Brief history of arnis​

Arnis was developed by the indigenous populations of the Philippines, who used an assorted range of weaponry for combat and self-defense. ... Just over a century later, in 2009, the government of the Philippines declared arnis to be the martial art and national sport of the Philippines.

The origin of Arnis can be traced back to native fighting techniques during conflicts among the various Prehispanic Filipino tribes or kingdoms, though the current form has Spanish influence from old fencing which originated in Spain in the 15th century.
