It contains stand-up maneuvers, but it is most famous for its devastating ground-fighting techniques.

Brazilian jiu-jitsu roots began in the early 1900s. Esai Maeda, the chief of a Japanese immigration colony who was assigned to Brazil, befriended Gastao Gracie. Maeda, a former jiu-jitsu champion in Japan, taught the art to Gracies son, Carlos. In 1925, Carlos and his four brothers opened the first jiu-jitsuschool in Brazil. Carlos younger brother, Helio, adjusted the techniques to suit his small frame, and thereby created Brazilian jiu-jitsu. In the early 80s, Helios son, Rorion, planted the seeds of BJJ in the United States, where the art has become immensely popular.
