Arnis, also known as Kali or Eskrima, is the national sport and martial art of the Philippines.The three are roughly interchangeable umbrella terms for the traditional martial arts of the Philippines ("Filipino Martial Arts", or FMA), which emphasize weapon-based fighting with sticks, knives, bladed weapons, and various improvised weapons, as well as "open hand" or techniques without weapons. It is also known as Estoque (Spanish for rapier), Estocada (Spanish for thrust or stab) and Garrote (Spanish for club). In Luzon it may go by the name of Arnis de Mano.
The indigenous martial art that the Spanish encountered in 1610 was not yet called "Eskrima" at that time. During those times, this martial art was known as Paccalicali-t (pronounced as pakkali-kalî) to the Ibanags, Didya (later changed to Kabaroan) to the Ilokanos, Sitbatan or Kalirongan to Pangasinenses, Sinawali ("to weave") to the Kapampangans, Calis or Pananandata ("use of weapons") to the Tagalogs, Pagaradman to the Ilonggos and Kaliradman to the Cebuanos. Kuntaw and Silat are separate martial arts that are also practised in the Philippine Archipelago.
There have been campaigns for arnis to be nominated in the UNESCO Intangible Cultural Heritage Lists, along with other Philippine martial arts. As of 2018, UNESCO has inscribed 9 martial-arts–related intangible heritage.
