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).
World Wrestling Championships
The Men's Greco-Roman Wrestling tournament began in 1904, and the Men's Freestyle Wrestling tournament began in 1951. The Women's Freestyle championships were first staged in 1987.
