Geo Omori opened the first Jujitsu / Judo school in Brazil in 1909. He would go on to teach a number of individuals including Luiz França. Later, Mitsuyo Maeda was one of five of the Kodokan's top groundwork (newaza) experts that judo's founder Kano Jigoro sent overseas to demonstrate and spread his art to the world. Maeda had trained first in sumo as a teenager, and after the interest generated by stories about the success of Kodokan Judo at contests with other jujutsu schools that were occurring at the time, became a student of Jigoro Kano. Maeda left Japan in 1904 and visited a number of countries giving "jiu-do" demonstrations and accepting challenges from wrestlers, boxers, savate fighters and various other martial artists before eventually arriving in Brazil on November 14, 1914.
Gastão Gracie was a business partner of the American Circus in Belém. In 1916, Italian Argentine circus Queirolo Brothers staged shows there and presented Maeda. In 1917, Carlos Gracie, the eldest son of Gastão Gracie, watched a demonstration by Maeda at the Da Paz Theatre and decided to learn judo. Maeda accepted Carlos as a student and Carlos learned for a few years, eventually passing his knowledge on to his brothers. Sibling Hélio Gracie gradually further developed Gracie Jiu Jitsu as a softer, pragmatic adaptation from judo that focused on ground fighting, as he was unable to perform many judo moves that require direct opposition to an opponent's strength.
Although the Gracie family is typically synonymous with BJJ, another prominent lineage started from Maeda via another Brazilian disciple, Luiz França. This lineage had been represented particularly by Oswaldo Fadda. Fadda and his students were famous for influential use of footlocks and the lineage still survives through Fadda's links with today's teams such as Nova União and Grappling Fight Team. The art is sometimes referred to as Gracie Jiu-Jitsu (GJJ), this name was trademarked by Rorion Gracie, but after a legal dispute with his cousin Carley Gracie, his trademark to the name was voided. Other members of the Gracie family often call their style by personalized names, such as Charles Gracie Jiu-Jitsu or Renzo Gracie Jiu-Jitsu, and similarly, the Machado family call their style Machado Jiu-Jitsu (MJJ). While each style and its instructors have their own unique aspects, they are all basic variations of Brazilian jiu-jitsu. Today there are four major branches of BJJ from Brazil: Gracie Humaita, Gracie Barra, Carlson Gracie Jiu-Jitsu and Alliance Jiu Jitsu. Each branch can trace its roots back to Mitsuyo Maeda via the Gracie family or Oswaldo Fadda.
