Boxing, nicknamed the "sweet science" and also called pugilism or prizefighting, is a sport where two participants of similar weight attack each other with their fists in a series of one to three-minute intervals called "rounds". In both amateur and professional divisions, the combatants (called boxers or fighters) avoid their opponent's punches whilst trying to land punches of their own. Points are awarded for clean, solid blows to the legal area on the front of the opponent's body above the waistline, with hits to the head and torso being especially valuable. The fighter with the most points after the scheduled number of rounds is declared the winner. Victory may also be achieved if the opponent is knocked down and unable to get up before the referee counts to ten (a Knockout, or KO) or if the opponent is deemed too injured to continue (a Technical Knockout, or TKO).

History:
Earliest evidence suggests that boxing was prevalent in North Africa during 4000 BC and the Mediterranean in 1500 BC.

A Greek ruler named Thesus, who ruled around 900 B.C., was entertained by men who would be seated in front of each other and beat another with their fists until one of them was killed. In time, the fighters fought on their feet and wore gloves (not padded) and wrappings on their arms below the elbows, but were otherwise naked when competing. First accepted as an Olympic sport (the ancient Greeks called it Pygme/ Pygmachia) in 688 BC, participants in the ancient games trained on punching bags (called a korykos). Keeping their fingers free, fighters then wore leather straps (called himantes) on their hands, wrists, and sometimes lower arms, to protect them from injury.

In Ancient Rome, fighters were usually criminals and slaves. They hoped to become champions and gain their freedom. However, free men also fought. Eventually, fist fighting became so popular that even aristocrats started fighting, but that was banned by the ruler Augustus. In 500 A.D., the sport was banned by Theodoric the Great.

Amateur Boxing:
In amateur boxing (the version of the sport found at the Olympic Games and Commonwealth Games) the primary emphasis is on landing scoring punches rather than concern with doing physical damage to one's opponent. Competitors wear protective headgear and box for three to five rounds of two or three minutes each. Gloves in amateur boxing have a white strip across the knuckle. A punch is considered a scoring punch only when the boxers connect with the white portion of the gloves. Each punch that lands on the head or torso is awarded a point. A referee monitors the fight to ensure that competitors use only legal blows (a belt worn over the torso represents the lower limit of punches - any boxer repeatedly landing "low blows" is disqualified). Referees also ensure that the boxers don't use holding tactics to prevent the opponent from swinging (if this occurs, the referee separates the opponents and orders them to continue boxing. Repeated holding can result in a boxer being penalized, or ultimately, disqualified).

Also, in amateur boxing, referees will readily step in and stop the contest even if the competitor is only relatively lightly injured. As a result, the risk of grievous injury is considerably reduced in amateur boxing versus professional boxing.

Professional Boxing:
Professional bouts are far longer than amateur bouts (ranging from four to twelve rounds), headgear is not permitted, and boxers are generally allowed to take much more punishment before a fight is halted. At any time, however, the referee may stop the contest if he believes that one participant can not or should not continue to box. In that case, the other participant is awarded a technical knockout win, which appears on the boxer's record as a knockout win (or loss). A technical knockout would also be awarded if a fighter lands a punch that opens a cut on the opponent, and the opponent is later deemed not fit to continue by a doctor because of the cut. If a boxer simply quits fighting, or if his corner stops the fight, then the winning boxer is also awarded a technical knockout victory.

If a knockout or disqualification does not occur, the fight must go to the scorecards. Professional fights have three judges each, and each of the judges must use the 10 point must system: Under this system, each time a boxer wins a round in the judges' eyes, the judge gives that boxer 10 points, and the other 9 or less. If the judge deems the round to be a tie, he or she may score it 10-10. When the fight reaches its scheduled distance, all scores are added, round by round, to determine who won on each judges' cards. When all three judges have the same boxer as the winner, this is an unanimous decision. When two judges have one boxer winning the fight and the other one has it a tie, this is called a majority decision. When two judges have one boxer winning the fight and the other judge has the other boxer winning, this is called a split decision. When one judge gives his or her vote to one boxer, another one gives it to the other boxer, and the third judge calls it a tie, this is a draw. It is also a draw when two judges score the fight a tie, regardless of who the third judge score the bout for.

In the United Kingdom, the bout is only scored by the referee, except when a title is at stake, in which case it is scored by three judges.

If a fight can not go on because of an injury caused to one of the competitors by a headbutt, there are different rules: If the fight has not reached the end of round three, (in some places, round four), the fight is declared a technical draw or a no contest. If it has reached beyond the end of round three (or four), then the scorecards are read and whoever is ahead, wins by a technical decision.
