Wrestling represents one of the oldest forms of combat. The origins of wrestling go back 15,000 years through cave drawings.
Babylonian and Egyptian reliefs show wrestlers using most of the holds known in the present-day sport. In ancient Greece wrestling occupied a prominent place in legend and literature; wrestling competition, brutal in many aspects, served as the focal sport of the ancient Olympic Games.
Greco-Roman wrestling and contemporary freestyle wrestling were soon regulated in formal competitions, in part resulting from the rise of gymnasiums and athletic clubs.
Freestyle wrestling is an international discipline and an Olympic sport, for both men and women. This style allows the use of the wrestler's or his opponent's legs in offence and defence.
There is a wide range of styles with varying rules with both traditional historic and modern styles. Wrestling techniques have been incorporated into other martial arts as well as military hand-to-hand combat systems.
