It seems the only thing that is certain is change, and martial arts aren't any different. Sure there are styles and techniques being taught in schools today all over the world that have been around for decades if not centuries, but there are times when some systems become more popular than others. Right now Brazilian Jiu-Jitsu (BJJ) is enjoying great popularity largely thanks to the popularity of mixed martial arts fighting competitions in the United States and other countries. Though the combat sport is popular many people don't realize that BJJ isn't Brazil's only contribution to combat sport.

Brazilian Jiu-Jitsu is probably Brazil's best known sport and rivals soccer in popularity there. The style traces its origins back to Mitsuyo Maeda a Japanese Judo practitioner who was traveling the world to promote cultural understanding and he did so by teaching Judo. Not long after arriving in Brazil in 1914 Maeda put on a martial arts expedition where he took on Brazilian boxers and wrestlers and defeated every competitor easily. Among those watching were members of the Gracie family who weren't satisfied to just watch the competition, they wanted to learn the new style.
