Description
The United States Karate Association (USKA) was the first karate organization on the mainland United States, founded by Robert Trias in 1948. The USKA became one of the largest associations of karate instructors in the nation, and through this organization Trias was also instrumental in setting up and promoting some of the first karate tournaments in the US in 1955, as well as national and worldwide competitions. The USKA rules for tournament competition are still used today in the United States with only slight variation.
