taekwondo1-7, Exercise 2: Hapkido's sources

Model answer:

Technical sources (Hapkido article): adapted from Daito-ryu Aiki-jujutsu as taught by Choi Yong-sool after he returned to Korea following about 30 years in Japan; his disciples combined it with kicking and striking techniques of indigenous and contemporary arts such as Taekkyon and Tang Soo Do, and with throwing and ground-fighting techniques from Japanese judo. The Korean martial arts article adds that early development by different instructors left hapkido with no single standard curriculum.

Contested: Choi Yong-sool's training. In a 1980 interview he claimed to have been adopted by Takeda Sokaku at age 11 and to have trained with him for 30 years. The article says other claims say he was a worker in the Takeda home, that the enrolment records of Takeda's son do not seem to include his name, and that apart from Choi's own claims there is little evidence of an adoption. It also reports a register page released by the current head of the main Daito-ryu line that contains his name, and some scholars' view that most of his training came from Yoshida Kotaro.

Agreed: Choi brought Daito-ryu-type techniques to Korea after the war, and hapkido grew from them through his students.
