History of Brazilian Jiu Jitsu
Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport that focuses on grappling and especially ground fighting with the goal of gaining a dominant position and using joint-locks and chokeholds to force an opponent to submit. The system developed from a modified version of pre-World War II Judo known as Kosen Judo including some techniques from Japanese Jujutsu (most especially that of the Ryu known as Fusen Ryu and with a focus on ne-waza (ground technique). It promotes the principle that a smaller, weaker person using leverage and proper technique can successfully defend themselves against a bigger, stronger assailant. Jiu Jitsu can be trained for self defense, sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition. Sparring (commonly referred to as 'rolling') and live drilling play a major role.
Origin
The art began with Mitsuyo Maeda (aka Conde Koma, or Count Combat in English), a Japanese expert judoka and member of the Kodokan. Jigoro Kano sent Maeda overseas to spread his Judo to the world. Eventually, Maeda emigrated to Brazil in the 1910s where an influential businessman named Gastão Gracie helped him get established. In return for his aid, Maeda taught the fighting art to Gastão's son Carlos Gracie, who then taught the art to all of his brothers.
