If the Olympic Games are a history of mankind, wrestling is the prologue. When the ancient Games of the Olympiad were born, wrestling already was an ancient game.
Widely recognised as the world's oldest competitive sport, wrestling appeared in a series of Egyptian wall paintings as many as 5000 years ago. When the Games began in 776 BC, more than two millenniums later, it included wrestling, and, in the years that followed, wrestling featured as the main event.
