The country was reduced to chaos. Provinces were proclaimed independent states under military leaders, rogue monks, and cadet members of the royal family. The Thai were saved from Burmese subjugation, however, by an opportune Chinese invasion of Burma and by the leadership of a Thai military commander, Phraya Taksin.

All that remains of the old city are some impressive ruins of the royal palace. King Taksin established a capital at Thonburi, across the Chao Phraya from the present capital, Bangkok. The ruins of the historic city of Ayutthaya and "associated historic towns" in the Ayutthaya historical park have been listed by the UNESCO as World Heritage Sites. The city of Ayutthaya was refounded near the old city, and is now capital of the Ayutthaya province.
