During the period between the 8th and the 16th century, japanese history books teach us that civil wars were a common accurance in the lives of the citizens. this was the soul reason early forms of jiu jitsu were invented. The ongoing battles made it necessary for the samurai to be able to continue fighting their armoured opponents even if they had no blade available. One of the earliest mentions of the words jiu jitsu was in the year 1532, when a man called hisamori tenanuchi founded the first school in japan. The teachers had to keep the art a secret so not much is known about the techniques in these initial forms of the style.
the civil wars had become rare between the year 1603 and 1868, but the japanese continued to live their lives with one important phrase in mind : “Live in peace, but remember the war”. This is why it was considered that every citizen must have basic skills in self defense and so The martial art continued to spread and grow throughout japan.
