Wrestling was on the programme at the first modern Olympics in 1896, and 1900 was the only year that wrestling did not feature on the programme at all. Both freestyle and Greco-Roman wrestling have been consistently contested at the Olympics since 1920. Prior to that (except in 1908), only one form was used, usually Greco-Roman. Today the dominant country in wrestling is Russia, especially in the Greco-Roman style. The United States is close to the Russians in freestyle, however. Other countries which produce top international wrestlers include Iran, Turkey and Mongolia, and wrestling is the national sport of these three nations. At the 2000 Games in Sydney the wrestling programme underwent a change. Since 1972, wrestling has had 10 classes in both freestyle and Greco-Roman, but during the Sydney Games only eight classes were contested in each style. The weights also changed slightly, and the lightest class, usually termed light-flyweight, has basically been eliminated. When the modern Olympic Games resumed in Athens in 1896, organisers considered wrestling so historically significant that it became a focus of the Games. They remembered tales of wrestling competition in 708 BC, of oiled bodies fighting on sand in the ancient Games. Greco-Roman wrestling was deemed a pure reincarnation of ancient Greek and Roman wrestling. Eight years later, Olympic officials added a second category with far less history and far less grandeur, but great popularity. Commonly known as "catch as catch can", freestyle wrestling had become the staple of 19th-century fairs and festivals in Great Britain and the United States, a form of professional entertainment. Like Greco-Roman wrestling, it became a staple of the Games themselves. In Greco-Roman competition, now dominated by Russia, wrestlers use only their arms and upper bodies to attack. In freestyle, where Olympic medallists in 1996 represented 17 different countries, wrestlers also use their legs and may hold opponents above or below the waist. Courtesy FILA
