|Although Cambodia had a rich and powerful past under the Hindu state of Funan and the Kingdom of Angkor, by the mid-19th century the country was on the verge of dissolution. After repeated requests for French assistance, a protectorate was established in 1863. By 1884, Cambodia was a virtual colony; soon after it was made part of the Indochina Union with Annam, Tonkin, Cochin-China, and Laos. France continued to control the country even after the start of World War II through its Vichy government. In 1945, the Japanese dissolved the colonial administration, and King Norodom Sihanouk declared an independent, anti-colonial government under Prime Minister Son Ngoc Thanh in March 1945. The Allies deposed this government in October. In January 1953, Sihanouk named his father as regent and went into self-imposed exile, refusing to return until Cambodia gained genuine independence.
Sihanouk's actions hastened the French Government's July 4, 1953 announcement of its readiness to grant independence, which came on November 9, 1953. The situation remained uncertain until a 1954 conference was held in Geneva to settle the French-Indochina war. All participants, except the United States and the State of Vietnam, associated themselves (by voice) with the final declaration. The Cambodian delegation agreed to the neutrality of the three Indochinese states but insisted on a provision in the cease-fire agreement that left the Cambodian Government free to call for outside military assistance should the Viet Minh or others threaten its territory.
Neutrality was the central element of Cambodian foreign policy during the 1950s and 1960s. By the mid-1960s, parts of Cambodia's eastern provinces were serving as bases for North Vietnamese Army and Viet Cong (NVA/VC) forces operating against South Vietnam, and the port of Sihanoukville was being used to supply them. As NVA/VC activity grew, the United States and South Vietnam became concerned, and in 1969, the United States began a series of air raids against NVA/VC base areas inside Cambodia.
Throughout the 1960s, domestic politics polarized. Opposition grew within the middle class and among leftists, including Paris-educated leaders such as Son Sen, Ieng Sary, and Saloth Sar (later known as Pol Pot), who led an insurgency under the clandestine Communist Party of Kampuchea (CPK).
The Khmer Republic and the War
In March 1970, Gen. Lon Nol deposed Prince Sihanouk and assumed power. On October 9, the Cambodian monarchy was abolished, and the country was renamed the Khmer Republic. Hanoi rejected the new republic's request for the withdrawal of NVA/VC troops and began to reinfiltrate some of the 2,000-4,000 Cambodians who had gone to North Vietnam in 1954. They became a cadre in the insurgency. The United States moved to provide material assistance to the new government's armed forces, which were engaged against both the Khmer Rouge insurgents and NVA/VC forces. In April 1970, U.S. and South Vietnamese forces entered Cambodia in a campaign aimed at destroying NVA/VC base areas. Although a considerable quantity of equipment was seized or destroyed, NVA/VC forces proved elusive and moved deeper into Cambodia. NVA/VC units overran many Cambodian Army positions while the Khmer Rouge expanded their smallscale attacks on lines of communication.
The Khmer Republic's leadership was plagued by disunity among its leadership, the problems of transforming a 30,000-man army into a national combat force of more than 200,000 men, and spreading corruption. The insurgency continued to grow, with supplies and military support provided by North Vietnam. But inside Cambodia, Pol Pot and Ieng Sary asserted their dominance over the Vietnamese-trained communists, many of whom were purged. At the same time, the Khmer Rouge forces became stronger and more independent of their Vietnamese patrons. By 1974, 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 that, in 117 days of the hardest fighting of the war, destroyed the Khmer Republic. Simultaneous attacks around the perimeter of Phnom Penh pinned down Republican forces, while other Khmer Rouge units overran fire bases controlling the vital lower Mekong resupply route. A U.S.-funded airlift of ammunition and rice ended when Congress refused additional aid for Cambodia. Phnom Penh surrendered on April 17--5 days after the U.S. mission evacuated Cambodia.
Many Cambodians welcomed the arrival of peace, but the Khmer Rouge soon turned Cambodia--which it called Democratic Kampuchea (DK)--into a land of horror. Immediately after its victory, the new regime ordered the evacuation of all cities and towns, sending the entire urban population out into the countryside to till the land. Thousands starved or died of disease during the evacuation. Many of those forced to evacuate the cities were resettled in new villages, which lacked food, agricultural implements, and medical care. Many starved before the first harvest, and hunger and malnutrition--bordering on starvation--were constant during those years. Those who resisted or who questioned orders were immediately executed, as were most military and civilian leaders of the former regime who failed to disguise their pasts.
Within the CPK, the Paris-educated leadership--Pol Pot, Ieng Sary, Nuon Chea, and Son Sen--was in control, and Pol Pot was made prime minister. Prince Sihanouk was put under virtual house arrest. The new government sought to restructure Cambodian society completely. Remnants of the old society were abolished, and Buddhism suppressed.
Agriculture was collectivized, and the surviving part of the industrial base was abandoned or placed under state control. Cambodia had neither a currency nor a banking system. The regime controlled every aspect of life and reduced everyone to the level of abject obedience through terror. Torture centers were established, and detailed records were kept of the thousands murdered there. Public executions of those considered unreliable or with links to the previous government were common. Few succeeded in escaping the military patrols and fleeing the country. Solid estimates of the numbers who died between 1975 and 1979 are not available, but it is likely that hundreds of thousands were brutally executed by the regime. Hundreds of thousands more died of starvation and disease (both under the Khmer Rouge and during the Vietnamese invasion in 1978). Estimates of the dead range from 1.7 to 3 million, out of a 1975 population estimated at 7.3 million.
Democratic Kampuchea's relations with Vietnam and Thailand worsened rapidly as a result of border clashes and ideological differences. While communist, the CPK was fiercely anti-Vietnamese, and most of its members who had lived in Vietnam were purged. Democratic Kampuchea established close ties with China, and the Cambodian-Vietnamese conflict became part of the Sino-Soviet rivalry, with Moscow backing Vietnam. Border clashes worsened when Democratic Kampuchea's military attacked villages in Vietnam.
In mid-1978, Vietnamese forces invaded Cambodia, advancing about 30 miles before the arrival of the rainy season. In December 1978, Vietnam announced formation of the Kampuchean United Front for National Salvation (KUFNS) under Heng Samrin, a former DK division commander. It was composed of Khmer communists who had remained in Vietnam after 1975 and officials from the eastern sector--like Heng Samrin and Hun Sen--who had fled to Vietnam from Cambodia in 1978. In late December 1978, Vietnamese forces launched a full invasion of Cambodia, capturing Phnom Penh on January 7 and driving the remnants of Democratic Kampuchea's Army westward toward Thailand.
The Vietnamese Occupation
On January 10, 1979, the Vietnamese installed Heng Samrin as head of state in the new People's Republic of Kampuchea (PRK). The Vietnamese Army continued its pursuit of Pol Pot's Khmer Rouge forces. At least 600,000 Cambodians displaced during the Pol Pot era and the Vietnamese invasion began streaming to the Thai border in search of refuge.
The international community responded with a massive relief effort coordinated by the United States through UNICEF and the World Food Program. More than $400 million was provided between 1979 and 1982, of which the United States contributed nearly $100 million. At one point, more than 500,000 Cambodians were living along the Thai-Cambodian border and more than 100,000 in holding centers inside Thailand.
Vietnam's occupation army of as many as 200,000 troops controlled the major population centers and most of the countryside from 1979 to September 1989. The Heng Samrin regime's 30,000 troops were plagued by poor morale and widespread desertion. Resistance to Vietnam's occupation continued. A large portion of the Khmer Rouge's military forces eluded Vietnamese troops and established themselves in remote regions. The non-communist resistance, consisting of a number of groups which had been fighting the Khmer Rouge after 1975--including Lon Nol-era soldiers--coalesced in 1979-80 to form the Khmer People's National Liberation Armed Forces (KPNLAF), which pledged loyalty to former Prime Minister Son Sann, and Moulinaka (Movement pour la Liberation Nationale de Kampuchea), loyal to Prince Sihanouk. In 1979, Son Sann formed the Khmer People's National Liberation Front (KPNLF) to lead the political struggle for Cambodia's independence. Prince Sihanouk formed his own organization, FUNCINPEC, and its military arm, the Armee Nationale Sihanoukienne (ANS) in 1981.
Within Cambodia, Vietnam had only limited success in establishing its client Heng Samrin regime, which was dependent on Vietnamese advisers at all levels. Security in some rural areas was tenuous, and major transportation routes were subject to interdiction by resistance forces. The presence of Vietnamese throughout the country and their intrusion into nearly all aspects of Cambodian life alienated much of the populace. The settlement of Vietnamese nationals, both former residents and new immigrants, further exacerbated anti-Vietnamese sentiment. Reports of the numbers involved vary widely with some estimates as high as 1 million. By the end of this decade, Khmer nationalism began to reassert itself against the traditional Vietnamese enemy. In 1986, Hanoi claimed to have begun withdrawing part of its occupation forces. At the same time, Vietnam continued efforts to strengthen its client regime, the PRK, and its military arm, the Kampuchean People's Revolutionary Armed Forces (KPRAF). These withdrawals continued over the next 2 years, and the last Vietnamese troops left Cambodia in September 1989.
From July 30 to August 30, 1989, representatives of 18 countries, the four Cambodian parties, and the UN Secretary General met in Paris in an effort to negotiate a comprehensive settlement. They hoped to achieve those objectives seen as crucial to the future of post-occupation Cambodia--a verified withdrawal of the remaining Vietnamese occupation troops, the prevention of the return to power of the Khmer Rouge, and genuine self-determination for the Cambodian people. A comprehensive settlement was agreed upon on August 28, 1990.
On October 23, 1991, the Paris Conference reconvened to sign a comprehensive settlement giving the UN full authority to supervise a cease-fire, repatriate the displaced Khmer along the border with Thailand, disarm and demobilize the factional armies, and to prepare the country for free and fair elections. Prince Sihanouk, President of the Supreme National Council of Cambodia (SNC), and other members of the SNC returned to Phnom Penh in November 1991, to begin the resettlement process in Cambodia. The UN Advance Mission for Cambodia (UNAMIC) was deployed at the same time to maintain liaison among the factions and begin demining operations to expedite the repatriation of approximately 370,000 Cambodians from Thailand.
On March 16, 1992, the UN Transitional Authority in Cambodia (UNTAC) arrived in Cambodia to begin implementation of the UN Settlement Plan. The UN High Commissioner for Refugees began fullscale repatriation in March 1992. UNTAC grew into a 22,000-strong civilian and military peacekeeping force to conduct free and fair elections for a constituent assembly.
Over four million Cambodians (about 90% of eligible voters) participated in the May 1993 elections, although the Khmer Rouge or Party of Democratic Kampuchea (PDK), whose forces were never actually disarmed or demobilized, barred some people from participating. Prince Ranariddh's FUNCINPEC Party was the top vote recipient with a 45.5% vote followed by Hun Sen's Cambodian People's Party and the Buddhist Liberal Democratic Party, respectively. FUNCINPEC then entered into a coalition with the other parties that had participated in the election. The parties represented in the 120-member Assembly proceeded to draft and approve a new Constitution, which was promulgated September 24. It established a multiparty liberal democracy in the framework of a constitutional monarchy, with the former Prince Sihanouk elevated to King. Prince Ranariddh and Hun Sen became First and Second Prime Ministers, respectively, in the Royal Cambodian Government (RGC). The Constitution provides for a wide range of internationally recognized human rights.
Compared to its recent past, the 1993-2003 period has been one of relative stability for Cambodia. However, political violence continues to be a problem in there. In 1997, factional fighting between supporters of Prince Norodom Ranariddh and Hun Sen broke out, resulting in more than 100 FUNCINPEC deaths and a few CPP casualties. Some FUNCINPEC leaders were forced to flee the country, and Hun Sen took over as Prime Minister. FUNCINPEC leaders returned to Cambodia shortly before the 1998 National Assembly elections. In those elections, the CPP received 41% of the vote, FUNCINPEC 32%, and the Sam Rainsy Party (SRP) 13%. Due to political violence, intimidation, and lack of media access, many international observers judged the elections to have been seriously flawed. The CPP and FUNCINPEC formed another coalition government, with CPP the senior partner. Cambodia's first commune elections were held in February 2002. These elections to select chiefs and members of 1,621 commune (municipality) councils also were marred by political violence and fell short of being free and fair by international standards. The election results were largely acceptable to the major parties, though procedures for the new local councils have not been fully implemented.
A riot occurred in January 2003 in which the Embassy of Thailand and several Thai businesses were damaged. Following the incident, Prime Minister Hun Sen expressed the RGC's regret to the Thai Government and promised compensation.
