The Kingdom of Cambodia (Preah Reacheanachak Kampuchea — ព្រះរាជាណាចក្រកម្ពុជា), is located in the southern portion of the Indochina Peninsula in Southeast Asia. It is 69,898 square miles (181,035 square kilometers) in area, bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east, and the Gulf of Thailand to the southwest. Cambodia has a population of over 15 million. The official religion is Theravada Buddhism, practiced by approximately 95 percent of the population. The capital and largest city is Phnom Penh, the political, economic, and cultural center of Cambodia. The kingdom is a constitutional monarchy with Norodom Sihamoni, a monarch chosen by the Royal Throne Council, as head of state. The head of government is Hun Sen, who is currently the longest serving non-royal leader in South East Asia and has ruled Cambodia for over 25 years.
The English “Cambodia” is an anglicization of the French “Cambodge”, which in turn is the French transliteration of the Khmer Kampuchea which derives from the Sanskrit name Kambujadeśa (कम्बोजदेश), composed of देश, desa (“land of” or “country of”) and कम्बोज, Kambujas, which alludes to the foundation myths of the first ancient Khmer kingdom. Colloquially, Cambodians refer to their country as either Srok Khmer, meaning “Khmer’s Land”, or the slightly more formal Prateh Kampuchea (ប្រទេសកម្ពុជា), literally “Country of Kampuchea”. The name “Cambodia” is used most often in the Western world while “Kampuchea” is more widely used in the East.
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 the Holocene Era. The most ancient archaeological discovery site in Cambodia is considered to be the cave of L’aang Spean, in Battambang Province, which belongs to the Hoabinhian period. Excavations in its lower layers produced a series of radiocarbon dates of 6000 B.C. 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 B.C. 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 the second millennium B.C.
Iron was worked by about 500 B.C., 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, were found beneath Lovea a few miles northwest of Angkor. Burials, much richer than other types of finds, testify to improvement of food availability and trade (even on long distances: in the fourth century B.C., trade relations with India were already opened) and the existence of a social structure and labor organization. Different kinds of glass beads recovered from several sites across Cambodia, such as the Phum Snay site in northwest and the Prohear site in 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 sccond–fourth century A.D., probably with changes in socio-political powers.
During the third, fourth, and fifth centuries, the Indianized 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 civilizations 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 690, turmoil ensued which resulted in 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 c790-850) 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 fifteenth 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 thirteenth century, monks from Sri Lanka introduced Theravada Buddhism to Southeast Asia. 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 twelfth century. The empire’s center 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 1,150 square miles (2,978 square kilometers). 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 serve as reminders 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 fifteenth century.
After a long series of wars with neighboring 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 neighbors. 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 travelers described the city as a place of flourishing wealth and foreign trade. The attempt was short-lived however, as 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 Anamites (Vietnamese), and the Cambodians.”
In the nineteenth century a renewed struggle between Siam and Vietnam for control of Cambodia resulted in a period when 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.
In 1863 Cambodia became a protectorate of France which doubled the size of the country by reclaiming the north and west from Thailand. King Norodom, who had been installed by Thailand, had sought the protection of France from the Thai rule. In 1867, the Thai king 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 Thailand. The provinces were ceded back to Cambodia by a border treaty between France and Thailand in 1907.
French Indochina was formed in October 1887 from Annam, Tonkin, Cochinchina (which together form modern Vietnam) and the Kingdom of Cambodia; Laos was added after the Franco-Siamese War in 1893. 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. 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 November 9, 1953.
The first stamps inscribed with ROYAUME DU CAMBODGE had actually been issued prior to independence in 1951-1952 (Scott #1-17), replacing the Indochina stamps it had been using since 1892.
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 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 favor 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 President Lyndon Johnson’s emissary Chester Bowles in January 1968. However, in public Sihanouk refuted the United States’ right to use air strikes in Cambodia and on March 26, Prince Sihanouk said “these criminal attacks must immediately and definitively stop…” On March 28, a press conference was held and Sihanouk appealed to the international media “I appeal to you to publicize 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.
While visiting Beijing in 1970 Sihanouk was ousted by a military coup led by Prime Minister General Lon Nol and Prince Sisowath Sirik Matak. U.S. 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 we now refer 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, U.S. President Richard Nixon announced that United States and South Vietnamese ground forces had entered Cambodia in a campaign aimed at destroying NVA base areas in Cambodia. Although a considerable quantity of equipment was seized or destroyed by U.S. 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, collapsed 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 April 17, 1975, just five days after the US mission evacuated Cambodia.
The National United Front of Kampuchea took over Cambodia in 1975 and established Democratic Kampuchea, led by Pol Pot, The new regime modeled 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. The new regime allowed no civilian private communication and so abolished the postal system.
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 neighboring 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. 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.
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 direction of the Vietnamese ambassador to Phnom Penh. Its arms came from Vietnam and the Soviet Union. Postal service resumed in early 1979 when the Vietnam People’s Army drove the Khmer Rouge out of the capital Phnom Penh.
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. 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 United Nations, 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 U.S. and its allies.
Peace efforts began in Paris in 1989 under the State of Cambodia, culminating two years later in October 1991 in a Paris Comprehensive Peace Settlement. The U.N. was given a mandate to enforce a ceasefire and deal with refugees and disarmament known as the United Nations Transitional Authority in Cambodia (UNTAC).
In 1993, Norodom Sihanouk was restored as King of Cambodia, but all power was in the hands of the government established after the UNTAC sponsored elections. The stability established following the conflict was shaken in 1997 by a coup d’état led by the co-Prime Minister Hun Sen against the non-communist parties in the government. In recent years, reconstruction efforts have progressed and led to some political stability through a multiparty democracy under a constitutional monarchy.
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. However, Hun Sen has opposed extensive trials of former Khmer Rouge mass murderers.
In August 2014, a U.N.-backed war crimes tribunal, the Extraordinary Chambers in the Courts of Cambodia (also known as the Khmer Rouge 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. The trial began in November 2011. Former Foreign Minister Ieng Sary died in 2013, while his wife, Social Affairs Minister Ieng Thirith, was deemed unfit to stand trial due to dementia in 2012. The group’s top leader, Pol Pot, died in 1998.
Scott #1543 was released on July 30, 1996, the 1500 rial denomination in a series designed to promote historic Cambodian sites. A total of seven stamps portraying different scenes from the Ta Prohm of Bati were released on that day and a further seven with Angkor Wat as their subject appeared on March 26, 1997. This is one of several temples built in Cambodia and Thailand during the reign of Jayavarman VII to house the Jayabuddhamahanatha statues and is located close to Tonle Bati, a small lake about 30 kilometers south of Phnom Penh,
