The kingdom of Ayutthaya was founded by U Thong, an adventurer allegedly descended from a rich Chinese merchant family who married royalty. In 1350, to escape the threat of an epidemic, he moved his court south into the rich floodplain of the Chao Phraya. On an island in the river he founded a new capital, which he called Ayutthaya, after Ayodhya in northern India, the city of the hero Rama in the Hindu epic Ramayana. U Thong assumed the royal name of Ramathibodi (1350-60).

Ramathibodi tried to unify his kingdom. In 1360 he declared Theravada Buddhism the official religion of Ayutthaya and brought members of a sangha, a Buddhist monastic community, from Ceylon to establish new religious orders and spread the faith among his subjects. He also compiled a legal code, based on the Indian Dharmashastra (a Hindu legal text) and Thai custom, which became the basis of royal legislation. Composed in Pali--an Indo-Aryan language closely related to Sanskrit and the language of the Theravada Buddhist scriptures--it had the force of divine injunction. Supplemented by royal decrees, Ramathibodi's legal code remained generally in force until the late nineteenth century.

By the end of the fourteenth century, Ayutthaya was regarded as the strongest power in Southeast Asia, but it lacked the manpower to dominate the region. In the last year of his reign, Ramathibodi had seized Angkor during what was to be the first of many successful Thai assaults on the Khmer capital. Thai policy was aimed at securing Ayutthaya's eastern frontier by preempting Vietnamese designs on Khmer territory. The weakened Khmer periodically submitted to Thai suzerainty, but efforts by Ayutthaya to maintain control over Angkor were repeatedly frustrated. Thai troops were frequently diverted to suppress rebellions in Sukhothai or to campaign against Chiang Mai, where Ayutthaya's expansion was tenaciously resisted. Eventually Ayutthaya subdued the territory that had belonged to Sukhothai, and the year after Ramathibodi died, his kingdom was recognized by the emperor of China's newly established Ming Dynasty as Sukhothai's rightful successor.

The Thai kingdom was not a single, unified state but rather a patchwork of self-governing principalities and tributary provinces owing allegiance to the king of Ayutthaya. These states were ruled by members of the royal family of Ayutthaya who had their own armies and warred among themselves. The king had to be vigilant to prevent royal princes from combining against him or allying with Ayutthaya's enemies. Whenever the succession was in dispute, princely governors gathered their forces and moved on the capital to press their claims.

During much of the fifteenth century Ayutthaya's energies were directed toward the Malay Peninsula, where the great trading port of Mal2d8 alacca contested Thai claims to sovereignty. Malacca and other Malay states south of Tambralinga had become Muslim early in the century, and thereafter Islam served as a symbol of Malay solidarity against the Thai. Although the Thai failed to make a vassal state of Malacca, Ayutthaya continued to control the lucrative trade on the isthmus, which attracted Chinese traders of specialty goods for the luxury markets of China.
