I am doing an EPQ (Extended Project Qualification) in the UK, and I have chosen to write a dissertation on the origins of Okinawan Karate, and I was hoping that different history experts could assist me in doing so. For starters, I need to find some good sources, that can be cross-referenced to each other. So far, I have found a book called the Journal of Asian Martial Arts which provides some understanding on the impact of immigration on Karate. I have also managed to find this website: HISTORY OF OKINAWA KARATE However, I need more sources and I was hoping someone on here could provide me with something trustworthy? Next, I have to structure my question in the form where I must provide arguments and counter-arguments i.e. I have to debate myself and the different points I make within the dissertation. To do this, I must structure my question in a manner that will allow me to do so. I have drafted up a couple of questions, but I also would like some input on which would be the most convenient to tackle: To what extent did immigration and cultural assimilation* impact the origins of Okinawan Karate? To what extent did conflict and the ban on weapons affect the origins of Okinawan Karate? To which degree has eastern philosophy affected the development of Okinawan Karate? *: I could choose to talk about both, or one or the other Moreover, when referencing Okinawan Karate, should I refer to a specific style such as Shito-Ryu?
