History, geography, religion and culture — essential background for travellers
Cambodia, officially the Kingdom of Cambodia, is a Southeast Asian country bordered by Thailand, Laos, Vietnam and the Gulf of Thailand. Often called the “Kingdom of Wonder,” it draws visitors with Angkor’s temples, colonial towns, tropical islands, rainforests and a culture shaped by Theravada Buddhism and Khmer traditions.
This page summarises the history, landscape and cultural life that form the backdrop to any journey through the country.

Cambodia’s story spans more than two thousand years — from early river kingdoms to the height of Angkor, periods of decline, colonial rule, independence, tragedy in the late 20th century, and recovery as a modern tourism destination.

Khmer royalty and sacred ritual from the Angkor era
Early maritime kingdom in the lower Mekong region, influenced by Indian culture, trade and Hindu-Buddhist ideas. Ports linked China, India and the archipelago.
Successor polities inland along the Mekong and Tonle Sap. Gradual shift toward the political centre that would become Angkor.
Jayavarman II is traditionally credited with unifying the realm and declaring independence from foreign overlordship, founding the Angkorian monarchy.
Capitals at Hariharalaya (Roluos) and later Yasodharapura. Monumental temple-mountains such as Bakong and, later, Pre Rup and East Mebon reflect the devaraja (god-king) cult.
King Suryavarman II builds Angkor Wat as a Hindu temple dedicated to Vishnu. It remains the largest religious monument in the world and the emblem of Cambodia.
Mahayana Buddhist king who expands the empire, builds Angkor Thom, the Bayon (with its famous face towers), Ta Prohm, Preah Khan and an extensive network of roads and rest houses.
Ecological strain, shifting trade, and pressure from neighbouring powers. The court gradually moves toward the Phnom Penh region; Angkor is never fully abandoned but loses primacy.
Capitals at Longvek, then Oudong and Phnom Penh. Cambodia navigates between stronger Siamese and Vietnamese neighbours. Theravada Buddhism becomes firmly established.
France establishes a protectorate. Phnom Penh develops as a colonial capital; Angkor is studied and restored by the École française d’Extrême-Orient. Independence movements grow in the 20th century.
Cambodia gains full independence under King Norodom Sihanouk. A period of relative peace and cultural flourishing follows until the late 1960s.
The monarchy is overthrown; conflict intensifies amid the wider Indochina wars.
Democratic Kampuchea under Pol Pot empties the cities and causes the death of a large part of the population. Sites such as Tuol Sleng and Choeung Ek in Phnom Penh are visited today as memorials.
The regime falls in 1979. A decade of conflict and isolation follows before United Nations-sponsored elections in 1993 and the restoration of the constitutional monarchy.
Political stability returns, Angkor is inscribed as a UNESCO World Heritage Site (1992), and tourism becomes a major part of the economy. Travellers today encounter both the glory of Angkor and the memory of recent history in museums and memorials.
Builder of Angkor Wat (early 12th century). Hindu devotion to Vishnu; the temple later became a Buddhist site.
Mahayana Buddhist monarch behind Angkor Thom, Bayon, Ta Prohm and Preah Khan — many of the most visited temples.
Traditional founder of the independent Khmer Empire (c. 802), associated with the sacred mountain cult at Phnom Kulen.
For visitors: Angkor Archaeological Park (Siem Reap), the National Museum and Royal Palace (Phnom Penh), Oudong, and the genocide memorials provide the main historical experiences on a typical trip.
Cambodia covers about 181,000 km² at the heart of the Indochinese peninsula. Low central plains, the Tonle Sap lake and the Mekong River dominate the interior; mountains and plateaus frame the north, northeast and southwest.

Southeast Asia’s largest freshwater lake. It expands dramatically in the wet season when the Mekong backs up into the lake. Floating villages and bird sanctuaries (such as Prek Toal) are major visitor attractions, usually reached from Siem Reap.
Flows from north to south through Stung Treng, Kratie, Kampong Cham and Phnom Penh. Irrawaddy dolphin watching near Kratie and river life along the banks are popular experiences.
Southwest ranges with rainforest, waterfalls and eco-lodges around Koh Kong and Kampot’s Bokor plateau. Among the most biodiverse areas in mainland Southeast Asia.
Dangrek range (Preah Vihear temple), and the cooler plateaus of Mondulkiri and Ratanakiri — waterfalls, coffee, ethnic minority cultures and nature tourism.
Gulf of Thailand shoreline with Sihanoukville, Kep, Kampot and the islands of Koh Rong and Koh Rong Sanloem — beaches, diving and seafood.
Dry season roughly November–April (peak tourism, cooler evenings Dec wet season May–October (lush landscapes, fewer crowds, afternoon rain). Temperatures are tropical year-round.
Main visitor gateways: Phnom Penh (capital), Siem Reap (Angkor), and Sihanoukville (coast and islands).
Theravada Buddhism is the religion of the large majority of Cambodians and shapes daily life, festivals, art and the rhythm of the calendar. Hindu-Buddhist heritage from the Angkor period remains visible in temple architecture and classical dance.

Traditional music and performance
Pagodas (wat) are community centres as well as places of worship. Monks in saffron robes are a common sight. Visitors are welcome at most temples if they dress modestly (covered shoulders and knees) and remove shoes before entering shrine halls.
Small Muslim (Cham), Christian and other communities. Angkor’s temples began as Hindu or Mahayana Buddhist sanctuaries; their iconography still tells those stories for modern visitors.
Graceful dance rooted in temple art and royal courts. Evening shows in Siem Reap and Phnom Penh are among the most popular cultural experiences.
Pinpeat ensembles accompany ceremony and dance. Sbek thom (large shadow puppets) dramatise epic stories.
Silk weaving (including Silk Island near Phnom Penh), silverwork, wood and stone carving, krama scarves and lacquerware — widely available in markets and workshops.
Balanced sweet, sour, salty and bitter flavours. Signature dishes: fish amok, lok lak, nom banh chok, samlor soups, and Kampot pepper with seafood. Street food and markets are part of the travel experience.
Khmer New Year (April), Pchum Ben (ancestor festival, Sep/Oct), and Water Festival (Bon Om Touk) in Phnom Penh (Oct/Nov) are the main events travellers may encounter. Dates follow the lunar calendar.
Modest dress at temples; ask before photographing people; avoid touching monks’ robes (especially for women); feet should not point at sacred images or people. A respectful “sompeah” greeting (palms together) is appreciated.
Cambodia is a constitutional monarchy. The capital is Phnom Penh. For travellers, the most relevant points are entry requirements, currency and local regulations.
