802 AD Angkor Period-

he Khmer Empire (Khmer: ចក្រភពខ្មែរ), the predecessor state to modern Cambodia ("Kampuchea" or "Srok Khmer" to theKhmer people), was a powerful Khmer Hindu-Buddhist empire in Southeast Asia. The empire, which grew out of the former kingdoms of Funan and Chenla, at times ruled over and/or vassalised most of mainland Southeast Asia, parts of modern-dayLaos, Thailand, and southern Vietnam.^[1]

Its greatest legacy is Angkor, in present-day Cambodia, which was the site of the capital city during the empire's zenith. The majestic monuments of Angkor – such as Angkor Wat and Bayon – bear testimony to the Khmer Empire's immense power and wealth, impressive art and culture, architectural technique and aesthetics achievements, as well as the variety of belief systems that it patronised over time. Satellite imaging has revealed that Angkor, during it peak in the 11th to 13th centuries, was the largest pre-industrial urban centre in the world.^[2]

The beginning of the era of the Khmer Empire is conventionally dated to 802 AD. In this year, King Jayavarman II had himself declared chakravartin ("king of the world", or "king of kings") on Phnom Kulen. The empire ended with the fall of Angkor in the 15th century.
