• 1. Ancient Origins And Khmer Empire

  ›

  In 802 AD, Jayavarman II declared himself king and united the warring Khmer princes of Chenla under the name Kambuja. This declaration marked the beginning of the Khmer Empire, which grew to become Southeast Asia's largest empire during the 12th century. The empire's center of power was Angkor, where a series of capitals were constructed during its zenith. In 2007, an international team of researchers using satellite photographs concluded that Angkor had been the largest pre-industrial city in the world with an urban sprawl supporting up to one million people. The Indianized kingdom facilitated the spread of first Hinduism and then Buddhism to Southeast Asia. Around the 13th century, Theravada missionaries from Sri Lanka reintroduced Theravada Buddhism to the region. The religion eventually displaced Hinduism as the popular religion of Angkor, though it did not become the official state religion until 1295 when Indravarman III took power. During the rule of Jayavarman VIII, the Angkor empire was attacked by the Mongol army of Kublai Khan, but the king managed to buy peace. By the 15th century, the empire began a decline in power, leading to the abandonment of Angkor in 1432 due to ecological failure and infrastructure breakdown.

• 2. Colonial Rule And Independence Struggle

  In 1863, King Norodom signed a treaty of protection with France, establishing a French protectorate that lasted until 1953. This period included a brief interruption while the kingdom was 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, placing Sisowath, Norodom's brother, on the throne. The throne became vacant in 1941 with the death of Monivong, Sisowath's son. France passed over Monivong's son, Monireth, feeling he was too independently minded. Instead, Norodom Sihanouk, a maternal grandson of King Sisowath, was enthroned. Under the reign of King Norodom Sihanouk, Cambodia gained independence from France on the 9th of November 1953. 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.

• 3. Civil War And The Killing Fields

  ›

  While visiting Beijing in 1970, Sihanouk was ousted by a military coup led by Prime Minister General Lon Nol and Prince Sisowath Sirik Matak. Once the coup was completed, the new regime demanded that Vietnamese communists leave Cambodia and gained political support from the United States. From 1970 until 1972, the Cambodian conflict was largely between the government and army of Cambodia and the armed forces of North Vietnam. On New Year's Day 1975, Communist troops launched an offensive which, in 117 days, led to the collapse of the Khmer Republic. The Lon Nol government in Phnom Penh surrendered on the 17th of April 1975, five days after the US mission evacuated Cambodia. Estimates as to how many people were killed by the Khmer Rouge regime range from approximately one to three million, with a cited figure of two million representing about a quarter of the population. This era gave rise to the term Killing Fields, and the prison Tuol Sleng became known for its history of mass killing. Hundreds of thousands fled across the border into neighboring Thailand. The regime disproportionately targeted ethnic minority groups, including Cham Muslims whose population was reduced by half.

• 4. Peace Processes And Modern Politics

  ›

  In November 1978, Vietnamese troops invaded Cambodia in response to border raids by the Khmer Rouge and conquered it. 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 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). 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 CPP.

• 5. Geography And Environmental Challenges

  ›

  Cambodia has an area of approximately 181,035 square kilometers and lies entirely within the tropics between latitudes 10° and 15°N. It borders Thailand to the north and west, Laos to the northeast, and Vietnam to the east and southeast. The most distinctive geographical feature is the inundations of the Tonle Sap, measuring about 2,560 square kilometers during the dry season and expanding to about 14,000 square kilometers during the rainy season. This densely populated plain is devoted to wet rice cultivation and serves as the heartland of Cambodia. In 2020, forest cover was around 46% of the total land area, equivalent to 8,068,370 hectares, down from 11,004,790 hectares in 1990. The rate of deforestation in Cambodia is one of the highest in the world, with primary forest cover falling from over 70% in 1969 to just 3.1% in 2007. Plans for hydroelectric development in the Greater Mekong Subregion pose a real danger to the food supply of Vietnam and Cambodia.

  The garment industry represents the largest portion of Cambodia's manufacturing sector, accounting for 80% of the country's exports. In 2012, exports grew to $4.61 billion up 8% over 2011. Tourism receipts exceeded US$4.4 billion in 2018, accounting for almost ten percent of the kingdom's gross national product. International visitor arrivals in 2023 topped 5.4 million based on the Tourism Statistics Report published by the Minister of Tourism. Tourism employs 26% of the country's workforce, which translates into roughly 2.5 million jobs for Cambodians. Since the early 2020s, Cambodia has become a major base for large-scale online scam operations run from guarded compounds. A 2023 UN human-rights report estimated that around 100,000 people in Cambodia were held in scam operations. In October 2025, the U.S. Department of Justice filed what it described as the largest forfeiture action in its history, seeking forfeiture of approximately 127,271 bitcoin tied to a case alleging forced-labor scam compounds.

  The majority of Cambodia's population is of ethnic Khmer origin at 95.8%, who are speakers of the Khmer language, the country's sole official language. Theravada Buddhism is the official religion of Cambodia, practiced by more than 95 per cent of the population with an estimated 4,392 monastery temples throughout the country. Bon Om Touk, the annual boat rowing contest, is the most attended Cambodian national festival. Approximately 10% of Cambodia's population attends this event each year to play games, give thanks to the moon, watch fireworks, dine, and attend the boat race in a carnival-type atmosphere. Every year, Cambodians visit pagodas across the country to mark the Pchum Ben festival during which people offer prayers and food to the spirits of their dead relatives. Rice is the staple grain, while fish from the Mekong and Tonlé Sap rivers form part of the diet. Khmer classical dance is the form of stylized performance art established in the royal courts of Cambodia exhibited for both entertainment and ceremonial purposes.
