Brazilian Jiu Jitsu- BJJ

Brazilian Jiu-Jitsu is a martial art, combat sport and a self-defense system that focuses on grappling and especially ground fighting. The art was derived from the Japanese martial art of Kodokan judo in the early 20th century, which was itself developed from a number of schools (or Ryu) of Japanese jujutsu in the 19th century.It promotes the principle that a smaller, weaker person can successfully defend themself against a bigger, stronger assailant by using leverage and proper technique—most notably by applying joint-locks and chokeholds to defeat the other person. Brazilian Jiu Jitsu can be trained for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self-defense. Sparring (commonly referred to as 'rolling') and live drilling play a major role in training, and a premium is placed on performance, especially in competition.The art began with Mitsuyo Maeda (aka Conde Koma, or Count Coma in English), an expert Japanese judoka and member of the Kodokan. Maeda was one of five of the Kodokan's top groundwork experts that judo's founder Kano Jigoro sent overseas to spread his art to the world. Maeda left Japan in 1904 and visited a number of countries giving "jiu-do" demonstrations and accepting challenges from wrestlers, boxers, savate fighters and various other martial artists before eventually arriving in Brazil on November 14, 1914.

Maeda met an influential businessman named Gastão Gracie who helped him get established. In 1916, his 14 year-old son Carlos Gracie watched a demonstration by Maeda at the Teatro da Paz (Theatre of Peace) and decided to learn the art. Maeda accepted Carlos as a student, and Carlos went on to become a great exponent of the art and ultimately, with his younger brother Hélio Gracie became the founder of Gracie Jiu-Jitsu, modern Brazilian Jiu-Jitsu.

Jiu-Jitsu came to international prominence in the martial arts community in the 1990s, when Brazilian Jiu-Jitsu expert Royce Gracie won the first, second and fourth Ultimate Fighting Championships, which at the time were single elimination martial arts tournaments. Royce fought against often much-larger opponents who were practicing other styles, including boxing, shoot-fighting, karate, judo and tae kwon do. It has since become a staple art for many MMA fighters and is largely credited for bringing widespread attention to the importance of ground fighting. Sport BJJ tournaments continue to grow in popularity worldwide and have given rise to no-gi submission grappling tournaments, such as the ADCC Submission Wrestling World Championship.
