Mixed martial arts (MMA) is a full contact combat sport that allows the use of both striking and grappling techniques, both standing and on the ground, including boxing, wrestling, Brazilian jiu-jitsu, muay Thai, kickboxing, taekwondo, karate, judo and other styles. The roots of modern mixed martial arts can be traced back to the ancient Olympics where one of the earliest documented systems of codified full range unarmed combat was utilized in the sport of Pankration. Various mixed style contests took place throughout Europe, Japan and the Pacific Rim during the early 1900s. The combat sport of Vale Tudo that had developed in Brazil from the 1920s was brought to the United States by the Gracie family in 1993 with the founding of the Ultimate Fighting Championship (UFC), which is the largest MMA promotion company worldwide.

The more dangerous Vale Tudo style bouts of the early UFCs were made safer with the implementation of additional rules, leading to the popular regulated form of MMA seen today. Originally promoted as a competition with the intention of finding the most effective martial arts for real unarmed combat situations, competitors were pitted against one another with minimal rules. Later, fighters employed multiple martial arts into their style while promoters adopted additional rules aimed at increasing safety for competitors and to promote mainstream acceptance of the sport. The name mixed martial arts was coined by Rick Blume, president and CEO of Battlecade, in 1995. Following these changes, the sport has seen increased popularity with a pay per view business that rivals boxing and professional wrestling.

Martial arts are extensive systems of codified practices and traditions of combat that are practiced for a variety of reasons, including self-defense, competition, physical health and fitness, as well as mental, physical and spiritual development. The term martial art has become heavily associated with the fighting arts of eastern Asia, but was originally used in regard to the combat systems of Europe as early as the 1550s. An English fencing manual of 1639 used the term in reference specifically to the "Science and Art" of swordplay. The term is ultimately derived from Latin, martial arts being the "Arts of Mars," the Roman god of war. Some martial arts are considered 'traditional' and tied to an ethnic, cultural or religious background, while others are modern systems developed either by a founder or an association.

Martial arts may be categorized along a variety of criteria, including:

Unarmed martial arts can be broadly grouped into focusing on strikes, those focusing on grappling and those that cover both fields, often described as hybrid martial arts.

Marcus Valerius Martialis (known in English as Martial) (March 1, 40 AD – between 102 and 104 AD), was a Latin poet from Hispania (the Iberian Peninsula) best known for his twelve books of Epigrams, published in Rome between AD 86 and 103, during the reigns of the emperors Domitian, Nerva and Trajan. In these short, witty poems he cheerfully satirises city life and the scandalous activities of his acquaintances, and romanticises his provincial upbringing. He wrote a total of 1,561, of which 1,235 are in elegiac couplets. He is considered to be the creator of the modern epigram.

Knowledge of his origins and early life are derived almost entirely from his works, which can be more or less dated according to the well-known events to which they refer. In Book X of his Epigrams, composed between 95 and 98, he mentions celebrating his fifty-seventh birthday; hence he was born on March 1 (x. 24) 38, 39, 40 or 41 AD, under Caligula or Claudius. His place of birth was Augusta Bilbilis (now Calatayud) in Hispania Tarraconensis. His parents, Fronto and Flaccilla, appear to have died in his youth.

Bruce Lee (born Lee Jun-fan; 27 November 1940 – 20 July 1973) was a Chinese AmericanHong Kong actor,martial arts instructor, philosopher, film director, film producer, screenwriter, and founder of the Jeet Kune Do martial arts movement. He is widely considered by many commentators, critics, media and other martial artists to be the most influential martial artist and pop culture icon of the 20th Century. He is often credited with changing the way Asians were presented in American films.

Lee was born in San Francisco to parents of Hong Kong heritage but was raised in Hong Kong until his late teens. Lee returned to the United States at the age of 18 to claim his U.S. citizenship and receive his higher education. It was during this time that he began teaching martial arts, which soon led to film and television roles.

His Hong Kong and Hollywood-produced films elevated the traditional Hong Kong martial arts film to a new level of popularity and acclaim, and sparked a major surge of interest in Chinese martial arts in the West in the 1970s. The direction and tone of his films changed and influenced martial arts and martial arts films in Hong Kong and the rest of the world, as well. He is noted for his roles in five feature-length films: Lo Wei's The Big Boss (1971) and Fist of Fury (1972); Way of the Dragon (1972), directed and written by Lee; Warner Brothers' Enter the Dragon (1973) and The Game of Death (1978), both directed by Robert Clouse.
