From Prisoners of Class: A Historical Memoir of the Khmer Rouge Revolution, by Chan Samoeun, tr. by Matthew Madden (Mekong River Press, 2023), Kindle pp. 11-12:
Cambodia is a small Southeast Asian kingdom, bordered by Vietnam on the east, Thailand on the west and north, and Laos to the north. Its primary religion is Theravada Buddhism. Its main ethnic majority are referred to as Khmers, and the national language is Khmer. The capital city, sitting at the confluence of the Mekong and Sap rivers, is called Phnom Penh.
The kingdom was colonized by France for nearly a century, from 1863 until 1953 when it secured full independence from France under the leadership of King Norodom Sihanouk. Sihanouk abdicated the throne a year later to take a leading role in Cambodian electoral politics, which he dominated for the next fifteen years as a popular and powerful head of state.
On 18 March 1970, Sihanouk was deposed in a parliamentary coup by his prime minister, General Lon Nol. This seminal event broke Sihanouk’s long and carefully maintained neutrality that had kept Cambodia out of the Vietnam War raging next door, as Lon Nol immediately aligned with the United States against the communists, causing the conflict to spill over into Cambodia.
Thus began a bloody civil war, as Lon Nol founded the Khmer Republic, notoriously corrupt and heavily funded by United States military aid; and the embittered Sihanouk, with Chinese support, publicly allied himself with the Cambodian faction of communists, dubbed (by him) the “Khmer Rouge,” in an armed resistance against the new government. Hoping for a return to power, Sihanouk allowed himself to be made the nominal figurehead of this armed resistance, and because he was highly revered by many Cambodians, especially in the countryside, this decision lent tremendous influence and strength to the Khmer Rouge in recruiting large-scale support from the Cambodian populace.
Five years of violent conflict and devastating national division led, ultimately, to an imminent Khmer Rouge victory in mid-April 1975. As Khmer Rouge forces surrounded Phnom Penh for the final battle against disintegrating government forces and prepared to capture the city, the city’s population eagerly awaited the end of the war and the return of peace.
