After World War II, members of the US military learned karate in Okinawa or Japan and then opened schools in the USA.
In 1945 Robert Trias opened the first dojo in the United States in Phoenix, Arizona, a Shuri-ryū karate dojo. In the 1950s, Edward Kaloudis, William Dometrich (Chitō-ryū), Ed Parker (Kenpo), Cecil Patterson (Wadō-ryū), Gordon Doversola (Okinawa-te), Louis Kowlowski, Don Nagle (Isshin-ryū), George Mattson (Uechi-ryū), Paul Arel (Sankata, Kyokushin, and Kokondo) and Peter Urban (Gōjū-kai) all began instructing in the US.
