History of wrestling
When the First Modern Olympic Games held in Athens in 1896, Greco-Roman wrestling was introduced as an Olympic discipline. After not being featured in the 1900 Olympics, sports wrestling was seen again in 1904 in St. Louis; this time in freestyle competition. Since then, Greco-Roman and freestyle wrestling have both been featured (with women's freestyle added in the Summer Olympics of 2004).
Freestyle wrestling
Since 1921, the International Federation of Associated Wrestling Styles (FILA), which has its headquarters near Lausanne, Switzerland, has set the "Rules of the Game", with regulations for scoring and procedures that govern tournaments such as the World Games and the competition at the Summer Olympics. These were later adopted by the Amateur Athletic Union (AAU) for its freestyle matches. Freestyle wrestling gained great popularity in the United States after the Civil War. By the 1880s, tournaments drew hundreds of wrestlers. The rise of cities, increased industrialization, and the closing of the frontier provided the affable environment for amateur wrestling, along with boxing, to increase in esteem and popularity. Amateur wrestling teams soon emerged, such as the wrestling team of the New York Athletic Club, which had its first tournament in 1878. Professional wrestling also developed, and by the 1870s, professional championship matches offered allowances of up to $1,000.
