Since we started with B, let's backtrack to A shall we?
(Escrima or Kali)
Arnis was developed by the settlers of the Philippine Islands, many of them from China, India, Indonesia, and Southwest Asia. When the Spanish invaded the islands, they dubbed the fierce stick-fighting style of the natives “Escrima,” which means “skirmish.” After conquering the island, the Spanish outlawed the style, and it was forced underground. The style was preserved through dances and mock battles, in which the natives played the role of Spaniards, wearing the “arnes,” or medieval armor. These plays used the same footwork as Escrima and kept the techniques alive.
Remy Amador Presas, who incorporated empty-hand techniques, such as kicks and throws, into the style to make it more rounded, and who blended more than 7,000 regional styles into one national style, is considered the founder of Modern Arnis. This updated style also has a mystical side—dubbed “The Flow” by Presas himself—which encourages each student to tailor the style to his body and natural movements rather than conform himself to the style. Arnis stylists refer to their greatest practitioners as “Grand Masters.”
