In 1924, the Guomindang (Chinese National Party) established the Whampoa Military Academy in Canton province, Southern China in order to train the Party’s leaders and create a modern military force.
In January 1923 they had formed a strategic alliance with the Soviet Union. The Academy utilised Soviet methods to establish party discipline, political instruction and training of military personnel.
Between 1904 and 1905 during the war between Russia and Japan, Russian forces experienced heavy losses with the Japanese in close quarter combat. They felt something had to be done and steps were taken to develop better methods of training soldiers for close quarter combat. The project was made official under the leadership of the Communist Party of the Soviet Union in 1917. The result of this project is what is today known as Sambo.
The Soviet military and the creators of Sambo felt a sport form was needed which could be safely practiced on a regular basis. This would also incorporate modern advancements in sports medicine and training methodology. All of which taught to them under the guidance of a skilled coach.
Under the tutelage of Soviet advisors, the Chinese endeavored to create a similar method of training their military forces. The program was perhaps more important to the Chinese who lacked an industrial base and access to most modern warfare technology.
The Whampoa military instructors who studied the traditional martial art styles combined them with the modern training methods and created Sanshou and
the decision was made to use a Kickboxing like format when practiced.
