The period of Japanese history between the 8th and 16th centuries was covered with constant civil war and many systems of Jiu-Jitsu were utilized, practiced and perfected on the battlefield. This training was used to conquer armored and armed opponents.
It was originally an art designed for warfare, but after the abolition of the Feudal system in Japan, certain modifications needed to be made to the art in order to make it suitable for practice. During Feudal times, Jiu-Jitsu was also known as Yawara, Hakuda, Kogusoko, and an assortment of other names.
The earliest recorded use of the word “Jiu-Jitsu” happens in 1532 and is coined by Hisamori Tenenuchi when he officially established the first school of Jiu-Jitsu in Japan. The history of the art during this time is uncertain because teachers kept everything secret.
In approximately 1603, Japan came to a fairly peaceful period following the formation of the Tokugawa military government by Tokugawa Ieyasu. During this time (1603-1868), the feudal civil wars that had plagued Japan for centuries started to disappear. However, following the adage “living in peace, but remembering war,” the traditions of classical budo (martial arts) required that everyone should learn a method of self-defense for those situations where weapons could not be used and the practice of Jiu-Jitsu continued to spread. Forms and techniques displaying weapons skills of fighting began to yield to weaponless styles which incorporated many of the grappling ground fighting techniques of the older styles.
After the Feudal period in Japan ended, a way to practice the art and compete with safer rules was needed, which is why Jigoro Kano (1860-1938), an educated man and member of the Cultural department and a practitioner of Jiu-Jitsu, developed his own version of Jiu-Jitsu in the late 1800s, called Judo. Jigoro Kano devised a new system for physical culture and moral training as well as for winning contests.
