refers to ancient and newer fighting methods devised in the Philippines. It incorporates elements from both Western and Eastern Martial Arts. The intrinsic need for self-preservation was the genesis of these systems. Throughout the ages, invaders and evolving local conflict imposed new dynamics for combat in the islands now making up the Philippines. The Filipino people developed battle skills as a direct result of an appreciation of their ever-changing circumstances. They learned often out of necessity how to prioritize, allocate and use common resources in combative situations. Filipinos have been heavily influenced by a phenomenon of cultural and linguistic mixture. Some of the specific mechanisms responsible for cultural and martial change extended from phenomena such as war, political and social systems, technology, trade and of course, simple practicality.
