(E. Y.) The town of Lampun (Labong or Haribunchai), the first Lao capital in Siam, was founded about A.D. 575. The fusion of races may be said to have begun then, and the Siamese language, writ ten character and other racial peculiarities were in course of formation. But the finishing touches to the new race were supplied by the great expulsion of Lao-Tai from south-west China by Kublai Khan in A.D. Thereafter the north, the west and the south-west of Siam, comprising the kingdom of Swankalok-Suk hotai, and the states of Suphan and Nakhon Sri Tammarat (Ligore), with their sub-feudatories, were reduced by the Siamese (Thai), who, during their southern progress, moved their capital from Sukhotai to Nakhon Sawan, thence to Kampeng Pet, and thence again to Suvarnabhumi near the present Kanburi. A Suk hotai inscription of about 1284 states that the dominions of King Rama Kamheng extended across the country from the Mekong to Pechaburi, and thence down the Gulf of Siam to Ligore; and the Malay annals say that the Siamese had penetrated to the extremity of the peninsula before the first Malay colony from Menangkabu founded Singapore, i.e., about 116o.
Sano also was attacked, and its fall completed the ascendancy of the Siamese (Thai) throughout the country. The city of Ayuthia which rose in A.D. 135o upon the ruins of Sano was the capital of the first true Siamese king of all Siam. This king's sway
extended to Moulmein, Tavoy, Tenasserim and the whole Malacca peninsula. About this time Siam attacked Cambodia, seized Angkor and carried off some 90,00o prisoners. This was the begin ning of a series of wars lasting some 400 years, until Cambodia fell entirely under Siamese rule and influence. Vigorous attacks were also made during this period on the Lao states to the north-west and north-east, and Siamese supremacy was pretty firmly estab lished in Chiengmai and its dependencies by the end of the 18th century, and over the great eastern capitals, Luang Prabang and Vien-chang, about 1828.
The intercourse between France and Siam began about 168o under Phra Narain, who, by the advice of his minister, the Cephalonian adventurer Constantine Phaulcon, sent an embassy to Louis XIV. An interesting episode was the active intercourse, chiefly commercial, between the Siamese and Japanese govern ments from 1592 to 1632. Japan was, in 1636, closed to foreigners; but trade was carried on at all events down to 1745 through Dutch and Chinese and occasional English traders. In 1752 an embassy came from Ceylon, desiring to renew the ancient friendship and to discuss religious matters. After the fall of Ayuthia a great general, Phaya Takh Sin, collected the remains of the army and restored the fortunes of the kingdom, establishing his capital at Bangkok; but, becoming insane, he was put to death, and was succeeded by another successful general, Phaya Chakkri, who founded the present dynasty. Under him Tenasserim was invaded and Tavoy held for the last time by the Siamese in 1792, though in 1825, taking advantage of the Burmese difficulty with England, they bombarded some of the towns on that coast. The supremacy of China is indicated by occasional missions sent, as on the found ing of a new dynasty, to Peking, to bring back a seal and a calendar.
