Pre-history

There exists sparse evidence for a Pleistocene human occupation of present-day Cambodia, which includes quartz and quartzite pebble tools found in terraces along the Mekong River, in Stung Treng and Kratié provinces, and in Kampot Province, although their dating is unreliable. Some slight archaeological evidence shows communities of hunter-gatherers inhabited the region during Holocene: the most ancient archaeological discovery site in Cambodia is considered to be the cave of Laang Spean, in Battambang Province, which belongs to the Hoabinhian period. Excavations in its lower layers produced a series of radiocarbon dates around 6000 BC.^[1] Upper layers in the same site gave evidence of transition to Neolithic, containing the earliest dated earthenware ceramics in Cambodia.

Archaeological records for the period between Holocene and Iron Age remain equally limited. A pivotal event in Cambodian prehistory was the slow penetration of the first rice farmers from the north, which began in the late 3rd millennium BC. The most curious prehistoric evidence in Cambodia are the various "circular earthworks" discovered in the red soils near Memot and in the adjacent region of Vietnam in the latter 1950s. Their function and age are still debated, but some of them possibly date from 2nd millennium BC.

Other prehistoric sites of somewhat uncertain date are Samrong Sen (not far from the ancient capital of Oudong), where the first investigations began in 1875, and Phum Snay, in the northern province of Banteay Meanchey. An excavation at Phum Snay revealed 21 graves with iron weapons and cranial trauma which could point to conflicts in the past, possible with larger cities in Angkor.^[2]

Prehistoric artefacts are often found during mining activities in Ratanakiri.[1]

Iron was worked by about 500 BC, with supporting evidence coming from the Khorat Plateau, in modern-day Thailand. In Cambodia, some Iron Age settlements were found beneath Baksei Chamkrong and other Angkorian temples while circular earthworks at the site of Lovea a few kilometres north-west of Angkor. Burials, much richer than other types of finds, testify to improvement of food availability and trade (even on long distances: in the 4th century BC trade relations with India were already opened) and the existence of a social structure and labour organisation.

Among the artifacts from the Iron Age, glass beads are important evidence. Different kinds of glass beads recovered from several sites across Cambodia, such as the Phum Snay site in the northwest and the Prohear site in the southeast, show that there were two main trading networks at the time. The two networks were separated by time and space, which indicate that there was a shift from one network to the other at about 2nd–4th century AD, probably with changes in socio-political powers.^[3]

Pre-Angkorian and Angkorian era

During the 3rd, 4th, and 5th centuries, the Indianised states of Funan and its successor, Chenla, coalesced in present-day Cambodia and southwestern Vietnam. For more than 2,000 years, what was to become Cambodia absorbed influences from India, passing them on to other Southeast Asian civilisations that are now Thailand and Laos. Little else is known for certain of these polities, however Chinese chronicles and tribute records do make mention of them. It is believed that the territory of Funan may have held the port known to Alexandrian geographer Claudius Ptolemy as "Kattigara". The Chinese chronicles suggest that after Jayavarman I of Chenla died around 681, turmoil ensued which resulted in the division of the kingdom into Land Chenla and Water Chenla which was loosely ruled by weak princes under the dominion of Java.

The Khmer Empire grew out of these remnants of Chenla, becoming firmly established in 802 when Jayavarman II (reigned – ) declared independence from Java and proclaimed himself a Devaraja. He and his followers instituted the cult of the God-king and began a series of conquests that formed an empire which flourished in the area from the 9th to the 15th centuries. During the rule of Jayavarman VIII the Angkor empire was attacked by the Mongol army of Kublai Khan, however, the king was able to buy peace. Around the 13th century, Theravavada missionaries from Sri Lanka reintroduced Theravada Buddhism to Southeast Asia; having sent missionaries previously in 1190s. The religion spread and eventually displaced Hinduism and Mahayana Buddhism as the popular religion of Angkor; however it was not the official state religion until 1295 when Indravarman III took power.

The Khmer Empire was Southeast Asia's largest empire during the 12th century. The empire's centre of power was Angkor, where a series of capitals were constructed during the empire's zenith. In 2007 an international team of researchers using satellite photographs and other modern techniques concluded that Angkor had been the largest pre-industrial city in the world with an urban sprawl of . The city, which could have supported a population of up to one million people and Angkor Wat, the best known and best-preserved religious temple at the site, still serves as a reminder of Cambodia's past as a major regional power. The empire, though in decline, remained a significant force in the region until its fall in the 15th century.

Post-Angkor Period

After a long series of wars with neighbouring kingdoms, Angkor was sacked by the Ayutthaya Kingdom and abandoned in 1432 because of ecological failure and infrastructure breakdown. This led to a period of economic, social, and cultural stagnation when the kingdom's internal affairs came increasingly under the control of its neighbours. By this time, the Khmer penchant for monument building had ceased. Older faiths such as Mahayana Buddhism and the Hindu cult of the god-king had been supplanted by Theravada Buddhism.

The court moved the capital to Longvek where the kingdom sought to regain its glory through maritime trade. The first mention of Cambodia in European documents was in 1511 by the Portuguese. Portuguese travellers described the city as a place of flourishing wealth and foreign trade. Continued wars with Ayutthaya and the Vietnamese resulted in the loss of more territory and Longvek being conquered and destroyed by King Naresuan the Great of Ayutthaya in 1594. A new Khmer capital was established at Oudong south of Longvek in 1618, but its monarchs could survive only by entering into what amounted to alternating vassal relationships with the Siamese and Vietnamese for the next three centuries with only a few short-lived periods of relative independence.

The hill tribe people in Cambodia were "hunted incessantly and carried off as slaves by the Siamese (Thai), the Annamites (Vietnamese), and the Cambodians".

In the nineteenth century, a renewed struggle between Siam and Vietnam for control of Cambodia resulted in a period when Cambodia became the Tây Thành Province of Nguyễn Vietnam, during which Vietnamese officials attempted to force the Khmers to adopt Vietnamese customs. This led to several rebellions against the Vietnamese and appeals to Thailand for assistance. The Siamese–Vietnamese War (1841–1845) ended with an agreement to place the country under joint suzerainty. This later led to the signing of a treaty for French Protection of Cambodia by King Norodom Prohmborirak.

French colonisation

In 1863, King Norodom, who had been installed by Siam,^[4] sought the protection of Cambodia from Siam by French rule. In 1867, Rama IV signed a treaty with France, renouncing suzerainty over Cambodia in exchange for the control of Battambang and Siem Reap provinces which officially became part of Siam. The provinces were ceded back to Cambodia by a border treaty between France and Siam in 1907.

Cambodia continued as a protectorate of France from 1867 to 1953, administered as part of the colony of French Indochina, though occupied by the Japanese empire from 1941 to 1945.^[5] and briefly existing as the puppet state of Kingdom of Kampuchea in mid-1945. Between 1874 and 1962, the total population increased from about 946,000 to 5.7 million. After King Norodom's death in 1904, France manipulated the choice of king, and Sisowath, Norodom's brother, was placed on the throne. The throne became vacant in 1941 with the death of Monivong, Sisowath's son, and France passed over Monivong's son, Monireth, feeling he was too independently minded. Instead, Norodom Sihanouk, a maternal grandson of King Sisowath was enthroned. The French thought young Sihanouk would be easy to control. They were wrong, however, and under the reign of King Norodom Sihanouk, Cambodia gained independence from France on 9 November 1953.^[5]

Independence and Vietnam War

Cambodia became a constitutional monarchy under King Norodom Sihanouk. When French Indochina was given independence, Cambodia lost hope of regaining control over the Mekong Delta as it was awarded to Vietnam. Formerly part of the Khmer Empire, the area had been controlled by the Vietnamese since 1698, with King Chey Chettha II granting the Vietnamese permission to settle in the area decades before. This remains a diplomatic sticking point with over one million ethnic Khmers (the Khmer Krom) still living in this region. The Khmer Rouge attempted invasions to recover the territory which, in part, led to Vietnam's invasion of Cambodia and deposition of the Khmer Rouge.

In 1955, Sihanouk abdicated in favour of his father to participate in politics and was elected prime minister. Upon his father's death in 1960, Sihanouk again became head of state, taking the title of prince. As the Vietnam War progressed, Sihanouk adopted an official policy of neutrality in the Cold War. Sihanouk allowed the Vietnamese communists to use Cambodia as a sanctuary and a supply route for their arms and other aid to their armed forces fighting in South Vietnam. This policy was perceived as humiliating by many Cambodians. In December 1967 Washington Post journalist Stanley Karnow was told by Sihanouk that if the US wanted to bomb the Vietnamese communist sanctuaries, he would not object unless Cambodians were killed.

The same message was conveyed to US President Johnson's emissary Chester Bowles in January 1968. However, in public Sihanouk refuted the right of the U.S. to use air strikes in Cambodia, and on 26 March he said "these criminal attacks must immediately and definitively stop". On 28 March a press conference was held and Sihanouk appealed to the international media: "I appeal to you to publicise abroad this very clear stand of Cambodia—that is, I will, in any case, oppose all bombings on Cambodian territory under whatever pretext." Nevertheless, the public pleas of Sihanouk were ignored and the bombing continued. Members of the government and army became resentful of Sihanouk's ruling style as well as his tilt away from the United States.

Khmer Republic (1970–75)

While visiting Beijing in 1970 Sihanouk was ousted by a military coup led by Prime Minister General Lon Nol and Prince Sisowath Sirik Matak. US support for the coup remains unproven. However, once the coup was completed, the new regime, which immediately demanded that the Vietnamese communists leave Cambodia, gained the political support of the United States. The North Vietnamese and Viet Cong forces, desperate to retain their sanctuaries and supply lines from North Vietnam, immediately launched armed attacks on the new government. The king urged his followers to help in overthrowing this government, hastening the onset of civil war.

Soon Khmer Rouge rebels began using him to gain support. However, from 1970 until early 1972, the Cambodian conflict was largely one between the government and army of Cambodia, and the armed forces of North Vietnam. As they gained control of Cambodian territory, the Vietnamese communists imposed a new political infrastructure, which was eventually dominated by the Cambodian communists now referred to as the Khmer Rouge. Between 1969 and 1973, Republic of Vietnam and US forces bombed Cambodia in an effort to disrupt the Viet Cong and Khmer Rouge.

Documents uncovered from the Soviet archives after 1991 reveal that the North Vietnamese attempt to overrun Cambodia in 1970 was launched at the explicit request of the Khmer Rouge and negotiated by Pol Pot's then second in command, Nuon Chea. NVA units overran many Cambodian army positions while the Communist Party of Kampuchea (CPK) expanded their small-scale attacks on lines of communication. In response to the North Vietnamese invasion, US President Richard Nixon announced that US and South Vietnamese ground forces had entered Cambodia in a campaign aimed at destroying NVA base areas in Cambodia (see Cambodian Incursion). Although a considerable quantity of equipment was seized or destroyed by US and South Vietnamese forces, containment of North Vietnamese forces proved elusive.

The Khmer Republic's leadership was plagued by disunity among its three principal figures: Lon Nol, Sihanouk's cousin Sirik Matak, and National Assembly leader In Tam. Lon Nol remained in power in part because neither of the others was prepared to take his place. In 1972, a constitution was adopted, a parliament elected, and Lon Nol became president. But disunity, the problems of transforming a 30,000-man army into a national combat force of more than 200,000 men, and spreading corruption weakened the civilian administration and army.

The Communist insurgency inside Cambodia continued to grow, aided by supplies and military support from North Vietnam. Pol Pot and Ieng Sary asserted their dominance over the Vietnamese-trained communists, many of whom were purged. At the same time, the CPK forces became stronger and more independent of their Vietnamese patrons. By 1973, the CPK were fighting battles against government forces with little or no North Vietnamese troop support, and they controlled nearly 60% of Cambodia's territory and 25% of its population. The government made three unsuccessful attempts to enter into negotiations with the insurgents, but by 1974, the CPK were operating openly as divisions, and some of the NVA combat forces had moved into South Vietnam. Lon Nol's control was reduced to small enclaves around the cities and main transportation routes. More than 2 million refugees from the war lived in Phnom Penh and other cities.

On New Year's Day 1975, Communist troops launched an offensive which, in 117 days of the hardest fighting of the war, led to the collapse of the Khmer Republic. Simultaneous attacks around the perimeter of Phnom Penh pinned down Republican forces, while other CPK units overran fire bases controlling the vital lower Mekong resupply route. A US-funded airlift of ammunition and rice ended when Congress refused additional aid for Cambodia. The Lon Nol government in Phnom Penh surrendered on 17 April 1975, just five days after the US mission evacuated Cambodia.

Khmer Rouge regime, 1975–1978

The Khmer Rouge reached Phnom Penh and took power in 1975. Led by Pol Pot, they changed the official name of the country to Democratic Kampuchea. The new regime modelled itself on Maoist China during the Great Leap Forward, immediately evacuated the cities, and sent the entire population on forced marches to rural work projects. They attempted to rebuild the country's agriculture on the model of the 11th century, discarded Western medicine, and destroyed temples, libraries, and anything considered Western.

Estimates as to how many people were killed by the Khmer Rouge regime range from approximately one to three million; the most commonly cited figure is two million (about a quarter of the population). This era gave rise to the term Killing Fields, and the prison Tuol Sleng became notorious for its history of mass killing. Hundreds of thousands fled across the border into neighbouring Thailand. The regime disproportionately targeted ethnic minority groups. The Cham Muslims suffered serious purges with as much as half of their population exterminated. Pol Pot was determined to keep his power and disenfranchise any enemies or potential threats, and thus increased his violent and aggressive actions against his people.

Forced repatriation in 1970 and deaths during the Khmer Rouge era reduced the Vietnamese population in Cambodia from between 250,000 and 300,000 in 1969 to a reported 56,000 in 1984.^[6] However, most of the victims of the Khmer Rouge regime were not ethnic minorities but ethnic Khmer. Professionals, such as doctors, lawyers and teachers, were also targeted. According to Robert D. Kaplan, "eyeglasses were as deadly as the yellow star" as they were seen as a sign of intellectualism.

Religious institutions were targeted by the Khmer Rouge particularly fiercely. Religion was so viciously persecuted to such a terrifying extent that the vast majority of Cambodia's historic architecture, 95% of Cambodia's Buddhist temples, was completely destroyed.

Vietnamese occupation and transition, 1978–1992

In November 1978, Vietnamese troops invaded Cambodia in response to border raids by the Khmer Rouge. The People's Republic of Kampuchea (PRK), a pro-Soviet state led by the Kampuchean People's Revolutionary Party, a party created by the Vietnamese in 1951, and led by a group of Khmer Rouge who had fled Cambodia to avoid being purged by Pol Pot and Ta Mok, was established. It was fully beholden to the occupying Vietnamese army and under the direction of the Vietnamese ambassador to Phnom Penh. Its arms came from Vietnam and the Soviet Union.

In opposition to the newly created state, a government-in-exile referred to as the Coalition Government of Democratic Kampuchea (CGDK) was formed in 1981 from three factions.^[7] This consisted of the Khmer Rouge, a royalist faction led by Sihanouk, and the Khmer People's National Liberation Front. Its credentials were recognised by the United Nations. The Khmer Rouge representative to the UN, Thiounn Prasith, was retained, but he had to work in consultation with representatives of the noncommunist Cambodian parties. The refusal of Vietnam to withdraw from Cambodia led to economic sanctions by the US and its allies.

Peace efforts began in Paris in 1989 under the , culminating two years later in October 1991 in a Paris Comprehensive Peace Settlement. The UN was given a mandate to enforce a ceasefire and deal with refugees and disarmament known as the United Nations Transitional Authority in Cambodia (UNTAC).

Modern Cambodia (1993–present)

In 1993, the monarchy was restored with Norodom Sihanouk reinstated as King, and the first post-war election was coordinated by UNTAC. The election was won by FUNCINPEC led by Sihanouk's son Ranariddh in a hung parliament. A power-sharing agreement was agreed with Ranariddh and Hun Sen of the Cambodian People's Party both simultaneously being co-Prime Ministers after the CPP threatened to secede part of the country if power was fully transferred to FUNCINPEC. The stability established following the conflict was shaken in 1997 by a coup d'état led by the co-Prime Minister Hun Sen, who ousted Ranariddh and other parties represented in the government and consolidated power for the CPP. After its government was able to stabilize under Sen, Cambodia was accepted into the Association of Southeast Asian Nations (ASEAN) on 30 April 1999. Norodom Sihamoni was crowned Cambodia's king in 2004 after his father Sihanouk's abdication.

During the late 1990s and early 2000s, reconstruction efforts progressed which led to some political stability through a multiparty democracy under a constitutional monarchy^[8] although Sen's rule has been marred by human rights abuses and corruption. Cambodia's economy grew rapidly in the 2000s and 2010s, and it received considerable investment and infrastructure development support from China as part of its Belt and Road Initiative.A UN-backed war crimes tribunal, the Khmer Rouge Tribunal sought out to investigate crimes committed during the Democratic Kampuchea period and prosecute its leaders. However, Hun Sen has opposed extensive trials or investigations of former Khmer Rouge officials. In July 2010, Kang Kek Iew was the first Khmer Rouge member found guilty of war crimes and crimes against humanity in his role as the former commandant of the S21 extermination camp and he was sentenced to life in prison. In August 2014, the tribunal sentenced Khieu Samphan, the regime's 83-year-old former head of state, and Nuon Chea, its 88-year-old chief ideologue, to life in prison on war crimes charges for their role in the country's terror period in the 1970s.

After the 2013 Cambodian general election, allegations of voter fraud from opposition party Cambodia National Rescue Party led to widespread anti-government protests that continued into the following year. The protests ended after a crackdown by government forces.^[9]

The Cambodia National Rescue Party was dissolved ahead of the 2018 Cambodian general election and the ruling Cambodian People's Party also enacted tighter curbs on mass media. The CPP won every seat in the National Assembly without a major opposition, effectively solidifying de facto one-party rule in the country.

The global COVID-19 pandemic spread to Cambodia in early 2020. Despite minimising the disease's spread for much of 2020 the country's health system was put under strain by a major outbreak in early 2021, which prompted several lockdowns. It also had a severe economic impact, with the tourism industry particularly affected due to international travel restrictions.
