Karate is a Japanese term, translated in modern times as "empty hand".  

In its most basic definition it is a method of fighting that has its roots in the martial disciplines of ancient India and China.  It incorporates myriad hand and foot blocks and strikes, as well as a variety of related fighting techniques that have evolved through the centuries into a virtual art form.  Karate has twisted and turned down the alleyways of time, influenced by each culture that it has touched, until the art we practice is often an amalgamation of techniques and philosophies from all over the world.
