History
Brazilian jiu-jitsu (BJJ) was developed after Mitsuyo Maeda brought judo to Brazil in 1914. Maeda agreed to teach the art to Luiz França, Jacintho Ferro and Carlos Gracie, son of his friend, businessman and politician Gastão Gracie. Luiz França went on to teach it to Oswaldo Fadda. After Carlos learned the art from Ferro and Maeda, he passed his knowledge to his brothers Oswaldo, Gastão Jr., and George. Meanwhile, Hélio Gracie would peek in and practice the techniques, although he was told he was too young to practice. At the time, judo was still commonly called Kanō jiu-jitsu (from its founder Kanō Jigorō), which is why this derivative of judo is called Brazilian jiu-jitsu rather than Brazilian judo.
Its emphasis shifted to ground grappling because the Gracie family thought it was more efficient and much more practical. Carlos and Helio helped the development by promoting fights (mostly against practitioners of other martial arts), competitions and experimenting throughout decades of intense training. BJJ dominated the first large modern mixed martial arts competitions in the United States, causing the emerging field to adopt many of its practices. Less-practiced stand-up techniques in Gracie Jiu Jitsu survive from its judo and jujutsu heritage (knife defense, gun defense, throws, blocking, striking etc.).
