My primary system is not even 100 years old, so I teach all that I can about it specifically. I do, however, teach about the masters that taught our founder and how the different masters are or are not linked together. I also try to teach the history of the kata that we practise and what other styles also practise them. Since the Okinawan MA's are overlapping, so to speak, it is dificult to teach just one aspect of the history behind the formation of a particular style. I require my students to also have at least a small understanding of different historical figures that have made an impact on what and why we train.
