Karate is one of the most widely practiced martial art forms in the world. Martial arts rely on acute physical coordination and mental focus. They were developed in Asia (primarily India, China and Japan) over the course of several thousands of years. In all this time, there have been countless martial arts variations, and there are hundreds of disciplines practiced today.
Modern karate developed out of martial arts forms practiced in Okinawa, an island that is now part of Japan. For hundreds of years, Okinawan martial arts experts honed a variety of combat styles, in part due to the political situation in the area. From time to time, the ruling authorities would ban peasants from possessing any weapons, leaving them with only their own bodies and household items to protect themselves.
