Pekiti-Tirsia's movements are based on the traditional blade art of
arnis. Pekiti-Tirsia Kali specifically was derived from a family system that goes back at least four generations, starting with Norberto Tortal. It was further developed and improved during the years 1930-36 by his grandson Conrado Tortal. The system is now headed by Leo Gaje, the grandson of Conrado Tortal. Gaje introduced his system to North America as Pekiti-Tirsia Arnis after arriving in the US in 1972. The invented faux-native term Kali was adopted in later years in place of the Spanish-derived Arnis. His style earned recognition and respect from major martial arts organizations such as the Jewish
Karate Federation, the United States Karate Association International, and the United States Karate Federation. His system has been an influence on the Dog Brothers,
Dan Inosanto and other FMA practitioners. He has since brought the system to various European countries as well. In 1995, Pekiti Tirsia International was formed in the US. In 1997, this organization went its own way. It is currently headed by Bill McGrath (President and Chief Instructor). (Law Enforcement Director), Magino'o
Dan Inosanto (North American Director), Sifu Manfred Steiner (European Director), Ralf Beckmann (Director for Germany), and Roberto Bonomelli and Attilio Acquistapace (Co-Directors for Italy). In 1996, Pekiti-Tirsia Europe Organization was formed, with Uli Weidle as Managing Director. In the year 1997, the Centennial Celebration for 100 years of Pekiti-Tirsia was celebrated in Subic Bay, Zambales, Philippines on October 25, 1997. Pekiti-Tirsia was the only Filipino Martial Art officially recognized as having a centennial. In 2003, Pekiti Tirsia Global was established. PTKGO (Tim Waid) National Directors include Leo Gaje. and Rommel Tortal in the Philippines, Timothy D. Waid in the United States, Philip Gelinas in Canada, and Uli Weidle in Europe. == Fighting methods ==
