This history of Cambodia from World War II up to the Vietnamese invasion in 1979 focuses on the devastating revolution that convulsed the country under Pol Pot between 1975 and 1979, and the civil war that preceded it. David Chandler offers an analysis of the chaos during the 1970s and an understanding of events in the previous quartercentury. Drawing on vast quantities of primary material (including his own reports for the US embassy while a foreign service officer in Phnom Penh), on interviews, and on the scholarly literature, Chandler considers why the revolution happened, how it related to Cambodia's earlier history and to other events in southeast Asia, why it took the course it did, who was responsible for it, and to what extent its ideology drew on foreign rather than Cambodian elements.
