Brazilian Jiu-Jitsu (BJJ/Gracie Jiu-Jitsu) is a martial art and combat sport that focuses on grappling and especially ground fighting. It is a derivative of early 20th century Kodokan Judo, which was itself then a recently-developed system (founded in 1882), based on multiple schools (or Ryu) of Japanese jujutsu.
Like judo, it promotes the principle that smaller, weaker person can successfully defend themselves against a bigger, stronger assailant using leverage and proper technique; applying joint-locks and chokeholds to defeat them. BJJ 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 in training, and a premium is placed on performance, especially in competition.
