The nations at the 1912 Games entered a total of 267 wrestlers, although the actual competitors who appeared in Sweden were fewer, with 171 actually turning up to compete. Greco-Roman wrestling was the only style of wrestling competed for at the Games. The bouts took place in the open air in an area of the Olympic stadium, with the wrestlers split according to weight into five divisions: featherweight, lightweight, middleweight A (later referred to as middleweight), middleweight B (later referred to as light heavyweight) and heavyweight.
