Phnom Penh is the capital and most populous city of Cambodia. It has been the national capital since 1865 and has grown to become the nation's primate city and its political, economic, industrial, and cultural centre. The city's name derives from Wat Phnom, a Buddhist temple, and Lady Penh, the city's founder. It sits at the confluence of the Tonlé Sap and Mekong rivers, and is the start of the Bassac River. It is also the seat of Cambodia's monarchy, based at the Royal Palace.

Founded in 1372, Phnom Penh succeeded Angkor Thom as the national capital in 1434 following the fall of Angkor, and remained so until 1497. It regained its capital status during the French colonial era. It underwent a period of investment and modernization during Cambodia's independence period, earning the nickname the "Pearl of Asia" for its colonial French, New Khmer and Art Deco architecture. The city's population swelled in the 1960s and 1970s as refugees fled from civil war and American bombing during the Vietnam War. Phnom Penh's entire population was forcibly evacuated in 1975 by the Khmer Rouge, and faced persecution, forced labour and genocide. Phnom Penh remained largely uninhabited during the Democratic Kampuchea era until Vietnam-backed forces took the city in 1979. The city was reconstructed and infrastructure improved in the modern era with the support of international investment and aid. By 2009, it was home to more than 2 million people, approximately 14% of the Cambodian population.

The Greater Phnom Penh area includes the nearby Ta Khmau city and some districts of Kandal province. The city formerly functioned as a processing center, with textiles, pharmaceuticals, machine manufacturing, and rice milling. Its cultural institutions and events have made it a hub for domestic and international tourism. The city has hosted regional and international events, including the 2002, 2012, and 2014 ASEAN Summit, the 32nd Southeast Asian Games, and the 12th ASEAN Para Games. Phnom Penh will be the first Cambodian city and the second city in Southeast Asia to host the Asian Youth Games in 2031.

Etymology Phnom Penh () takes its name from the Wat Phnom (), or from the Funan Kingdom, which existed from the 1st to the 7th century AD in Southeast Asia and was the forerunner of the Cambodian monarchy. Legend has it that in 1372, a wealthy widow named Penh found a Koki tree floating down the Tonlé Sap River after a storm.

Phnom Penh's former official name is Krong Chaktomuk Serei Mongkol (, lit. "city of Brahma's faces"), in its short form as Krong Chaktomuk (). Krong Chaktomuk is an abbreviation of the full name, given to it by King Ponhea Yat: Krong Chaktomuk Mongkol Sakal Kampuchea Thipadei Serei Theakreak Bavar Intabat Borei Roat Reach Seima Moha Nokor ( ). This loosely translates as "the place of four rivers that gives the happiness and success of the Khmer Kingdom, the highest leader as well as impregnable city of the God Indra of the great kingdom".

History The initial settlement of Phnom Penh is believed to have been established since the 5th century AD, according to the discovery of kiln site in Choeung Ek commune of Dangkao district, southern part of central Phnom Penh in the 2000s. Choeung Ek archaeological site was one of the largest kiln pottery center in Cambodia and the earliest known kiln sites in Southeast Asia to produce the ceremonial vessels known as kendi from 5th to 13th century. Archaeologists stated that a large community is surrounded by a circular earthwork structure that is 740 metres in diameter and 4 metres high, built in the 11th century. There are remnants of other village infrastructure, irrigation system, inscription, Shiva linga and a brick temple foundation and its ornate remains which dated back to Funan era.

First recorded a century after it is said to have taken place, the legend of the founding of Phnom Penh tells of a local woman, Penh (also referred to as Daun Penh (Lady Penh in Khmer), living at Chaktomuk, the future Phnom Penh. It was the 14th century, and the Khmer capital was still at Angkor near Siem Reap to the north. Gathering firewood along the banks of the river, Lady Penh spied a floating koki tree in the river and fished it from the water. Inside the tree she found four Buddha statues and one of Vishnu.

The discovery was taken as a divine blessing, and to some a sign that the Khmer capital was to be brought to Phnom Penh from Angkor. To house the new-found sacred objects, Penh raised a hill on the west bank of the Tonle Sap River and crowned it with a shrine, later known as Wat Phnom at the north end of central Phnom Penh. "Phnom" is Khmer for "hill" and Penh's hill took on the name of the founder, and the area around it became known after the hill.

Phnom Penh first became the capital of Cambodia after Ponhea Yat (c. 1390 – 1463), king of the Khmer Empire, moved the capital from Angkor Thom after it was captured and destroyed by Siam years earlier. There is a stupa. In the 17th century, Japanese immigrants settled on the outskirts of what later is Phnom Penh. A Portuguese community survived in Phnom Penh until the 17th century, undertaking commercial and religious activity in the country.

Phnom Penh remained the royal capital for 73 years, from 1432 to 1505. It was abandoned for 360 years (from 1505 to 1865) by subsequent kings due to internal fighting between the royal pretenders. Later kings moved the capital several times and established their royal capitals at locations in Tuol Basan (Srey Santhor), Pursat, Longvek, Lavear Em and Oudong. From 1673 to 1674, Phnom Penh was the stronghold of rebel king Kaev Hua II.

During the Vietnam War, Cambodia was used as a base by the People's Army of Vietnam and the Viet Cong, and thousands of refugees from across the country flooded the city to escape the fighting between their own government troops, the People's Army of Vietnam, the Viet Cong, the South Vietnamese and their allies, the Khmer Rouge, and American air strikes. By 1975, the population was 2–3 million, the bulk of whom were refugees from the fighting.Stuart-Fox, William, The Murderous Revolution: Life & Death in Pol Pot's Kampuchea, Alternative Publishing Co-Operative Limited, 1985, pp. 17. The Khmer Rouge cut off supplies to the city for more than a year before it fell on 17 April 1975. Reports from journalists stated that the Khmer Rouge shelling "tortured the capital almost continuously", inflicting "random death and mutilation" on millions of trapped civilians.Barron, John and Anthony Paul (1977), Murder of a Gentle Land, Reader's Digest Press, pp. 1–2. The Khmer Rouge forcibly evacuated the entire city after taking it, in what has been described as a death march: François Ponchaud wrote that "I shall never forget one cripple who had neither hands nor feet, writhing along the ground like a severed worm, or a weeping father carrying his ten-year old daughter wrapped in a sheet tied around his neck like a sling, or the man with his foot dangling at the end of a leg to which it was attached by nothing but skin";Ponchaud, Francois (1978), Cambodia Year Zero, Holt, Rinehart and Winston, pp. 6–7. Jon Swain recalled that the Khmer Rouge were "tipping out patients from the hospitals like garbage into the streets....In five years of war, this is the greatest caravan of human misery I have seen".Swain, John (1999), River of Time: A Memoir of Vietnam and Cambodia, Berkley Trade. All of its residents, including the wealthy and educated, were evacuated from the city and forced to do difficult labour on rural farms as "new people".Stuart-Fox, pp. 7.

The Khmer Rouge were driven out of Phnom Penh by the People's Army of Vietnam in 1979, and people began to return to the city. A period of reconstruction began, spurred by the continuing stability of government, attracting new foreign investment and aid by countries including France, Australia, and Japan. Loans were made from the Asian Development Bank and the World Bank to reinstate a clean water supply, roads and other infrastructure. The 1998 Census put Phnom Penh's population at 862,000;General Population Census of Cambodia 1998, National Institute of Statistics, Ministry of Planning, Phnom Penh, Cambodia and the 2008 census was 1.3 million.Cambodian 2008 census preliminary results, Statistics Japan 2–6, Tables 2.2–2.6 By 2019, its population reached over 2.2 million, based on general population census.

Geography

Phnom Penh is in the south-central region of Cambodia, and is fully surrounded by the Kandal province. The municipality is on the banks of the Tonlé Sap, Mekong, and Bassac Rivers. These rivers provide freshwater and other natural resources to the city. Phnom Penh and the surrounding areas consist of a typical flood plain area for Cambodia. While Phnom Penh is at above the river, monsoon season flooding is a problem, and the river sometimes overflows its banks. Boeung Kak, Phnom Penh's largest freshwater lake, was controversially filled in 2010 to make way for property development.

Climate Phnom Penh has a tropical wet and dry climate (Köppen climate classification Aw). The climate is hot year-round with only minor variations. Temperatures typically range from and weather is subject to the tropical monsoons. The southwest monsoon blows inland bringing moisture-laden winds from the Gulf of Thailand and Indian Ocean from May to November, sees high temperatures accompanied by high humidity. The dry season lasts from December to April; when overnight temperatures can drop to .
