Do, another martial art. Chun Kuk Do was established in 1990. It is also known as the art of Chuck Norris as he was the most famous practitioner of this martial art.

Chun Kuk Do mainly means "The Universal Way," but has other meanings, such as, "The Way of 1000 Lands," or "The Way of Many Lands."

Chun Kuk Do has undergone many name changes, becoming known as Chun Kuk Do in the 1990s and most currently being called the Chuck Norris System.

Chun Kuk Do is an American hybrid martial arts style based on Traditional Taekwondo styles such as Tang Soo Do/Moo Duk Kwan Taekwondo.

Chunk Kuk Do is not an ad hoc collection of various techniques from different systems. Rather, it is a style with a deeply-rooted traditional foundation of its own – now unique and different from its Tang Soo Do predecessor – to which various other elements that complement its fundamentals have been added. Chun Kuk Do has come to emphasize self defense, competition, weapons, grappling, fitness, and more.”

Currently there aren't any other widely renowned fighters after the death of actor and martial artist Chuck Norris.
