Cambodians have enjoyed a long and often triumphant history. Anybody who witnesses the magnificent temples at Angkor can attest to the fact that the Khmer Empire was once wealthy, militarized, and a major force in the region. Its zenith came under Jayavarman VII (1181-ca. 1218), where the Empire made significant territorial gains from the Cham. The Khmer Empire stretched to encompass parts of modern day Thailand, Malaysia, Burma, Laos and Vietnam. The period following the fall of the Khmer Empire has been described as Cambodia’s dark ages. Climatic factors precipitated this fall, where the Ankorian civilization harnessed Cambodia’s water for agriculture through elaborate systems of canals and dams. The Khmer Empire never recovered from the sacking by its neighbours, based in Ayutthaya (in modern day Thailand), and Cambodia spent much of the next 400 years until French colonization squeezed and threatened by the rivalries of the expanding Siamese and Vietnamese Empires to the West and East. Indeed, on the eve of French colonization it was claimed that Cambodia was likely set to cease to exist as an independent kingdom entirely, with the historian John Tully claiming “there can be little doubt that their [the French] intervention prevented the political disappearance of the kingdom”.
