Cambodia

The Country of Angkor — and the Country of the Khmer Rouge

Cambodia’s modern identity is shaped by two opposing realities. Angkor Wat — the largest religious monument in the world, the centre of the Khmer Empire (802-1431) that controlled much of mainland Southeast Asia — represents one of human civilisation’s greatest architectural achievements. The Khmer Rouge regime (1975-1979) under Pol Pot represents one of the 20th century’s worst genocides — an estimated 1.5-2 million Cambodians (roughly 25% of the population) were killed through execution, forced labour, starvation, or disease. The country is still navigating the gap between these two heritages, with a population whose median age is now under 28 — meaning most Cambodians have no personal memory of the Khmer Rouge era.

Modern Cambodia is one of Southeast Asia’s poorest countries but has been growing at 7% annually for two decades. The country has been governed continuously by Hun Sen (1985-2023, then his son Hun Manet since August 2023) — one of the world’s longest-ruling leaders. Cambodia is officially a constitutional monarchy under King Norodom Sihamoni, though political power resides with the prime minister.

A Brief History

The Khmer Empire

Cambodia’s medieval Khmer Empire dominated mainland Southeast Asia for over 600 years (9th-15th centuries). At its peak under King Jayavarman VII (r. 1181-1218), the empire extended from modern Vietnam through Laos, Thailand, and into Burma. The capital city of Angkor had perhaps 750,000 to 1 million people in the 13th century — making it the largest pre-industrial city in the world.

Decline and Foreign Rule

The empire declined through the 15th century, with the capital moving to Phnom Penh after the sack of Angkor by the Ayutthayan Siamese in 1431. Over subsequent centuries, Cambodia was caught between Siamese and Vietnamese expansion. French colonisation (1863-1953) brought Cambodia into the French Indochina federation.

Independence and the Khmer Rouge

Independence in 1953 under King Norodom Sihanouk. The country was drawn into the Vietnam War through US bombing campaigns (1969-1973) that destabilised the country. The Khmer Rouge, a Maoist Communist movement led by Pol Pot, captured Phnom Penh on 17 April 1975 and immediately emptied the cities, abolished money, and began a four-year campaign of forced agricultural labour and political extermination that killed 1.5-2 million people.

Vietnamese invasion in 1979 ended Khmer Rouge rule. UN-organised elections in 1993 restored constitutional government. The current monarchy was restored.

The Hun Sen Era

Hun Sen dominated Cambodian politics from 1985 to 2023 — 38 years, among the longest tenures of any modern world leader. His son Hun Manet took over the prime ministership in August 2023.

Geography and Climate

Cambodia covers 181,035 km² — about the size of Oklahoma — dominated by the Mekong River valley, the Tonlé Sap Lake (Southeast Asia’s largest freshwater lake), and the Cardamom Mountains in the southwest.

Climate

Tropical monsoon — wet season May-October, dry season November-April.

Culture, Language and Religion

Khmer is the official language. Theravada Buddhism is practised by about 95% of the population.

The Economy

Cambodia has a lower-middle-income economy (~$32 billion GDP in 2024). Key sectors: garment manufacturing (the country’s largest export sector), tourism (5+ million visitors pre-pandemic, recovering), agriculture (rice, rubber).

Cuisine

Cambodian (Khmer) cuisine is delicate and herbaceous, less spicy than Thai:

• Amok — fish curry steamed in banana leaf with coconut milk
• Nom banh chok — Cambodian breakfast noodles in fish-based green curry
• Bai sach chrouk — pork on rice, the standard breakfast
• Lok lak — stir-fried beef cubes with lime-pepper dipping sauce

Nature and UNESCO Sites

Cambodia has 4 UNESCO World Heritage Sites: Angkor, Preah Vihear (a hilltop temple on the Thai border), Sambor Prei Kuk (a 7th-century capital city), and the Koh Ker archaeological site (added 2023).
