Brazilian Jiu-Jitsu (BJJ) was founded and
developed by the Gracie Family. Its roots are derived from several
sources, including pre-war Kodokan Judo and western wrestling. An
aim of BJJ is to bring an opponent to the ground and then use
grappling techniques to cause a submission. It is an excellent form
of self-defense, and is used in MMA and Vale Tudo competitions,
such as UFC and the now defunct Pride FC.
