Khmer people (Khmer: ខ្មែរ, Khmer pronunciation: [kʰmaːe], Northern Khmer pronunciation: [kʰmɛr]) are a Southeast Asian ethnic group native to Cambodia, accounting for 97.6% of the country's 15.9 million people.[11] They speak the Khmer language, which is part of the larger Austroasiatic language family found in parts of central, eastern and north eastern India and parts of Bangladesh in South Asia, and in other parts of Southeast Asia (including Vietnam), South China and numerous islands in the Indian Ocean.

The majority of the Khmer are followers of the Khmer style of Buddhism, a highly syncretic version that blends elements of Theravada Buddhism, Hinduism, animism and veneration of the dead.[12] Significant populations of Khmers reside in adjacent areas of Thailand (Northern Khmer) and the Mekong Delta region of neighboring Vietnam (Khmer Krom), while there are over one million Khmers in the Cambodian diaspora living mainly in France, the United States and Australia.



The majority of the world's Khmer people live in Cambodia, the population of which is over 90% Khmer.[13][14]

Thailand and Vietnam

There are also significant Khmer populations native to Thailand and Vietnam. In Thailand, there are over one million Khmer, mainly in Surin (Soren), Buriram (Borei Rom) and Sisaket (Sri Saket) provinces. Estimates for the number of Khmer in Vietnam (known as Khmer Krom) vary from the 1.1 million given by government data to seven million advocated by the Khmer Krom Federation.[15]

Western nations

Due to migration as a result of the Cambodian Civil War, there is a large Khmer diaspora residing in the United States, United Kingdom, Canada, Australia and France.


According to one Khmer legend attributed by George Coedes to a tenth century inscription, the Khmer race arose from the union of the brahmin Kambu Swayambhuva and the apsara ("celestial nymph") Mera. Their marriage is said to have given rise to the name Khmer and founded the Varman dynasty of ancient Cambodia.[25]

A more popular legend, reenacted to this day in the traditional Khmer wedding ceremony and taught in elementary school, holds that Cambodia was created when an Indian Brahmin priest named Kaundinya (commonly referred to as Preah Thoang) married Princess Soma, a Naga (Khmer: neak) princess. Kaundinya sailed to Southeast Asia following an arrow he saw in a dream. Upon arrival he found an island called kok thlok and, after conquering Soma's Naga army, he fell in love with her. As a dowry, the father of princess Soma drank the waters around the island, which was revealed to be the top of a mountain, and the land below that was uncovered became Cambodia. Kaundinya and Soma and their descendents became known as the Khmer and are said to have been the rulers of Funan, Chenla and the Khmer Empire.[26] This myth further explains why the oldest Khmer wats, or temples, were always built on mountaintops, and why today mountains themselves are still revered as holy places.

Arrival in Southeast Asia

The Khmers are one of the oldest ethnic groups in the area, having filtered into Southeast Asia around the same time as the Mon, who settled further to the west and to whom the Khmer are ancestrally related. Most archaeologists and linguists, and other specialists like Sinologists and crop experts, believe that they arrived no later than 2000 BCE (over four thousand years ago) bringing with them the practice of agriculture and in particular the cultivation of rice. This region is also one of the first places in the world to use bronze. They were the builders of the later Khmer Empire, which dominated Southeast Asia for six centuries beginning in 802, and now form the mainstream of political, cultural, and economic Cambodia.

The Khmers developed the Khmer alphabet, the earliest alphabet still in use in Southeast Asia, which in turn gave birth to the later Thai and Lao alphabets. The Khmers are considered by archaeologists and ethnologists to be indigenous to the contiguous regions of Isan, southern Laos, Cambodia and South Vietnam. That is to say the Khmer have historically been a lowland people who lived close to one of the tributaries of the Mekong River. The reason they migrated into Southeast Asia is not well understood, but scholars believe that Austroasiatic speakers were pushed south by invading Tibeto-Burman speakers from the north as evident by Austroasiatic vocabulary in Chinese, because of agricultural purposes as evident by their migration routes along major rivers, or a combination of these and other factors.

Like the other early peoples of Southeast Asia such as the Pyu, Mon, Chams, Malays and Javanese, the Khmer were part of Greater India, adopting Indian religions, sciences, and customs and borrowing from their languages. The first powerful trading kingdom in Southeast Asia, the Kingdom of Funan, was established in southeastern Cambodia and the Mekong Delta in the first century, although extensive archaeological work in Angkor Borei District near the modern Vietnamese border has unearthed brickworks, canals, cemeteries and graves dating to the fifth century BCE.

The Kingdom of Funan is considered to be the mother of all later Southeast Asian kingdoms. During the Funan period (1st century - sixth century CE) the Khmer also acquired Buddhism, the concept of the Shaiva imperial cult of the devaraja and the great temple as a symbolic world mountain. The rival Khmer Chenla Kingdom emerged in the fifth century and later conquered the Kingdom of Funan. Chenla was an upland state whose economy was reliant on agriculture whereas Funan was a lowland state with an economy dependent on maritime trade.

These two states, even after conquest by Chenla in the sixth century, were constantly at war with each other and smaller principalities. During the Chenla period (5th-8th century), Cambodians left the world's earliest known zero in one of their temple inscriptions. Only when King Jayavarman II declared an independent and united Cambodia in 802 was there relative peace between the two lands, upper and lowland Cambodia.

Jayavarman II (802–830), revived Cambodian power and built the foundation for the Angkorean empire, founding three capitals—Indrapura, Hariharalaya, and Mahendraparvata—the archeological remains of which reveal much about his times. After winning a long civil war, Suryavarman I (reigned 1002–1050) turned his forces eastward and subjugated the Mon kingdom of Dvaravati. Consequently, he ruled over the greater part of present-day Thailand and Laos, as well as the northern half of the Malay Peninsula. This period, during which Angkor Wat was constructed, is considered the apex of Khmer civilization.

Khmer Empire (802–1431)

The Khmer kingdom became the Khmer Empire and the great temples of Angkor, considered an archeological treasure replete with detailed stone bas-reliefs showing many aspects of the culture, including some musical instruments, remain as monuments to the culture of the Khmer. After the death of Suryavarman II (1113–50), Cambodia lapsed into chaos until Jayavarman VII (1181–1218) ordered the construction of a new city. He was a Buddhist, and for a time, Buddhism became the dominant religion in Cambodia. As a state religion, however, it was adapted to suit the Deva Raja cult, with a Buddha Raja being substituted for the former Shiva Raja or Vishnu Raja.

The rise of the Tai kingdoms of Sukhothai (1238) and Ayutthaya (1350) resulted in almost ceaseless wars with the Cambodians and led to the destruction of Angkor in 1431. They are said to have carried off 90,000 prisoners, many of whom were likely dancers and musicians.[27] The period following 1432, with the Cambodian people bereft of their treasures, documents, and human culture bearers, was one of precipitous decline.

Post Empire (1431-present)

In 1434, King Ponhea Yat made Phnom Penh his capital, and Angkor was abandoned to the jungle. Due to continued Siamese and Vietnamese aggression, Cambodia appealed to France for protection in 1863 and became a French protectorate in 1864. During the 1880s, along with southern Vietnam and Laos, Cambodia was drawn into the French-controlled Indochinese Union. For nearly a century, the French exploited Cambodia commercially, and demanded power over politics, economics, and social life.

During the second half of the twentieth century, the political situation in Cambodia became chaotic. King Norodom Sihanouk (later, Prince, then again King), proclaimed Cambodia's independence in 1949 (granted in full in 1953) and ruled the country until March 18, 1970, when he was overthrown by General Lon Nol, who established the Khmer Republic. On April 17, 1975, the genocidal Khmer Rouge led by Saloth Sar, better known by his alias, Pol Pot, came to power and virtually destroyed the Cambodian people, their health, morality, education, physical environment, and culture.

On January 7, 1979, Vietnamese forces ousted the Khmer Rouge. After more than ten years of painfully slow rebuilding, with only meager outside help, the United Nations intervened resulting in the Paris Peace Accord on October 23, 1992 and created conditions for general elections in May 1993, leading to the formation of the current government and the restoration of Prince Sihanouk to power as King in 1993. The Khmer Rouge continued to control portions of western and northern Cambodia until the late 1990s, when they surrendered to government forces in exchange for either amnesty or re-adjustment for positions into the Cambodian government.

In the 21st century, Cambodia's economy has grown faster than that of any other country in Asia except for China and India. Today, post-conflict Cambodia exports over $5 billion worth of clothing, mainly to the United States and the European Union, is one of the top ten exporters of rice in the world, and has seen international tourist arrivals balloon from less than 150,000 in 2000 to over 4.2 million in 2013.

Cambodia is no longer seen as being on the brink of disaster, a reputation it gained in the 1980s and 1990s as guerilla-style warfare was still being waged by the Khmer Rouge until their ceasefire in 1998. Cambodians in the diaspora are returning to their homeland to start businesses, and expatriate Western workers in fields as diverse as architecture, archaeology, philanthropy, banking, hospitality, agriculture, music, diplomacy and garments are increasingly attracted to Cambodia because of its relaxed lifestyle and traditional way of life.

Culture and society

The culture of the ethnic Khmer is fairly homogeneous throughout their geographic range. Regional dialects exist, but are mutually intelligible. The standard is based on the dialect spoken throughout the Central Plain,[28] a region encompassed by the northwest and central provinces. The varieties of Khmer spoken in this region are representative of the speech of the majority of the population. A unique and immediately recognizable dialect has developed in Phnom Penh that, due to the city's status as the national capital, has been modestly affected by recent French and Vietnamese influence.

Other dialects are Northern Khmer dialect, called Khmer Surin by Cambodians, spoken by over a million Khmer native to Northeast Thailand and Khmer Krom spoken by the millions of Khmer native to the Mekong Delta regions of Vietnam adjacent to Cambodia and their descendants abroad. A little-studied dialect known as Western Khmer, or Cardamom Khmer, is spoken by a small, isolated population in the Cardamom Mountain range extending from Cambodia into eastern Central Thailand. Although little studied, it is unique in that it maintains a definite system of vocal register that has all but disappeared in other dialects of modern Khmer.

The modern Khmer strongly identify their ethnic identity with their religious beliefs and practices, which combine the tenets of Theravada Buddhism with elements of indigenous ancestor-spirit worship, animism and shamanism.[12] Most Cambodians, whether or not they profess to be Buddhists (or Muslims), believe in a rich supernatural world. Several types of supernatural entities are believed to exist; they make themselves known by means of inexplicable sounds or happenings. Among these phenomena are khmaoc (ghosts), pret and besach (particularly nasty demons, the spirits of people who have died violent, untimely, or unnatural deaths), arak (evil spirits, usually female), neak ta (tutelary spirits residing in inanimate objects), mneang phteah (guardians of the house), meba (ancestral spirits), and mrenh kongveal (elf-like guardians of animals). All spirits must be shown proper respect, and, with the exception of the mneang phteah and mrenh kongveal, they can cause trouble ranging from mischief to serious life-threatening illnesses.

The majority of the Khmer live in rural villages either as rice farmers or fishermen. Their life revolves around the wat (temple) and the various Buddhist ceremonies throughout the year. However, if Khmers become ill, they will frequently see a kru khmae (shaman/healer), whom they believe can diagnose which of the many spirits has caused the illness and recommend a course of action to propitiate the offended spirit, thereby curing the illness.[29] The kru khmae also is learned in herb lore and is often sought to prepare various "medicines" and potions or for a magical tattoo, all believed to endow one with special prowess and ward off evil spirits or general bad luck.[29] Khmer beliefs also rely heavily on astrology, a remnant of Hinduism. A fortune teller, called hao-ra or kru tieay in Khmer, is often consulted before major events, like choosing a spouse, beginning an important journey or business venture, setting the date for a wedding and determining the proper location for building new structures.

Throughout the year the Khmer celebrate many holidays, most of a religious or spiritual nature, some of which are also observed as public holidays. The two most important are Chol Chnam (Cambodian New Year) and Pchum Ben ("Ancestor Day"). The Khmer Buddhist calendar is divided into 12 months with the traditional new year beginning on the first day of khae chaet, which coincides with the first new moon of April in the western calendar. The modern celebration has been standardized to coincide with April 13.

Khmer culture has influenced Thai and Lao cultures and vice versa. Many Khmer loanwords are found in Thai and Lao, while many Lao and Thai loanwords are found in Khmer. The Thai and Lao alphabets are also derived from the Khmer script.

Immunoglobulin G

Hideo Matsumoto, professor emeritus at Osaka Medical College tested Gm types, genetic markers of immunoglobulin G, of Khmer people for a 2009 study.[31] The study found that the Gm afb1b3 is a southern marker gene possibly originating in southern China and found at high frequencies across southern China, Southeast Asia, Taiwan, Sri Lanka, Bangladesh, Nepal, Assam and parts of the Pacific Islands.[31] The study found that the average frequency of Gm afb1b3 was 76.7% for the Khmer population.[31]
