Thailand: Early History

Early History

Like other countries of Southeast Asia, Thailand in prehistoric times was peopled through successive migrations from central Asia into territory already inhabited by the Negrito peoples. Although a few Thai groups (ethnically related to the Shan of Myanmar and the Lao of Laos) migrated to the northern hill country of Thailand, the main body of Thais remained in Yunnan, China, where by a.d. 650 they had organized the independent kingdom of Nanchao. By 1000, however, the Chinese had overrun Nanchao and made it a tributary state. With the destruction of the kingdom of Nanchao by the Mongols under Kublai Khan in 1253, the slow infiltration of Thailand from the north turned into a mass migration. By that time the Khmer Empire was well established in the Chao Phraya valley and on the Korat plateau.

The Thais captured the Khmer town of Sukhothai, in N central Thailand, and a new Thai nation, with its capital at Sukhothai, soon developed. During this period (c.1260–1350), King Rama Kamheng, whose 40-year reign began c.1275, borrowed from the Khmers of Cambodia the alphabet that the Thais still use. He extended Sukhothai power southward to the sea and down the Malay Peninsula, and contact was made with India. After the death of Rama Kamheng, Sukhothai declined and was absorbed by Rama Tibodi, prince of Utong, who established (c.1350) a new capital at Ayutthaya. The kings of Ayutthaya consolidated their power in S Siam and the Malay Peninsula, then launched a long series of indecisive wars against the Lao state of Chiang Mai and against Cambodia, which did not end until the 19th cent. The 16th cent. saw the beginnings of warfare with the Burmese; in 1568 the Burmese captured Ayutthaya and dominated the country until c.1583, when King Naresuan (1555–1605) drove them from Siam. He captured Tanintharyi and Dawei in S Myanmar and the major port of Myeik.
