Robert A. Trias (1923–1989) was a U.S. karate pioneer, founding the first karate school in the mainland United States.[1] He also developed Shuri-ryū karate, an eclectic style with roots in the Okinawan Shuri-te tradition.

Life before karate[edit]

Trias was employed by Southern Pacific Company as a boilermaker apprentice from 1937–39 and a boilermaker from 1939-42.

Introduction to karate[edit]

While serving in the United States Naval Reserve as a Metalsmith First Class (M1c) during World War II, Robert Trias was stationed on or around Tulagi in the Solomon Islands from June 1944 to November 1945, and was a Navy champion middleweight boxer. There he met Tung Gee Hsiang, a Chinese missionary of Chan (Zen) Buddhism. Hsiang often watched Trias work out and imitated his boxing footwork, and he asked to practice with Trias. Trias refused because Hsiang was "just a tiny little guy," but Hsiang was persistent and at last Trias agreed to spar with him. Hsiang gave Trias "the biggest thrashing of his life" and Trias then asked Hsiang to instruct him in the martial arts.[2]

Hsiang taught Trias some xingyiquan as well as some Okinawan Shuri-Te karate, which Hsiang had learned from Choki Motobu in Okinawa. Later, Trias studied with Hoy Yuan Ping whose lineage was from the Teshin Shinjo School of Kempo Jujutsu in Japan. Trias also held a 6th dan black belt in Kodokan Judo,[citation needed] and studied under Yaju Yamada. Trias was also mentored by Yasuhiro Konishi and Makoto Gima.

Karate in the U.S.[edit]

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 karate school in the United States mainland in Phoenix, Arizona in 1946. Trias served as an officer of the Arizona State Highway Patrol from 1946-1961[3] 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 US mainland.[4][5] Through his pioneering efforts in Karate, he became the United States' liaison with Korea, Japan, China, and Okinawa for many years. Jointly with John Keehan, Trias hosted the first actual national karate tournament, called the 1st World Karate Tournament, at the University of Chicago Fieldhouse in 1963 in Chicago, IL. This event was retitled the USKA Nationals in 1966 and the USKA Grand Nationals in 1968.[4] His rules for tournament competition are still used today with only slight variation.

Trias' style was known as Shorei-Goju ryu, Shorei-ryu and Shuri-ryu. Many 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.

Death and legacy[edit]

Trias died of cancer on July 11, 1989, leaving the Shuri-ryu system to his daughter Roberta Trias-Kelley, inheritor and Menkyo Kaiden of Shuri-Ryu. This precipitated a struggle for succession within the USKA.[8] Trias is buried in Section 35, Site 112 of the National Memorial Cemetery of Arizona in Phoenix.
