BJJ is a martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting. Luiz França and Carlos Gracie are learnt to be the forerunners of BJJ taught by master Mitsuyo Maeda. Brazilian jiu-jitsu eventually came to be its own art through the experimentations, practices, and adaptation from the Judo knowledge of Carlos and Hélio Gracie, who then passed their knowledge on to their extended family.

BJJ promotes the concept that a smaller, weaker person can successfully defend against a bigger, stronger assailant by using proper technique, leverage, and most notably, taking the fight to the ground, and then applying joint-locks and chokeholds to defeat the other person. BJJ training can be used for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self-defense.
