Does anyone know of any good references covering the history of Jujitsu?
I've been studying Judo, Jujitsu (Japanese), and BJJ, and everyone I ask has a different version of the history of these arts. The internet doesn't help much either, so if anyone knows of a book that might be useful, that would be great.
I don't expect there to be a single definative version of this history, but I'd love to know more about it.
Seems to me there's a lot of cross fertilisation between Judo, Pre-Judo Jujitsu, Post-Judo Jujitsu, Aikido, and BJJ.
