Origins: Samurai Unarmed Combat
Jiu-Jitsu developed in feudal Japan as the unarmed combat system of the samurai class. On a battlefield where a warrior might lose his sword or spear, he needed an effective system to fight armoured opponents at close range. Strikes to hard armour were ineffective - so Jiu-Jitsu emphasised throwing, joint manipulation and choking to incapacitate opponents.
Hundreds of distinct schools (ryu) developed across Japan, each with their own techniques and philosophy. Major historical schools include Takenouchi-ryu (considered one of the oldest, founded c.1532), Shindo Yoshin-ryu, Tenjin Shinyo-ryu and Kito-ryu - the latter two being the primary influences on Jigoro Kano when he created Judo in 1882.
The Meiji Era and Jiu-Jitsu's Decline in Japan
When Japan modernised during the Meiji Restoration (1868), the samurai class was abolished and traditional martial arts fell out of official favour. Jiu-Jitsu masters emigrated en masse, spreading the art worldwide. Kano's Judo absorbed the most practical techniques and became the dominant Japanese grappling art - but traditional Jiu-Jitsu lived on, most dramatically in Brazil.
Mitsuyo Maeda and the Brazilian Connection
Mitsuyo Maeda - known as 'Count Koma' - was a Judo champion under Kano who travelled the world from 1904 onward, fighting challenge matches across Europe, the United States, Cuba and finally Brazil. Maeda was a pragmatist who combined traditional Jiu-Jitsu ground techniques with his Judo, making him one of the most complete grapplers of his era.
When Maeda settled in Belem in 1914 and began teaching the Gracie family, he handed them the keys to what would become Brazilian Jiu-Jitsu. The Gracies refined and adapted his teachings into a new art - but the DNA is Japanese Jiu-Jitsu all the way through.
