> Angkor was a megacity supporting at least 0.1% of the global population during 1010-1220... The Angkorian period began in AD 802, when the Khmer Hindu monarch Jayavarman II declared himself a “universal monarch” and “god-king”, and lasted until the late 14th century, first falling under Ayutthayan suzerainty in 1351. A Khmer rebellion resulted in the 1431 sacking of Angkor by Ayutthaya, causing its population to migrate south to Longvek.
