A tradition of combining wrestling and showmanship originates in 1830s France, when showmen presented wrestlers under names such as “Edward, the steel eater”, “Gustave d’Avignon, the bone wrecker”, or “Bonnet, the ox of the low Alps” and challenged members of the public to knock them down for 500 francs.[1]
In 1848, French showman, Jean Exbroyat formed the first modern wrestlers’ circus troupe and established a rule not to execute holds below the waist — a style he named "flat hand wrestling". This new style soon spread to the rest of Europe, the Austro-Hungarian Empire, Italy, Denmark and Russia under the names of Greco-Roman wrestling, Classic wrestling or French wrestling. By the end of the 19th century, this modern "Greco-Roman" wrestling style went on to become the most fashionable sport in Europe, and in 1898 the Frenchman Paul Pons, “the Colossus” became the first Professional World Champion
