As early as the Greek civilization in the west and the Chinese civilization in the east, the value of military training and education had been emphasized. In the earliest Peloponnesian war, Athens recognized the dominance of Sparta in military conflict because of its military readiness and caught up with the warlike city-state. Even in the Sino classic The Art of War, there is an account of court ladies being beheaded because they did not take military training seriously despite the protests of the emperor to which they belong.
