Boxing is a combat sport and martial art in which two populace fight using their fists. Boxing is typically supervised by a referee engaged in during a series of one- to three-minute intervals called rounds, and boxers generally of similar weight.

There are three ways to win; if the opponent is knocked out and unable to get up previous to the referee counts to ten seconds (a Knockout, or KO) or if the opponent is deemed too injured to continue (a Technical Knockout, or TKO). If there is no stoppage of the fight before an arranged number of rounds, a winner is strong-minded either by the referee's decision or by judges' scorecards. Fist fighting depicted in Sumerian relief carvings from the 3rd millennium BC.

While an ancient Egyptian relief from the 2nd millennium BC depicts both fist-fighters and spectators. Both depictions show bare-fisted contests.

In 1927 Dr. E. A. Spenser, an archaeologist, discovered a Mesopotamian stone tablet in Baghdad, Iraq depicting two men getting ready for a prize fight. The tablet is believed to be 7,000 years old. The initial evidence for fist fighting with any kind of gloves can be found on Minoan Crete (c. 1500?900 BC), and on Sardinia, if we consider the boxing statues of Parma mountains (c. 2000?1000 BC).In ancient Rome, there were two forms of boxing both coming from Etruscan boxing.

The athletic form of boxing remained well-liked right through the Roman world. The other form of boxing was gladiatorial. Fighters were usually criminals and slaves who hoped to become champions and gain their freedom; however, free men, women, and even aristocrats also fought. Gladiators wore lead "caste" over their knuckles and heavy fleece straps on their forearms to protect against blows. The deeply scarred and cauliflower eared figure of the Boxer of Quirinal show what a brutal sport it could be (matches often finish in the death or maiming of an opponent).
