This collection provides a window into the political, social, and economic development of Cambodia, the rapidly maturing ���modern��� state in the heart of Southeast Asia. Traced here is the critical legacy of Prince Norodom Sihanouk (1922-2012), the nation���s controversial and paradoxical leader. Khmer nationalism, loyalty to the monarch, struggle against injustice and corruption, and protection of the Buddhist religion were at the forefront of developments in this period. The archive is an essential resource for the study of Southeast Asian history and the U.S. role in the war in Vietnam. The files are arranged according to the classification system of U.S. State Department Records, and they cover a wide range of internal political affairs.
