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).
