Drought may have brought down Angkor Wat

Historians have long debated the cause of the collapse of the ancient city of Angkor in Cambodia. Now, through the study of tree rings, they believe that the city was brought low by a massive drought.

The Angkorian kings were best known for their construction of marvelous temples including Angkor Wat. Experts feel that the drought, from 1415 until 1439, may have caused the deforestation of the area, making attack by the Siamese easier.
