The History of Cambodia

No one knows for certain how long people have lived in what is now Cambodia, as studies of its prehistory are undeveloped. A carbon-l4 dating from a cave in northwestern Cambodia suggests that people using stone tools lived in the cave as early as 4000 bc, and rice has been grown on Cambodian soil since well before the 1st century ad. The first Cambodians likely arrived long before either of these dates. They probably migrated from the north, although nothing is known about their language or their way of life.

By the beginning of the 1st century ad, Chinese traders began to report the existence of inland and coastal kingdoms in Cambodia. These kingdoms already owed much to Indian culture, which provided alphabets, art forms, architectural styles, religions (Hinduism and Buddhism), and a stratified class system. Local beliefs that stressed the importance of ancestral spirits coexisted with the Indian religions and remain powerful today.

Cambodia’s modem-day culture has its roots in the 1st to 6th centuries in a state referred to as Funan, known as the oldest Indianized state in Southeast Asia. It is from this period that evolved Cambodia’s language, part of the Mon-Khmer family, which contains elements of Sanskrit, its ancient religion of Hinduism and Buddhism. Historians have noted, for example, that Cambodians can be distinguished from their neighbors by their clothing – checkered scarves known as Kramas are worn instead of straw hats.

Funan gave way to the Angkor Empire with the rise to power of King Jayavarman II in 802. The following 600 years saw powerful Khmer kings dominate much of present day Southeast Asia, from the borders of Myanmar east to the South China Sea and north to Laos. It was during this period that Khmer kings built the most extensive concentration of religious temples in the world – the Angkor temple complex. The most successful of Angkor’s kings, Jayavarman II, Indravarman I, Suryavarman II and Jayavarman VII, also devised a masterpiece of ancient engineering: a sophisticated irrigation system that includes barays (gigantic man-made lakes) and canals that ensured as many as three rice crops a year. Part of this system is still in use today.

The Khmer Kingdom (Funan)

Early Chinese writers referred to a kingdom in Cambodia that they called Funan. Modern-day archaeological findings provide evidence of a commercial society centered on the Mekong Delta that flourished from the 1st century to the 6th century. Among these findings are excavations of a port city from the 1st century, located in the region of Oc-Eo in what is now southern Vietnam. Served by a network of canals, the city was an important trade link between India and China. Ongoing excavations in southern Cambodia have revealed the existence of another important city near the present-day village of Angkor Borei.

A group of inland kingdoms, known collectively to the Chinese as Zhenla, flourished in the 6th and 7th centuries from southern Cambodia to southern Laos. The first stone inscriptions in the Khmer language and the first brick and stone Hindu temples in Cambodia date from the Zhenla period.

Angkor Era

Bayon Temple, Angkor Thom The giant faces carved on the Bayon temple at the Angkor Thum complex in northwestern Cambodia represent both the Buddha and King Jayavarman VII (ruled about 1130-1219). Although a Buddhist temple, Angkor Thum was modeled after the great Hindu temple complex of Angkor Wat.

In the early 9th century a Khmer (ethnic Cambodian) prince returned to Cambodia from abroad. He probably arrived from nearby Java or Sumatra, where he may have been held hostage by island kings who had asserted control over portions of the Southeast Asian mainland.

In a series of ceremonies at different sites, the prince declared himself ruler of a new independent kingdom, which unified several local principalities. His kingdom eventually came to be centered near present-day Siemreab in northwestern Cambodia. The prince, known to his successors as Jayavarman II, inaugurated a cult honoring the Hindu god Shiva as a devaraja (Sanskrit term meaning “god-king”). The cult, which legitimized the king’s rule by linking him with Shiva, persisted at the Cambodian court for more than two hundred years.

Between the early 9th century and the early 15th century, 26 monarchs ruled successively over the Khmer kingdom (known as Angkor, the modern name for its capital city).

The successors of Jayavarman II built the great temples for which Angkor is famous.

Historians have dated more than a thousand temple sites and over a thousand stone inscriptions (most of them on temple walls) to this era.

Notable among the Khmer builder-kings were Suyavarman II, who built the temple known as Angkor Wat in the mid-12th century, and Jayavarman VII, who built the Bayon temple at Angkor Thum and several other large Buddhist temples half a century later. Jayavarman VII, a fervent Buddhist, also built hospitals and rest houses along the roads that crisscrossed the kingdom. Most of the monarchs, however, seem to have been more concerned with displaying and increasing their power than with the welfare of their subjects.

Ancient City of Angkor This map shows the layout of the ancient city of Angkor, capital of the Cambodian Khmer kingdom from the 9th century to the 15th century. The city’s huge stone temples were both civic centers and religious symbols of the Hindu cosmos. Historians believe that Angkor’s network of canals and barays (reservoirs) were used for irrigation.

At its greatest extent, in the 12th century, the Khmer kingdom encompassed (in addition to present-day Cambodia) parts of present-day Vietnam, Laos, Thailand, Myanmar (formerly Burma), and the Malay Peninsula. Thailand and Laos still contain Khmer ruins and inscriptions. The kings at Angkor received tribute from smaller kingdoms to the north, east, and west, and conducted trade with China. The capital city was the center of an impressive network of reservoirs and canals, which historians theorize supplied water for irrigation. Many historians believe that the abundant harvests made possible by irrigation supported a large population whose labor could be drawn on to construct the kings’ temples and to fight their wars. The massive temples, extensive roads and waterworks, and confident inscriptions give an illusion of stability that is undermined by the fact that many Khmer kings gained the throne by conquering their predecessors. Inscriptions indicate that the kingdom frequently suffered from rebellions and foreign invasions.

Historians have not been able to fully explain the decline of the Khmer kingdom in the 13th and 14th centuries. However, it was probably associated with the rise of powerful Thai kingdoms that had once paid tribute to Angkor, and to population losses following a series of wars with these kingdoms. Another factor may have been the introduction of Theravada Buddhism, which taught that anyone could achieve enlightenment through meritorious conduct and meditation. These egalitarian ideas undermined the hierarchical structure of Cambodian society and the power of prominent Hindu families. After a Thai invasion in 1431, what remained of the Cambodian elite shifted southeastward to the vicinity of Phnom Penh.

Cambodia Dark Age

This map of Southeast Asia in the mid-16th century shows the major centers of power in the region prior to the arrival of Europeans. During this period, these kingdoms were constantly at war. Eventually the Kingdom of Ayutthaya (modern Thailand) expanded to the north and east, absorbing much of Lan Na and Lan Xang (modern Laos). Dai Viet (modern Vietnam) expanded to the south, taking over the remaining territory of the Kingdom of Champa and the southern tip of the Kingdom of Lovek (modern Cambodia). Toungoo evolved into modern Myanmar.

The four centuries of Cambodian history following the abandonment of Angkor are poorly recorded, and therefore historians know little about them beyond the bare outlines. Cambodia retained its language and its cultural identity despite frequent invasions by the powerful Thai kingdom of Ayutthaya and incursions by Vietnamese forces. Indeed, for much of this period, Cambodia was a relatively prosperous trading kingdom with its capital at Lovek, near present-day Phnom Penh. European visitors wrote of the Buddhist piety of the inhabitants of the Kingdom of Lovek. During this period, Cambodians composed the country’s most important work of literature, the Reamker (based on the Indian myth of the Ramayana).

In the late 18th century, a civil war in Vietnam and disorder following a Burmese invasion of Ayutthaya spilled over into Cambodia and devastated the area. In the early 19th century, newly established dynasties in Vietnam and Thailand competed for control over the Cambodian court. The warfare that ensued, beginning in the l830s, came close to destroying Cambodia.

French Rule

Phnom Penh, as planned by the French, came to resemble a town in provincial France. By the second half of the 19th century, France had begun to expand its colonial penetration of Indochina (the peninsula between India and China). In 1863 France accepted the Cambodian king’s invitation to impose a protectorate over his severely weakened kingdom, halting the country’s dismemberment by Thailand and Vietnam. For the next 90 years, France ruled Cambodia. In theory, French administration was indirect, but in practice the word of French officials was final on all major subjects-including the selection of Cambodia’s kings. The French left Cambodian institutions, including the monarchy, in place, and gradually developed a Cambodian civil service, organized along French lines. The French administration neglected education but built roads, port facilities, and other public works. Phnom Penh, as planned by the French, came to resemble a town in provincial France.

The French invested relatively little in Cambodia’s economy compared to that of Vietnam, which was also under French control. However, they developed rubber plantations in eastern Cambodia, and the kingdom exported sizable amounts of rice under their rule. The French also restored the Angkor temple complex and deciphered Angkorean inscriptions, which gave Cambodians a clear idea of their medieval heritage and kindled their pride in Cambodia’s past. Because France left the monarchy, Buddhism, and the rhythms of rural life undisturbed, anti-French feeling was slow to develop.

King Sihanouk, through skillful maneuvering, managed to gain Cambodia’s independence peacefully in 1953. During World War II (1939-1945), Japanese forces entered French Indochina but left the compliant French administration in place.

On the verge of defeat in 1945, the Japanese removed their French collaborators and installed a nominally independent Cambodian government under the recently crowned young king, Norodom Sihanouk. France reimposed its protectorate in early 1946 but allowed the Cambodians to draft a constitution and to form political parties.

Soon afterward, fighting erupted throughout Indochina as nationalist groups, some with Communist ideologies, struggled to win independence from France. Most of the fighting took place in Vietnam, in a conflict known as the First Indochina War (1946-1954). In Cambodia, Communist guerrilla forces allied with Vietnamese Communists gained control of much of the country. However, King Sihanouk, through skillful maneuvering, managed to gain Cambodia’s independence peacefully in 1953, a few months earlier than Vietnam. The Geneva Accords of 1954, which marked the end of the First Indochina War, acknowledged Sihanouk’s government as the sole legitimate authority in Cambodia.

Modern State

Sihanouk’s campaign for independence sharpened his political skills and increased his ambitions. In 1955 he abdicated the throne in favor of his father to pursue a full-time political career, free of the constitutional constraints of the monarchy. In a move aimed at dismantling Cambodia’s fledgling political parties, Sihanouk inaugurated a national political movement known as the Sangkum Reastr Niyum (People’s Socialist Community), whose members were not permitted to belong to any other political group. The Sangkum won all the seats in the national elections of 1955, benefiting from Sihanouk’s popularity and from police brutality at many polling stations. Sihanouk served as prime minister of Cambodia until 1960, when his father died and he was named head of state. Sihanouk remained widely popular among the people but was brutal to his opponents.

In the late 1950s the Cold War (period of tension between the United States and its allies and the Union of Soviet Socialist Republics, or USSR, and its allies) intensified in Asia. In this climate, foreign powers, including the United States, the USSR, and China, courted Sihanouk. Cambodia’s importance to these countries stemmed from events in neighboring Vietnam, where tension had begun to mount between a Communist regime in the north and a pro-Western regime in the south. The USSR supported the Vietnamese Communists, while the United States opposed them, and China wanted to contain Vietnam for security reasons. Each of the foreign powers hoped that Cambodian support would bolster its position in the region. Sihanouk pursued a policy of neutrality that drew substantial economic aid from the competing countries.

In 1965, however, Sihanouk broke off diplomatic relations with the United States. At the same time, he allowed North Vietnamese Communists, then fighting the Vietnam War against the United States and the South Vietnamese in southern Vietnam, to set up bases on Cambodian soil. As warfare intensified in Vietnam, domestic opposition to Sihanouk from both radical and conservative elements increased. The Cambodian Communist organization, known as the Workers Party of Kampuchea (later renamed the Communist Party of Kampuchea, or CPK), had gone underground after failing to win any concessions at the Geneva Accords, but now they took up arms once again. As the economy became unstable, Cambodia became difficult to govern single-handedly. In need of economic and military aid, Sihanouk renewed diplomatic relations with the United States. Shortly thereafter, in 1969, U.S. president Richard Nixon authorized a bombing campaign against Cambodia in an effort to destroy Vietnamese Communist sanctuaries there.

Khmer Republic

In March 1970 Cambodia’s legislature, the National Assembly, deposed Sihanouk while he was abroad. The conservative forces behind the coup were pro-Western and anti-Vietnamese. General Lon Nol, the country’s prime minister, assumed power and sent his poorly equipped army to fight the North Vietnamese Communist forces encamped in border areas. Lon Nol hoped that U.S. aid would allow him to defeat his enemies, but American support was always geared to events in Vietnam. In April U.S. and South Vietnamese troops invaded Cambodia, searching for North Vietnamese, who moved deeper into Cambodia. Over the next year, North Vietnamese troops destroyed the offensive capacity of Lon Nol’s army.

In October 1970 Lon Nol inaugurated the Khmer Republic. Sihanouk, who had sought asylum in China, was condemned to death despite his absence. By that time, Chinese and North Vietnamese leaders had persuaded the prince to establish a government in exile, allied with North Vietnam and dominated by the CPK, whom Sihanouk referred to as the Khmer Rouge (French for “Red Khmers”).

In 1975, despite massive infusions of U.S. aid, the Khmer Republic collapsed, and Khmer Rouge forces occupied Phnom Penh.

The United States continued bombing Cambodia until the Congress of the United States halted the campaign in 1973. By that time, Lon Nol’s forces were fighting not only the Vietnamese but also the Khmer Rouge. The general lost control over most of the Cambodian countryside, which had been devastated by U.S. bombing. The fighting severely damaged the nation’s infrastructure and caused high numbers of casualties. Hundreds of thousands of refugees flooded into the cities. In 1975, despite massive infusions of U.S. aid, the Khmer Republic collapsed, and Khmer Rouge forces occupied Phnom Penh. Three weeks later, North Vietnamese forces achieved victory in South Vietnam.

Democratic Kampuchea

Pol Pot Pol Pot is a pseudonym for the Cambodian guerrilla commander Saloth Sar, who organized the Communist guerrilla force known as the Khmer Rouge. The Khmer Rouge ousted General Lon Nol in 1975, establishing a brutal Communist regime that ruled until 1979.

Immediately after occupying Cambodia’s towns, the Khmer Rouge ordered all city dwellers into the countryside to take up agricultural tasks. The move reflected both the Khmer Rouge’s contempt for urban dwellers, whom they saw as enemies, and their utopian vision of Cambodia as a nation of busy, productive peasants. The leader of the regime, who remained concealed from the public, was Saloth Sar, who used the pseudonym Pol Pot. The government, which called itself Democratic Kampuchea (DK), claimed to be seeking total independence from foreign powers but accepted economic and military aid from its major allies, China and North Korea.

Khmer Rouge Carnage The Khmer Rouge, led by Pol Pot, killed close to 1.7 million people in the mid- to late 1970s. In this photo, human bones and skulls fill a museum in Cambodia that had been used as a prison and torture center during Pol Pot’s reign, Sygma.

Without identifying themselves as Communists, the Khmer Rouge quickly introduced a series of far-reaching and often painful socialist programs. The people given the most power in the new government were the largely illiterate rural Cambodians who had fought alongside the Khmer Rouge in the civil war. DK leaders severely restricted freedom of speech, movement, and association, and forbade all religious practices. The regime controlled all communications along with access to food and information. Former city dwellers, now called “new people,” were particularly badly treated. The Khmer Rouge killed intellectuals, merchants, bureaucrats, members of religious groups, and any people suspected of disagreeing with the party. Millions of other Cambodians were forcibly relocated, deprived of food, tortured, or sent into forced labor.

While in power, the Khmer Rouge murdered, worked to death, or killed by starvation close to 1.7 million Cambodians.

The Khmer Rouge also attacked neighboring countries in an attempt to reclaim territories lost by Cambodia many centuries before. After fighting broke out with Vietnam (then united under the Communists) in 1977, DK’s ideology became openly racist. Ethnic minorities in Cambodia, including ethnic Chinese and Vietnamese, were hunted down and expelled or massacred. Purges of party members accused of treason became widespread. People in eastern Cambodia, suspected of cooperating with Vietnam, suffered severely, and hundreds of thousands of them were killed. While in power, the Khmer Rouge murdered, worked to death, or killed by starvation close to 1.7 million Cambodians-more than one-fifth of the country’s population.

Recent Development

In October 1991 Cambodia’s warring factions, the UN, and a number of interested foreign nations signed an agreement in Paris intended to end the conflict in Cambodia. The agreement provided for a temporary power-sharing arrangement between a United Nations Transitional Authority in Cambodia (UNTAC) and a Supreme National Council (SNC) made up of delegates from the various Cambodian factions. Prince Norodom Sihanouk, the former king and prime minister of Cambodia, served as president of the SNC.

The Paris accords and the UN protectorate pushed Cambodia out of its isolation and introduced competitive politics, dormant since the early 1950s. UNTAC sponsored elections for a national assembly in May 1993, and for the first time in Cambodian history a majority of voters rejected an armed, incumbent regime. A royalist party, known by its French acronym FUNCINPEC, won the most seats in the election, followed by the CPP, led by Hun Sen. Reluctant to give up power, Hun Sen threatened to upset the election results. Under a compromise arrangement, a three-party coalition formed a government headed by two prime ministers; FUNCINPEC’s Prince Norodom Ranariddh, one of Sihanouk’s sons, became first prime minister, while Hun Sen became second prime minister.

In September 1993 the government ratified a new constitution restoring the monarchy and establishing the Kingdom of Cambodia. Sihanouk became king for the second time. After the 1993 elections, no foreign countries continued to recognize the DK as Cambodia’s legal government. The DK lost its UN seat as well as most of its sources of international aid.

The unrealistic power-sharing relationship between Ranariddh and Hun Sen worked surprisingly well for the next three years, but relations between the parties were never smooth. The CPP’s control over the army and the police gave the party effective control of the country, and it dominated the coalition government. In July 1997 Hun Sen staged a violent coup against FUNCINPEC and replaced Prince Ranariddh, who was overseas at the time, with Ung Huot, a more pliable FUNCINPEC figure. Hun Sen’s action shocked foreign nations and delayed Cambodia’s entry into the Association of Southeast Asian Nations (ASEAN). By the end of 1997, Cambodia was the only nation in the region that was not a member.

Despite the coup, elections scheduled for July 1998 proceeded as planned. Hundreds of foreign observers who monitored the elections affirmed that voting was relatively free and fair; however, the CPP harassed opposition candidates and party workers before and after the elections, when dozens were imprisoned and several were killed. The election gave the CPP a plurality of votes, but results, especially in towns, where voting could not be dictated by local authorities, indicated that the party did not enjoy widespread popular support. Prince Ranariddh and another opposition candidate, Sam Rainsy, took refuge abroad and contested the outcome of the election. In November the CPP and FUNCINPEC reached an agreement whereby Hun Sen became sole prime minister and Ranariddh became president of the National Assembly. The parties formed a coalition government, dividing control over the various cabinet ministries. In early 1999 the constitution was amended to create a Senate, called for in the 1998 agreement. These signs that Cambodia’s political situation was stabilizing encouraged ASEAN to admit Cambodia to its membership a short time later.

Pol Pot died in 1998, and by early 1999 most of the remaining Khmer Rouge troops and leaders had surrendered. Rebel troops were integrated into the Cambodian army. In 1999 two Khmer Rouge leaders were arrested and charged with genocide for their part in the atrocities.

Since the Paris Accords of 1991, Cambodia’s economic growth has depended on millions of dollars of foreign aid. Foreign interest in Cambodia has decreased, however, and the country has received diminishing economic assistance. This development, along with the continued lack of openness in Cambodian politics, has made Cambodia’s prospects for democratization dim, as well as its chances for sustained economic growth.
