The introduction of jiu-jitsu to Brazil is largely credited to one Mitsuyo Maeda, who immigrated to Brazil in the 1920's and taught jiu-jitsu to Carlos Gracie of Rio de Janeiro (more on the Gracies later). The large number of Japanese immigrants to South America ensured that traditional Japanese martial arts, including ju-jitsu, would find a home in Latin America. However, Brazilian jiu-jitsu evolved into its own distinct style, incorporating techniques honed in the rough favelas (shantytowns) of the big cities.

Brazilian jiu-jitsu emphasizes ground fighting, in fact most Brazilian jiu-jitsu stylists want to take the fight to the ground, as opposed to the stand-up fighting of other fighting arts. Brazilian jiu-jitsu practitioners believe that most fights end up on the ground, so you'd might as well learn the most effective ground fighting techniques available.

These techniques include the aptly named guard and mount. While these two techniques seem very simple, they form the foundation for almost all other Brazilian jiu-jitsu techniques.

Brazilian jiu-jitsu really caught on with the advent of the Ultimate Fighting Championship (UFC) in 1993. The UFC, promoted by the Helio Gracie clan, was billed as the first tournament to pit practitioners of various martial arts styles against each other in an almost-no-holds-barred setting. The fact that Helio's son Royce won three of the first four tournaments using his family's brand of jiu-jitsu certainly cemented Brazilian jiu-jitsu as an art demanding serious consideration. After almost 20 tournaments, the UFC has become a huge moneymaker, with cable pay-per-view revenues and fighting personalities rivaling those in professional wrestling.

No description of Brazilian jiu-jitsu is complete without mentioning the Gracie family. Carlos Gracie, after learning jiu-jitsu from Maeda, taught the art to his brothers Osvaldo, Gastão, Jorge, and Helio. The Gracie family, through challenge matches, televised tournaments, and sheer numbers, have spread their namesake style throughout the world.
