Silat is a collective word for the indigenous martial arts from Malaysia, Indonesia and South East Asia. There are hundreds of different styles that vary per by individual as well as island and village. Silat is often thought of just as a weapons or blade art, but in fact it has a wide variety of techniques that include empty hand strikes, grappling, joint manipulation and bladed weaponry. Silat utilizes some unorthodox grappling techniques that look very similar to ones found in Indochinese martial arts. Many people believe that Silat's origins are influenced by India and China, while others theorize that Silat is an amalgamation of styles, culture and influences. We do know that Silat arose out of hunting methods and military training by the region's native inhabitants.
