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).
Wrestling at the 2016 Summer Olympics
Around 344 wrestlers competed in 18 events at the 2016 Summer Olympics. In September 2013, a new change to the rules and guidelines of the sport had been instituted and overhauled by the International Olympic Committee and FILA (now known as the United World Wrestling). A single Olympic weight class was removed each from the men's freestyle and Greco-Roman wrestling to add two more weights for the women. Other changes in wrestling at these Games also featured a single-round tournament within a six-minute limit, instead of two-round or tiebreaker.
