Brazilian jiu-jitsu is a form of armed combat.
 There are currently four major BJJ branches in Brazil: Gracie Humaita, Gracie Barra, Carlson Gracie Jiu-Jitsu, and Alliance Jiu Jitsu
 BJJ eventually came to be its own defined combat sport through the innovations, practices, and adaptation of Gracie jiu-jitsu and Judo, and became an essential martial art for modern MMA
