Kingdom of Cambodia
The Kingdom of Cambodia (pronounced /kæmˈboʊdiə/, formerly known as Kampuchea (/kæmpuːˈtʃiːə/), 
, transliterated: Preăh Réachéanachâkr Kâmpŭchea) is a country in South East Asia with a population of over 14 million people. The kingdom's capital and largest city is Phnom Penh. Cambodia is the successor state of the once powerful Hindu and Buddhist Khmer Empire, which ruled most of the Indochinese Peninsula between the eleventh and fourteenth centuries.
A citizen of Cambodia is usually identified as "Cambodian" or "Khmer," though the latter strictly refers to ethnic Khmers. Most Cambodians are Theravada Buddhists of Khmer extraction, but the country also has a substantial number of predominantly Muslim Cham, as well as ethnic Chinese, Vietnamese and small animist hill tribes.
The country borders Thailand to its west and northwest, Laos to its northeast, and Vietnam to its east and southeast. In the south it faces the Gulf of Thailand. The geography of Cambodia is dominated by the Mekong river (colloquial Khmer: Tonle Thom or "the great river") and the Tonlé Sap ("the fresh water lake"), an important source of fish. Its culture is heavily influenced by Thailand and Laos.
Cambodia's main industries are garments, tourism, and construction. In 2007, foreign visitors to Angkor Wat numbered more than 4 million. In 2005, oil and natural gas deposits were found beneath Cambodia's territorial water, and once commercial extraction begins in 2011, the oil revenues could profoundly affect Cambodia's economy
The first advanced civilizations in present-day Cambodia appeared in the 1st millennium AD. During the 3rd, 4th, and 5th centuries, the Indianised states of Funan and Chenla coalesced in what is now present-day Cambodia and southwestern Vietnam. These states, which are assumed by most scholars to have been Khmer, had close relations with China and Thailand. Their collapse was followed by the rise of the Khmer Empire, a civilization which flourished in the area from the 9th century to the 13th century.
The Khmer Empire declined yet remained powerful in the region until the 15th century. The empire's center of power was Angkor, where a series of capitals was constructed during the empire's zenith. Angkor Wat, the most famous and best-preserved religious temple at the site, is a reminder of Cambodia's past as a major regional power.
After a long series of wars with neighbouring kingdoms, Angkor was sacked by the Thai and abandoned in 1432. The court moved the capital to Lovek where the kingdom sought to regain its glory through maritime trade. The attempt was short-lived, however, as continued wars with the Thai and Vietnamese resulted in the loss of more territory and the conquering of Lovek in 1594. During the next three centuries, The Khmer kingdom alternated as a vassal state of the Thai and Vietnamese kings, with short-lived periods of relative independence between.
In 1863 King Norodom, who had been installed by Thailand, sought the protection of France from the Thai and Vietnamese, after tensions grew between them. 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 1906.
Cambodia continued as a protectorate of France from 1863 to 1953, administered as part of the colony of French Indochina. After war-time occupation by the Japanese empire from 1941 to 1945, Cambodia gained independence from France on November 9, 1953. It became a constitutional monarchy under King Norodom Sihanouk.
In 1955, Sihanouk abdicated in favour of his father in order to be 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 until Cambodians began to take sides, and ousted in 1970 by a military coup led by Prime Minister General Lon Nol and Prince Sisowath Sirik Matak, while on a trip abroad. From Beijing, Sihanouk realigned himself with the communist Khmer Rouge rebels who had been slowly gaining territory in the remote mountain regions and urged his followers to help in overthrowing the pro-United States government of Lon Nol, hastening the onset of civil war.
Operation Menu, a series of secret B-52 bombing raids by the United States on alleged Viet Cong bases and supply routes inside Cambodia, was acknowledged after Lon Nol assumed power; U.S. forces briefly invaded Cambodia in a further effort to disrupt the Viet Cong. The bombing continued and, as the Cambodian communists began gaining ground, eventually included strikes on suspected Khmer Rouge sites until halted in 1973.
Some two million Cambodians were made refugees by the bombing and fighting and fled to Phnom Penh. Estimates of the number of Cambodians killed during the bombing campaigns vary widely. Views of the effects of the bombing also vary widely. The US Seventh Air Force argued that the bombing prevented the fall of Phnom Penh in 1973 by killing 16,000 of 25,500 Khmer Rouge fighters besieging the city. Journalist William Shawcross and Cambodia specialists Milton Osborne, David P. Chandler and Ben Kiernan argued that the bombing drove peasants to join the Khmer Rouge. Chandler writes that the bombing provided "the psychological ingredients of a violent, vengeful and unrelenting social revolution." Cambodia specialist Craig Etcheson argued that it is "untenable" to assert that the Khmer Rouge would not have won but for US intervention, and that while the bombing did help Khmer Rouge recruitment, they "would have won anyway."
As the war ended, a draft US AID report observed that the country faced famine in 1975, with 75% of its draft animals destroyed by the war, and that rice planting for the next harvest would have to be done "by the hard labor of seriously malnourished people." The report predicted that
without large-scale external food and equipment assistance there will be widespread starvation between now and next February... Slave labor and starvation rations for half the nation's people (probably heaviest among those who supported the republic) will be a cruel necessity for this year, and general deprivation and suffering will stretch over the next two or three years before Cambodia can get back to rice self-sufficiency.
The Khmer Rouge reached Phnom Penh and took power in 1975, changing the official name of the country to Democratic Kampuchea, led by Pol Pot. The Regime, heavily influenced and backed by China, 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. They discarded Western medicine, destroyed temples, libraries, and anything considered western. Any person with trained skills, doctors, lawyers, teachers, were especially targeted. With that result, hundreds of thousands died from starvation and disease there were almost no drugs in the country.
