Bokator[a] is an ancient battlefield martial art used by ancient Khmer military groups. It is one of the oldest existing fighting systems originating from Cambodia.
Oral tradition indicates that bokator (or an early form thereof) was the close quarter combat system used by the ancient Cambodian armies before the founding of Angkor. A common misconception is that bokator refers to all Khmer/Cambodian martial arts, while in reality it only represents one particular style.
Bokator is characterized by hand to hand combat along with heavy use of weapons. Bokator uses a diverse array of elbow and knee strikes, shin kicks, submissions and ground fighting. Some of the weapons used in bokator include the bamboo staff, short sticks, sword and lotus stick(20 cm long wooden weapon).  
When fighting, bokator exponents still wear the uniforms of ancient Khmer armies. A krama (scarf) is folded around their waist and blue and red silk cords called, sangvar day are tied around the combatants head and biceps. In the past the cords were believed to be enchanted to increase strength, although now they are just ceremonial.
The art contains 341 sets which, like many other Asian martial arts, are based on the study of life in nature. For example, there are styles of elephant, duck, crab, horse, bird and crocodile with each containing several techniques. Unlike its neighbors, Cambodia has a history of being a Hindu nation. In addition to animal styles, bokator has techniques based on Hindu deities such as hanuman and apsara.
For his school of bokator, San Kim Sean developed a krama based system similar to a belt system to organize and represent the training levels. The krama shows the fighter’s level of expertise. The first grade is white, followed by green, blue, red, brown, and finally black, which has 10 degrees. After completing their initial training, fighters wear a black krama for at least another ten years. To attain the gold krama one must be a true master and must have done something great for bokator. This is most certainly a time-consuming and possibly lifelong endeavor: in the unarmed portion of the art alone there are between 8000 and 10000 different techniques, only 1000 of which must be learned to attain the black krama.
Bokator is considered to be the oldest martial art currently being practiced in the Kingdom of Cambodia.  Although there are no records to prove this, the term bokator is itself a possible indicator of its age. Bokator appears in the first Khmer dictionary developed in 1938 by the Buddhist scholar Chuon Nath.  Pronounced "bok-ah-tau", the word comes from labokatao meaning "to pound a lion". This refers to a story alleged to have happened 2,000 years ago. According to the legend, a lion was attacking a village when a warrior, armed with only a knife, defeated the animal bare-handed, killing it with a single knee strike. Though the lion is of cultural importance to Indochina, it is treated by modern and recent literature as being outside even the historical range of the Asiatic lion, which currently survives in western India. Instead, big cats of Southeast Asia include the Indochinese leopard and tiger. Indian culture and philosophy were the major influences in Angkor culture. All the great buildings of Angkor are inscribed in Sanskrit and are devoted to Hindu gods, notably Vishnu and Shiva. Even today, bokator practitioners begin each training session by paying respect to Brahma. Religious life was dominated by Brahmins who in India also practiced sword fighting and empty-hand techniques. The concept of the lion and bokator's animal-based techniques most likely emerged during the reign of the Angkor kings and the concurrent influence of Indian martial arts.
Cambodia has the largest surviving depictions of ancient martial arts in the world. Angkor Wat, the world's largest temple, has gigantic bas-relief murals that depict martial arts and battles dating back to the temple's creation 900 years ago. The man responsible for the construction of Angkor Wat was the warlike King Suryavarman II.  By 1113, Suryavarman II defeated his rivals and established himself as the only ruler of the Khmer Empire. At his temple of Angkor Wat, Suryavarman II is seen reviewing the soldiers of his empire. Other ancient temples such as the Bayon and Banteay Chhmar also depict martial arts bas-reliefs. The Bayon is a temple that was constructed at the order of King Jayavarman VII. The bas-reliefs at the Bayon show the military victories of Jayavarman VII.  Bas-reliefs at the base of the entrance pillars to the Bayon, Jayavarman VII's state temple, depict various techniques of bokator. One relief shows two men appearing to grapple, another shows two fighters using their elbows. Both are standard techniques in modern kun Khmer, or pradal serey. A third depicts a man facing off against a rising cobra and a fourth shows a man fighting a large animal. Cambodia's long martial heritage may have been a factor in enabling a succession of Angkor kings to dominate Southeast Asia for more than 600 years beginning in AD 800.
The former capital, Longvek, use to serve as center of the country's military. It was a gathering point for people of knowledge including scholars and martial artists. According to bokator master Om Yom, areas such as Svay Chrum District, Kraing Leav and Pungro in Rolea B'ier District of Kampong Chhnang Province used to be areas known for training in martial arts. The national military still continues to train in that area today.
As stated by bokator master Som On, bokator fighters did not publicly train in the open like they do in modern times but instead trained in secret.
At the time of the Pol Pot regime (1975–1979) those who practiced traditional arts were either systematically exterminated by the Khmer Rouge, fled as refugees or stopped teaching and hid. After the Khmer Rouge regime, the Vietnamese occupation of Cambodia began and native martial arts were completely outlawed. San Kim Sean (or Sean Kim San according to the English name order) is often referred to as the father of modern bokator and is largely credited with reviving the art. During the Pol Pot era, San Kim Sean had to flee Cambodia under accusations by the Vietnamese of teaching hapkido and bokator (which he was) and starting to form an army, an accusation of which he was innocent. Once in America he started teaching hapkido at a local YMCA in Houston, Texas and later moved to Long Beach, California. After living in the United States and teaching and promoting hapkido for a while, he found that no one had ever heard of bokator. He left the United States in 1992 and returned home to Cambodia to give bokator back to his people and to do his best to make it known to the world.
In 2001, San Kim Sean moved back to Phnom Penh and after getting permission from the new king began teaching bokator to local youth. That same year in the hopes of bringing all of the remaining living masters together he began traveling the country seeking out bokator lok kru, or instructors, who had survived the regime. The few men he found were old, ranging from sixty to ninety years of age and weary of 30 years of oppression; many were afraid to teach the art openly. After much persuasion and with government approval, the former masters relented and Sean effectively reintroduced bokator to the Cambodian people. Contrary to popular belief, San Kim Sean is not the only surviving labokatao master. Others include Meas Sok, Meas Sarann, Ros Serey, Sorm Van Kin, Mao Khann and Savoeun Chet. There were other martial artists that were trained in bokator but didn't feel comfortable teaching because they were not at a master level. The first ever national Bokator competition was held in Phnom Penh at the Olympic Stadium, from September 26–29, 2006. The competition involved 20 lok krus leading teams from nine provinces.
In 2017, Bokator was highlighted in the successful Cambodian martial arts film Jailbreak., A production team did research on bokator for the Southeast Asian theme Disney movie, Raya and the Last Dragon.
