Read this post first: "Is the Okinawan System of Karate Representative of Japanese Budo?"
Now that you are up to date with my perceptions I can now say, "I was wrong!" In the new book, Karate 1.0 by Andreas Quast I have come to understand that Okinawan Systems of Karate may just be representative of the Okinawan versions of Japanese Budo. Much like the Japanese, the Okinawans had the tendency to take things of value from other cultures and absorb them into their own. This, apparently, includes Budo.
The Okinawans, it would seem, had a very militaristic way of life up to the early sixteen hundreds when the Satsuma Samurai took control of the security of its outer most territory, Okinawa or the LooChoo Islands.
I don't believe that modern karate as practiced in the 1900's and now this century are representative of Japanese Budo but I do believe historically that the influences are there. I really want to strongly suggest getting this book because it has blown a few holes in what "I believed" were a part of the legacy of Okinawan karate or Martial Arts.
