Hapkido and Aikido both share the same roots in Daito-Ryu Aikijujutsu as taught by Sokaku Takeda (1859 – 1943)
Daito-Ryu Aikijujutsu was founded in Japan during the 11th century by Minamoto Yoshimitsu.
As a child during the Japanese Occupation of Korea, Grandmaster Choi, Yong Sul (1904 – 1986), was taken to Japan where, as a house servant, he studied under Sokaku Takeda for some 30 years before returning to Korea and becoming the founder Hapkido along with Grandmaster Ji, Han Jae.
Another famous student of Sokaku Takeda was Morihei Ueshiba (1883 – 1969), the Founder of Akikido. Both Martial Arts share many of the same empty hand techniques while native history and culture have provided differences to the development and founding of these two distinct Arts .
The United States Martial Arts Association (USMAA) was created by Philip Porter in 1995. O-Sensei Porter continued to be the cornerstone of the association until August, 2011. The USMAA continues in the same spirit as outlined by O-Sensei Porter. The leaders of the association are dedicated martial artists who have incorporated the principles of Budo into their lives. The association is accepting of all martial arts styles, advocates fair and equitable ranks, and continues to provide the best training and leadership available. The association is a non-profit corporation.
