With the death of Taksin, the Thai throne fell to Chakkri, a general who had played a leading role with Taksin in the struggle against the Burmese. As King Yot Fa (Rama I, 1782-1809), he founded the present Thai ruling house and moved the court to Bangkok, the modern capital (see thailand/th_appen.asp#table2"> table 2, Appendix). During an energetic reign, he revived the country’s economy and restored what remained of the great artistic heritage lost in the destruction of Ayutthaya. The king is credited with composing a new edition of the Ramakian (the Thai version of the Ramayana) to replace manuscripts of the Thai national epic that were lost in the conflagration.
In the following years Thai influence grew until challenged by Western powers. In 1795 the Thai seized the provinces of Battambang and Siem Reap in Cambodia, where throughout the first half of the next century Chakkri kings would resist Vietnamese incursions. The conflict between the Thai and the Vietnamese was resolved finally by a compromise providing for the establishment of a joint protectorate over Cambodia. The Thai also pressed their claim to suzerainty in the Malay state of Kedah in the face of growing British interest in the peninsula. As a result of the Anglo-Burmese War (1824-26), Britain annexed territory in the region that had been contested by the Thai and the Burmese for centuries. This move led to the signing of the Burney Treaty in 1826, an Anglo-Thai agreement that allowed British merchants modest trade concessions in the kingdom. In 1833 the Thai reached a similar understanding with the United States.
Chakkri expansionism had been halted in all directions by the end of the reign of Nang Klao (Rama III, 1824-51) as tributary provinces began to slip away from Bangkok’s control and Western influence grew. In 1850 Nang Klao spurned British and American requests for more generous trading privileges similar to those that Western powers had exacted by force from China. Succeeding Thai monarchs, however, were less successful in controlling Western economic influence in their country.
The first three Chakkri kings, by succeeding each other without bloodshed, had brought the kingdom a degree of political stability that had been lacking in the Ayutthaya period. There was, however, no rule providing for automatic succession to the throne. If there was no uparaja at the time of the king’s death--and this was frequently the case--the choice of a new monarch drawn from the royal family was left to the Senabodi, the council of senior officials, princes, and Buddhist prelates that assembled at the death of a king. It was such a council that chose Nang Klao’s successor.
