Year Zero

When the Khmer Rouge entered Phnom Penh on the morning of April 17, 1975, many of the city's residents came into the streets to watch. The civil war had lasted five years and killed hundreds of thousands, and many residents hoped it was over. Some waved white flags of surrender. Some brought food and flowers. The black-clad soldiers — many of them teenagers who had grown up in the jungle and never seen a city — walked through the streets without smiling, without speaking. Within hours, it became clear that this was not a liberation. Loudspeakers mounted on trucks announced that all residents must leave immediately. American bombing was claimed as the reason. The evacuation would be only a few days. It was never a few days.

The ideology that drove the evacuation was called 'Year Zero.' Cambodia's new rulers — a secretive collective known as 'Angkar' (The Organization) — believed that modern society was irredeemably corrupt: cities, money, trade, religion, formal education, Western medicine, foreign languages, even eyeglasses — all were markers of the old world that had to be destroyed so a new agrarian utopia could be built from scratch. The Khmer Rouge had not invented this ideology in isolation; it drew on Maoist agrarianism, French communist anti-colonialism, and a romantic nationalism that imagined Cambodia returning to the glory of the Angkor empire. What made it uniquely lethal was its totalism. There would be no partial revolution. Everything would be erased.

The evacuation of Phnom Penh was the most dramatic act in the history of communist revolution — and the most immediately murderous. Approximately 2.5 million people were driven onto roads in the April heat with no food, water, or medical care. Hospital patients were pushed out on their hospital beds; some were still on operating tables. The elderly who could not walk were left at roadsides. Families were separated at checkpoints, never to reunite. Khmer Rouge cadres — most of them young men and women from rural peasant backgrounds — enforced the evacuation with automatic weapons. Shooting a straggler was not an aberration; it was policy. Tens of thousands died in the first week.

The city they left behind became a ghost. Phnom Penh in 1975 — a bustling capital of 2.5 million, with restaurants, markets, universities, hospitals, cinemas — was emptied in days. Buildings were left with food on the tables, cars in the streets, doors open. The Khmer Rouge had no use for cities. They were ideological pollution. Money was dumped in piles and burned. The national bank was blown up. Temples were turned into prisons or warehouses. Schools were converted to torture chambers. The entire apparatus of modern civilization that Cambodia had built over generations was deliberately, systematically, and irreversibly destroyed in a matter of weeks.
