basically people all went off in their own way, creating different kinds of karate, they pretty much just rivaling families that all think that they can do it better than everyone else... i study Chito Ryu, which branched off from another form of karate... i dont have my student manual with me right now... but i will take the time to put the "karate family tree" of how most variations branched off eachother... i will just skan the img soon, i dont feel like getting the manual now.
