History of Belts and Ranks
by Wendell E. Wilson (2010)
Modern-day students of karate generally assume that the ranking system of kyu (color belt) and dan (black belt) levels, and the various titles that high-ranking black belts hold, are, like the katas, a part of karate tradition extending back centuries. However, despite the fact that karate is indeed very old, the ranking system itself dates back only to the early 20th century. A look at the history and development of the current rank system will help us to put our own belt ranks in proper historical perspective.
