 Wrestling as a modern sport developed in the 19th century out of traditions of folk wrestling, emerging in the form of two styles of regulated competitive sport, "freestyle" and "Greco-Roman" wrestling (based on British and continental tradition, respectively), summarized under the term "amateur wrestling" by the beginning of the modern Olympics in 1896.The separation of "worked", i.e.purely performative, choreographed wrestling ("admitted fakery" or "kayfabe") from competitive sport begins in the 1920s.
