Early British settlers in America brought a strong wrestling tradition with them. The settlers also found wrestling to be popular among Native Americans. Amateur wrestling flourished throughout the early years of the North American colonies and served as a popular activity at country fairs, holiday celebrations, and in military exercises. The first organized national wrestling tournament took place in New York City in 1888. Wrestling has also been an event at every modern Olympic Games since the 1904 games in St. Louis, Missouri (a demonstration had been performed at the first modern Olympics). The international governing body for the sport, United World Wrestling (UWW), was established in 1912 in Antwerp, Belgium as the International Federation of Associated Wrestling Styles (FILA). The 1st NCAA Wrestling Championships were also held in 1912, in Ames, Iowa. USA Wrestling, located in Colorado Springs, Colorado, became the national governing body of U.S. amateur wrestling in 1983.
