Where was Brazilian Jiu-Jitsu founded?

Brazilian Jiu-Jitsu originated in Japan and was brought to Brazil by Mitsuo Maeda in 1914. Maeda trained Carlos and Helio Gracie, who tested and refined Jiu-Jitsu to be what it is today. Jiu-Jitsu continued to evolve over the years, eventually incorporating aspects of wrestling and other grappling arts into the curriculum. Rorion Gracie, Helios' son, brought Jiu-Jitsu to the United States in the 1970's.
