Ayutthaya Period 1350 - 1767 A.D. (1893-2310 B.E.)
The Kingdom of Ayutthaya was founded by U-Thong, an adventurer who is said to have descended from a wealthy Chinese merchant family who married into royalty. In 1350 A.D. to escape the threat of an epidemic he moved his court south into the rich flood plain of the Chao Phraya River. On an island he found a new capital which he called Ayutthaya after the city of Ayodhya in Northern India. U-Thong Assumed the royal name of King Ramathibodi.
Ramathibodi (1350-60 A.D.) applied political skill and relations shrewdly to fill the power vacuum in Central Thailand following the decline of Sukhothai and the waning reach of Angkor. Appointing his son on the Throne of Lopburi and founding his new Kingdom along the Chao Phraya river, Ramathibodi I, the first king of Ayutthaya, established a powerful kingdom that may even have sacked Angkor. He organized the administration into four powers under Grand Ministers; State, the Royal Household, Treasury, and Agriculture. This administration form was used through over 400 years of the Ayutthaya period. About 80yrs after Ayutthaya was established , the Khemer Empire fell to Ayutthaya and it’s capital was moved from Angkor to Pvek and Phenom Penh with large numbers of Khemer POWs brought along to Ayutthaya. By the end of the 14th century Ayutthaya was regarded as the strongest power in South East Asia, however it lacked the military to dominate the region.
After a bloody dynastic struggle in the 1690’s Ayutthaya entered into a golden age, a relatively peaceful period in the second quarter of the 18th century when art, literature, and learning flourished. During the 17th and 18th century the Thais moved down from the north and the Vietnamese came in from the ast occupying much of present day Cambodia and pushing the Khmer into a small corner of their former empire.
