Karate in the U.S.
In late 1945, shortly before Trias left the Navy in January of the following year, he began teaching martial arts in his backyard. He later opened the first public karate school operated by a Caucasian in the United States mainland in
Phoenix, Arizona, in 1946. Trias served as an officer of the Arizona State Highway Patrol from 1946 to 1961 utilizing his self-defense knowledge on duty and teaching his fellow officers. In 1948 he founded the
United States Karate Association (USKA), the first karate organization on the American mainland. Jointly with
John Keehan, Trias hosted the first national karate tournament in the United States, called the 1st World Karate Tournament, at the
University of Chicago Fieldhouse in late July 1963 in
Chicago, IL. This event was re-titled the USKA Nationals in 1966 and the USKA Grand Nationals in 1968. His rules for tournament competition are still used today with only slight variation. Trias' style was once dubbed, by Trias himself, as Shuri Karate Kenpo, Goju-Shorei-Ryu, and Shorei-
Goju ryu though there is no relationship or direct ancestry to the Goju-Ryu currently practiced in
Okinawa or the original form of Shorei-ryu once practiced by the Okinawans. His style is now referred to as Shuri-ryu to imply roots to traditional karate though his style is much different from any martial art originating from the Okinawan islands. It has much more Chinese influence and overtones than Okinawan. The naming of his style was as eclectic as the style itself. A few US organizations claim to trace their roots to him and the USKA, including the United States Karate-Do Kai, Professional Karate Commission, United States Karate Alliance, International Shuri-Ryu Association, and Kondo No Shokai. ==Career accomplishments==
