which martial arts was created from the principles of jiu jitsu
There are many variations of the art, which leads to a diversity of approaches. Jujutsu schools (ryū) may utilize all forms of grappling techniques to some degree (i.e. throwing, trapping, joint locks, holds, gouging, biting, disengagements, striking, and kicking). In addition to jujutsu, many schools teach the use of weapons. Today, jujutsu is practiced in both traditional and modern sports forms. Derived sport forms include the Olympic sport and martial art of judo, which was developed by Kanō Jigorō in the late 19th century from several traditional styles of jujutsu, and Brazilian jiu-jitsu, which was derived from earlier (pre -- World War II) versions of Kodokan judo.
