Ayutthaya Kingdom
Also known as Ayutthaya
Ayutthaya was founded in 1351 by King U Thong, who took the title Ramathibodi I, on an island where three rivers meet in Thailand's central plain. The kingdom absorbed the older Thai state of Sukhothai and in 1431 sacked Angkor, inheriting Khmer ideas of divine kingship.
Its rulers built a highly organised state, with the sakdina system ranking every subject by land and duty. Ayutthaya became one of Asia's great trading cities, home to Chinese, Persian, Japanese, Portuguese, Dutch and French merchants, and King Narai exchanged embassies with Louis XIV. For centuries it fought Burmese kingdoms; it fell to Burma in 1569, until King Naresuan restored its independence. In 1767 a Burmese army destroyed the city after a long siege, ending the kingdom.
