With the possible exception of athletics, wrestling is recognised as the world’s oldest competitive sport. Indeed, cave drawings of wrestlers have been found dating as far back as 3,000 BC. The sport was introduced into the ancient Olympics in 708 BC, shortly after the Games' recorded history began.
Greco vs. Freestyle
In Greco-Roman wrestling, the wrestlers use only their arms and upper bodies to attack, and can only hold those same parts of their opponents. As the name suggests, freestyle is a much more open form in which wrestlers also use their legs and may hold opponents above or below the waist.
In Greco-Roman wrestling, arguably the oldest competitive sport in the world, competitors use only their arms and upper bodies to attack. When the modern Olympic Games resumed in Athens in 1896, wrestling became a focus of the Games. This was because organisers considered it historically significant; indeed Greco-Roman wrestling was deemed a pure reincarnation of ancient Greek and Roman wrestling.
