According to a recent study published in the Proceedings of the National Academy of Sciences (PNAS), the city of Angkor underwent a gradual decline in occupation rather than an abrupt collapse. The study has pointed out that Angkor demise was not caused by the Ayutthayan (Siamese kingdom located in present day-Thailand) invasion or by infrastructural failure, but a gradual demographic shift by the urban elite
Angkor is located in Cambodia’s northern province of Siem Reap. It was the capital of the Khmer Kingdom. The Khmer empire was a powerful state in South East Asia, lasting from 802 CE to 1431 CE. It was a Hindu-Buddhist empire.
Two important monuments in Angkor are a) Angkor Wat, a temple complex built by King Suryavarman II and b) Angkor Thom, a temple complex built by King Jayavarman VII. Angkor is an UNESCO World Heritage Site.
