Boxing
Boxing (sometimes known as pugilism, Anglais boxing, or English boxing) is a combat sport in which two participants (generally) of similar weight fight each other with their fists. Boxing today is conducted in a regulated way, typically in a series of one to three-minute intervals called rounds. Victory is 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). If there is no stoppage of the fight before an agreed number of rounds, a winner is determined either by the referee's decision or by judges' scorecards.
While people have fought with fists probably since immemorial times, the ancient Greeks were the first to make a sport of it, by giving rules and staging tournaments with professionals. The birth hour of boxing as a sport may mark its allowance as an Olympic game as early as 688 BC. Modern boxing evolved in Europe, particularly Great Britain.
