グレイシー一族
Vale tudo began in the 1920s and became renowned through its association with the "Gracie challenge", which was issued by Carlos Gracie and Hélio Gracie and upheld later by descendants of the Gracie family. The "Gracie Challenges" were held in the garages and gyms of the Gracie family members. When the popularity grew, these types of mixed bouts were a staple attraction at the carnivals in Brazil.
