Ayutthaya

Ayutthaya was a Thai kingdom centered in the Chao Phraya River valley. In 1337, the kingdom did not yet exist; it was founded in 1351.

It became a Burmese Toungoo vassal in 1569 but regained independence in 1584. Under King Narai, its merchants traded widely and an embassy visited the French court of Louis XIV in 1686. Konbaung Burmese armies invaded from the north and west in 1765; after a fourteen-month siege they captured and destroyed Ayutthaya in 1767, ending the kingdom.
