Ayutthaya, about 89 km north of Bangkok in Thailand, was the historical capital of Siam. Ramathibodi I, also known as King U Thong, is said to have founded the town around AD 1350 on an island formed by the confluence of the Chao Phraya, Lop Buri, and Pa Sak rivers. Thailand's modern state may be traced back to the creation of Ayutthaya, whose numerous rulers increased their powers to make their realm one of the most powerful in Southeast Asia.
