Wrestling is a form of combat sport involving grappling type techniques such as clinch fighting, throws and takedowns, joint locks, pinsand other grappling holds. A wrestling bout is a physical competition, between two (occasionally more) competitors or sparring partners, who attempt to gain and maintain a superior position. There are a wide range of styles with varying rules with both traditional historic and modern styles. Wrestling techniques have been incorporated into other martial arts as well as military hand-to-hand combat systems.

The term wrestling is attested in late Old English, as wræstlunge (glossing palestram).^[2]Wrestling represents one of the oldest forms of combat. Literary references to it occur as early as in the Iliad, in which Homer recounts the Trojan War of the 13th or 12th century BC.^[3] The origins of wrestling go back 15,000 years through cave drawings in France. Babylonian and Egyptian reliefs show wrestlers using most of the holds known in the present-day sport.

In ancient Greece wrestling occupied a prominent place in legend and literature; wrestling competition, brutal in many aspects, served as the focal sport of the ancient Olympic Games. The ancient Romans borrowed heavily from Greek wrestling, but eliminated much of its brutality.

During the Middle Ages (fifth century to fifteenth century) wrestling remained popular and enjoyed the patronage of many royal families, including those of France, Japan and England.

Early European settlers in America brought a strong wrestling tradition with them if they came from England. The settlers also found wrestling to be popular among Native Americans.^{[citation needed]} Amateur wrestling flourished throughout the early years of the North American colonies and served as a popular activity at country fairs, holiday celebrations, and in military exercises. The first organized national wrestling tournament took place in New York City in 1888, while the first wrestling competition in the modernOlympic Games occurred in 1904 in Saint Louis, Missouri.^{[citation needed]} - apart from the Olympic wrestling at Athens in 1896. The International Federation of Associated Wrestling Styles (FILA) originated in 1912 in Antwerp, Belgium. The 1st NCAA Wrestling Championships were also held in 1912, in Ames, Iowa. USA Wrestling, located in Colorado Springs, Colorado, became the national governing body of amateur wrestling in 1983. It conducts competitions for all age-levels.Greco-Roman wrestling and modern freestyle wrestling were soon regulated in formal competitions, in part resulting from the rise of gymnasiums and athletic clubs.

On continental Europe, prize money was offered in large sums to the winners of Greco-Roman tournaments, and freestyle wrestling spread rapidly in the United Kingdom and in the United States after the American Civil War. Wrestling professionals soon increased the popularity of Greco-Roman and freestyle wrestling, worldwide.^[6][9]

• Greco-Roman wrestling became an event at the first modern Olympic games, in Athens in 1896. Since 1908, the event has been in every Summer Olympics.

• Freestyle wrestling became an Olympic event, in 1904. Women's freestyle wrestling was added to the Summer Olympics in 2004.

Since 1921, the International Federation of Associated Wrestling Styles (FILA) has regulated amateur wrestling as an athletic discipline, while professional wrestling has largely become infused with theatrics but still requires athletic ability. Today, various countries send national wrestling teams to the Olympics, including Russia, Iran, Turkey, Mongolia, Azerbaijan, Gambia, the United States and several ex-U.S.S.R nations.Wrestling disciplines defined by FILA, are broken down into two categories; International wrestling disciplines and folk wrestling disciplines. According to the International Federation of Associated Wrestling Styles, there are five current International wrestling disciplines acknowledged throughout the world. They are Greco-Roman Wrestling, Freestyle Wrestling, Grappling, Beach wrestling and MMA.^[10]Greco-Roman is an international discipline and an Olympic sport. In Greco-Roman style, it is forbidden to hold the opponent below the belt, to make trips, and to actively use the legs in the execution of any action. Recent rule changes in Greco-Roman increase opportunities for and place greater emphasis on explosive, 'high amplitude' throws. Pinning one's opponent to the mat is one way of winning. One of the most well known Greco-Roman wrestlers is Alexander Karelin from Russia.Freestyle wrestling is an international discipline and an Olympic sport, for both men and women. This style allows the use of the wrestler's or his opponent's legs in offense and defense. Freestyle wrestling has its origins in catch-as-catch-can wrestling and the prime victory condition in this style involves the wrestler winning by throwing and pinning his opponent on the mat. American high school and college wrestling is conducted under different rules and is termed scholastic and collegiate wrestling. Outside the U.S., one can find professional wrestlers who compete by the rules of freestyle wrestling.FILA Grappling is a wrestling style that consists of controlling the opponent without using striking and also includes the use ofsubmission holds. It is also referred to as “submission grappling.” It starts from a standing position or on the ground after a throw, and the goal is to make the opponent submit via the use of immobilization techniques such as locks. Grappling, differing from the FILA definition, plays an important role in the practice of Mixed Martial Arts (MMA) and can be used as a self-defence technique. It brings together techniques from Brazilian jiu-jitsu, Freestyle Wrestling, American Folk Wrestling (catch-as-catch-can), sambo, and judo. Grapplers wear shorts and a tight shirt (No-Gi) or kimonos (Gi).^[11]Combat grappling is a form of safe amateur Mixed Martial Arts (MMA) that incorporates techniques from most existing Martial Arts systems, creating a unique fighting environment that alternatively takes the fight from standing to ground positions. Combat grappling matches are either won by grappling holds such as joint locks and chokes, or by striking and kicking techniques. Combat grappling also intends to be a realistic form of self-defense covering all aspects of standing and ground fighting, thus making it perfect and safe to use for military, police, and security training.^[12]FILA codified the current form of Beach Wrestling in 2004.^[13] Beach wrestling is standing wrestling done by wrestlers, male or female, inside a sand-filled circle measuring 6 meters (20 ft) in diameter with only two weight categories, heavy and light. The wrestlers wear swimsuits rather than special wrestling uniforms. Wrestlers may also wear spandexor athletic shorts. The objective is to bring the opponent to the ground, push them out of bounds or pin their shoulders to the ground.^[14][15]Folk wrestling describes a traditional form of wrestling unique to a culture or geographic region of the world that FILA does not administer rules for. Examples of the many styles of folk wrestling, include backhold wrestling (from Europe), Cumberland wrestlingand Catch-as-catch-can (from England), kurash from Uzbekistan, gushteengiri from Tajikistan, khuresh from Siberia, Lotta Campidanese from Italy, koshti pahlavani from Iran, naban from Myanmar, pehlwani from India, penjang gulat from Indonesia,schwingen from Switzerland, tigel from Ethiopia, shuai jiao from China, and ssireum from Korea.

Folk wrestling styles are not recognized as international styles of wrestling by FILA.First2Ten is a form of wrestling unique to the United States. The form was developed by the Association of Career Wrestlers and is used in their Tour ACW series. The rules for scoring are largely influenced by Olympic Freestyle and the United States Folk style rules used in Collegiate Wrestling.

First2Ten is not recognized as an international style of wrestling, by FILA.Oil wrestling (Turkish: yağlı güreş), also called grease wrestling, is the Turkish national sport. It is so called because the wrestlers douse themselves with olive oil. It is related to Uzbek kurash, Tuvan khuresh and Tatar köräş. The wrestlers, known as pehalvan meaning "champion" wear a type of hand-stitched lederhosen called a kispet, which are traditionally made of water buffalo hide, and most recently have been made of calfskin.

Unlike Olympic wrestling, oil wrestling matches may be won by achieving an effective hold of the kisbet. Thus, the pehalvan aims to control his opponent by putting his arm through the latter's kisbet. To win by this move is called paça kazık. Originally, matches had no set duration and could go on for one or two days, until one man was able to establish superiority, but in 1975 the duration was capped at 40 minutes for the baspehlivan and 30 minutes for the pehlivan category. If no winner is determined, another 15 minutes—10 minutes for the pehlivan category—of wrestling ensues, wherein scores are kept to determine the victor.

The annual Kırkpınar tournament, held in Edirne in Turkish Thrace since 1362, is the oldest continuously running, sanctioned sporting competition in the world. In recent years this style of wrestling has also become popular in other countries.Collegiate wrestling (sometimes known as scholastic wrestling or folkstyle wrestling) is the commonly used name of wrestling practiced at the college and university level in the United States. This style, with modifications, is also practiced at the high schooland middle school levels, and also for younger participants. The term is used to distinguish the style from other styles of wrestling used in other parts of the world, and from those of the Olympic Games: Greco-Roman wrestling, and Freestyle wrestling. Some high schools in the U.S. have developed junior varsity and freshman teams alongside varsity teams. Junior varsity and freshman wrestling teams restrict competitors not only by weight, but also by age and the amount of wrestling a competitor can partake in. For example, some junior varsity and freshman competitors are not allowed in tournament competition due to the amount of mat time a wrestler would accrue in a short time period.

There are currently several organizations which oversee collegiate wrestling competition: Divisions I, II, and III of the NCAA, theNJCAA, the NAIA, and the NCWA. NCAA Division I wrestling is considered the most prestigious and challenging level of competition. A school chooses which athletic organization to join, although it may compete against teams from other levels and organizations during regular-season competition. The collegiate season starts in October or November and culminates with theNCAA tournament held in March.^[16]Sambo is a martial art that originated in the Soviet Union (specifically Russia) in the 20th century. It is an acronym for "self-defence without weapons" in Russian and had its origins in the Soviet armed forces. Its influences are varied, with techniques borrowed from sports ranging from the two international wrestling styles of Greco-Roman and freestyle to judo, jiu-jitsu, European styles of folk wrestling, and even fencing. The rules for sport sambo are similar to those in competitive judo, with a variety of leglocks and defense holds from the various national wrestling styles in the Soviet Union, while not allowing chokeholds.^[17]Pankration, from the Greek words "Pan" and "Kratos" meaning "the one who controls everything", is a world heritage martial art with the unique distinction of being the only martial sport in existence today that can legitimately trace its roots to the ancient Olympic Games from 648 BC to 393 AD. Today, pankration is developed by FILA as a mild form of Mixed Martial Arts (MMA).^[18]Professional competitive wrestling is uncommon.^{[citation needed]} Professional wrestling refers in practice to "sports entertainment", where staged combat is 'worked' to an arranged outcome.Professional wrestling is organised by bodies such as WWE. The athletes mostly use the traditional Anglo-American catch wrestling holds. Fights are highly theatrical, with dramatic stories such as feuds between fighters developed and performed as part of build-up and promotion for matches.Japanese professional wrestling, also known as puroresu, is treated as a sport rather than the entertainment style of wrestling found in North America. There are no storylines or any sort of angle found in most puroresu promotions. The matches have the atmosphere of real wrestling competition. Techniques include use of amateur or shoot wrestling tactics in addition to hard hitting martial arts strikes and complex submission maneuvers. This means that the wrestlers are more prone to injury. Popular Japanese wrestlers includeKenta Kobashi, Tiger Mask, The Great Muta, Jun Akiyama, Jushin "Thunder" Liger, and KENTA.Mexican professional wrestling, also known as Lucha libre is a style of wrestling that combines mixed-martial arts and the wrestling of North America. In Lucha libre the wrestler orluchador uses a mask to cover his face. Traditionally the match is for the best of three rounds without a time limit. The "Luchador" or "wrestler" athlete uses their own wrestling style or "estilo de lucha" consisting of aerial attack wrestling moves, strikes and complex submission moves. The most popular luchadores are Santo, Blue Demon, Rey Mysterio, Eddie Guerrero, La Parka, Dos Caras Jr./Alberto Del Rio and Mistico.In Germany, "Berufsringen" refers to wrestling where professional wrestlers fight by traditional rules, and "Wrestling" refers to the professional wrestling of U.S. promotions. The German language makes this distinction clear, as the term 'Ringen' is used to designate sport wrestling in any of the Olympic or folk styles, while the terms 'Wrestling' and 'Catchen' refers to professional wrestling entertainment; a sport wrestler is a 'Ringer' and a professional wrestling star is a 'Wrestler' or 'Catcher'. Ringer-Bundesliga is the top level of professional team wrestling.Grappling and striking skills are both of importance in mixed martial arts competitions. Fighters who were accomplished wrestlers, gained respect during the early stages of MMA development.^[19] Some of these, went on to win several early Ultimate Fighting Championships (UFC 5, 6, 8, 9, 10, 12).^[19]

Successful fighters in modern MMA who began their training in various forms of wrestling, include Jon Jones, Frank Edgar, Cain Velasquez, former Olympic wrestler Daniel Cormier and Brock Lesnar, a former UFC heavyweight champion who was a NCAA wrestling champion in 2000 and achieved 2nd place 1999,^[20] and former champions Dan Henderson, of PRIDE FC and Randy Couture, a multi-time UFC champion, both of whom competed extensively in collegiate and Greco-Roman wrestling before beginning their careers in mixed martial arts.
