Originally founded by King U-Thong in 1350 within a bend of the Chao Phraya river, Ayutthaya was the capital of the Thai kingdom at its mightiest. Conquered and sacked by the Burmese in 1767, today only the ruins of its splendor remain. The modern city was founded a few kilometers further east.
Ayutthaya was named after the ancient Indian city of Ayodhya, and is sometimes referred to by that name. Among Thai cities, Ayutthaya's English name is probably the least standardized - it is also known as Ayotaya, Ayothaya, Ayudhya, Ayutaya, Ayuthaya and Ayuttaya.
