Mixed martial arts (MMA) is a
full contact combat sport that allows a wide variety of fighting techniques, from a mixture of martial arts traditions and non-traditions, to be used in competitions. The rules allow the use of striking and grappling techniques, both while standing and on the ground. Such competitions allow martial artists of different backgrounds to compete.Modern mixed martial arts competition emerged in American popular culture in 1993 with the founding of the
Ultimate Fighting Championship. Originally organized with the intention of finding the most effective martial arts for real unarmed combat situations, competitors of various arts were pitted against one another with minimal rules for safety. In the following decade, MMA promoters adopted many additional rules aimed at increasing safety for competitors and to promote mainstream acceptance of the sport. The name mixed martial arts was coined by one of the developers of these rules, Jeff Blatnick, a former Greco-Roman wrestler and Olympic gold medalist.
History
Pre-modern
Pankration was an ancient form of unarmed hand to hand combat resembling modern MMA.
While different forms of unorganized, no-rules, unarmed combat predate history, civilization, and even the human species itself (even apes fight hand-to-hand), the earliest documented, organized, minimal-rules fighting event was the ancient Greek pankration, which was introduced into the Olympic Games in 648 B.C. Greek pankration later inspired the more violent Etruscan and Roman pancratium, an event showcased at the Roman Colosseum. Even as late as the Early Middle Ages, statues were put up in Rome and other cities to honour remarkable pankratiasts of Rome.
No-holds-barred events reportedly took place in the late 1800s when wrestlers representing a huge range of fighting styles, including various catch wrestling styles, Greco-Roman wrestling and many others met in tournaments and music-hall challenge matches throughout Europe. In the USA the first major encounter between a boxer and a wrestler in modern times took place in 1887 when John L. Sullivan, then heavyweight world boxing champion, entered the ring with his trainer, Greco-Roman wrestling champion William Muldoon, and was slammed to the mat in two minutes. The next publicized encounter occurred in the late 1890s when future heavyweight boxing champion Bob Fitzsimmons took on European Greco-Roman wrestling champion Ernest Roeber. Reportedly, Roeber suffered a fractured cheekbone in this bout, but was able to get Fitzsimmons down on the mat, where he applied an armlock and made the boxer submit.
In Europe, around the 19th century, the Italian Giovanni Raicevich, skilled in Greco-Roman wrestling defeated Akitaro Ono, a Japanese heavyweight fighter skilled in Jujutsu, Judo, and Sumo, throwing him on the mat by one-arm shoulder throw. In 1936, heavyweight boxing contender Kingfish Levinsky and veteran professional wrestler Ray Steele competed in a mixed match, which Steele won in 35 seconds.
Another early example of mixed martial arts combat was the martial art of Bartitsu, founded in London in 1899, which was the first martial art known to have combined Asian and European fighting styles, and which saw MMA-style contests throughout England, pitting European and Japanese champions against representatives of various European wrestling styles. Mixed style contests such as boxing vs. jujutsu were popular entertainment throughout Europe, Japan and the Pacific Rim during the early 1900s.[8] In Japan these contests were known as merikan, from the Japanese slang for "American [fighting]". Merikan contests were fought under a variety of rules including points decision, best of three throws or knockdowns, and victory via knockout or submission.
Professional wrestling died out after World War I and was reborn in two streams: "shoot", in which the fighters actually competed, and "show," which evolved into modern professional wrestling. In the late 1960s to early 1970s the concept of combining the elements of multiple martial arts had was popularized in America by Bruce Lee via his system and philosophy of Jeet Kune Do. Lee believed that "the best fighter is not a Boxer, Karate or Judo man. The best fighter is someone who can adapt to any style."[attribution needed] In 2004 UFC President Dana White would call Lee the "father of mixed martial arts."

Modern
The history of modern MMA competition can be traced to mixed style contests throughout Europe, Japan and the Pacific Rim during the early 1900s; the Gracie family's vale tudo martial arts tournaments in Brazil starting in the 1920s; and early mixed martial arts matches (known as Kakutougi in Japan) hosted by Antonio Inoki in Japan in the 1970s. The sport gained international exposure and widespread publicity in the United States in 1993, when Brazilian Jiu-Jitsu fighter Royce Gracie handily won the first Ultimate Fighting Championship tournament, subduing three challengers in just five minutes, sparking a revolution in the martial arts. Meanwhile in Japan the continued interest in the sport resulted in the creation of the Pride Fighting Championships in 1997.
The movement that led to the creation of the UFC, and Pride was rooted in two interconnected subcultures. First were the vale tudo events in Brazil, followed by the Japanese shoot wrestling shows. Vale tudo began in the 1920s with the "Gracie challenge" issued by Carlos Gracie and Hélio Gracie and upheld later on by descendants of the Gracie family. In Japan in the 1970s, a series of mixed martial arts matches were hosted by Antonio Inoki, a former star of New Japan Pro Wrestling; this inspired the shoot-style movement in Japanese professional wrestling, which eventually led to the formation of the first mixed martial arts organizations, such as Shooto, which was formed in 1985.
In November 2005 recognition of its effectiveness as a test came as the United States Army began to sanction mixed martial arts with the first annual Army Combatives Championships held by the US Army Combatives School. The sport reached a new peak of popularity in North America in the December 2006 rematch between then UFC light heavyweight champion Chuck Liddell and former champion Tito Ortiz, rivaling the PPV sales of some of the biggest boxing events of all time,[4] and helping the UFC's 2006 PPV gross surpass that of any promotion in PPV history. In 2007, Zuffa LLC, the owners of the UFC MMA promotion, bought Japanese rival MMA brand Pride FC, merging the contracted fighters under one promotion[15] and drawing comparisons to the consolidation that occurred in other sports, such as the AFL-NFL Merger in American football.
Rules
Technical Knockout (TKO)
Referee stoppage: The ref may stop a match in progress if:
- a fighter becomes dominant to the point where the opponent can not intelligently defend himself and is taking a lot of damage
- a fighter appears to be unconscious from a submission hold or due to a strike
- a fighter appears to have a significant injury such as a cut or a broken bone
Doctor Stoppage: the referee will call for a time out if a fighter's ability to continue is in question as a result of apparent injuries, such as a large cut. The ring doctor will inspect the fighter and stop the match if the fighter is deemed unable to continue safely, rendering the opponent the winner. However, if the match is stopped as a result of an injury from illegal actions by the opponent, either a disqualification or no contest will be issued instead.
Corner stoppage: a fighter's corner men may announce defeat on the fighter's behalf by throwing in the towel during the match in progress or between rounds.
Decision: if the match goes the distance, then the outcome of the bout is determined by three judges. The judging criteria are organization-specific. Forfeit: a fighter or his representative may forfeit a match prior to the beginning of the match, thereby losing the match.
Disqualification: a "warning" will be given when a fighter commits a foul or illegal action or does not follow the referee's instruction. Three warnings will result in a disqualification. Moreover, if a fighter is injured and unable to continue due to a deliberate illegal technique from his opponent, the opponent will be disqualified.
No Contest: in the event that both fighters commit a violation of the rules, or a fighter is unable to continue due to an injury from an accidental illegal technique, the match will be declared a "No Contest".
