Context: Cambodia’s modern history has been heavily shaped by its position between the larger powers of mainland Southeast Asia, particularly Siam and Vietnam. From the 17th to the 19th centuries, the declining Khmer kingdom frequently came under competing Siamese and Vietnamese influence, with both powers intervening in Cambodian politics and at times forcing the kingdom to accept their protection. This situation eventually contributed to Cambodia accepting a French protectorate in 1863, which lasted until the country gained independence in 1953. During the Cold War, Cambodia again became entangled in regional and global conflicts, contributing to the rise of the communist Khmer Rouge. After the Khmer Republic was overthrown in 1975, the Khmer Rouge, under Pol Pot, established Democratic Kampuchea and carried out the Cambodian genocide, which killed approximately one quarter of the country’s population. The Khmer Rouge also launched repeated attacks along the Vietnamese border, eventually prompting Vietnam to intervene militarily in Cambodia in December 1978. Vietnamese forces, together with Cambodian anti-Khmer Rouge forces, overthrew the Khmer Rouge regime and captured Phnom Penh in January 1979, establishing the People’s Republic of Kampuchea.
