September 1957 Coup

Phibun had failed to win the popular support that he had sought, and the effort cost him what remained of his standing among the military faction. As a result of the election, Phibun formed a new government in March 1957, appointing Phao as interior minister with responsibility for internal security. However, it was Sarit, whose prestige had not been at stake in the election, who as newly named armed forces commander in chief emerged as the strongest member of the ruling group. In September he openly broke with his colleagues, ordered tanks into the streets, and displaced Phibun and Phao in a bloodless coup d'etat. He suspended the constitution and dissolved parliament. The king approved Sarit's action; the royal family had opposed Phibun since the 1930s.

New elections were held in December under an interim civilian government headed by Pote Sarasin, the secretary general of SEATO. No single party won a parliamentary majority, but Sarit organized a government party, the National Socialist Party, to contain the loose coalition of parties and individuals backing his regime. Because of poor health Sarit did not attempt to form a government but turned over responsibility to his deputy in the armed forces, Thanom Kittikachorn. Intraparty wrangling over political and economic spoils plagued Thanom's government. The situation was further aggravated by the inclusion in the government party of left-wing politicians who opposed its proWestern foreign policy.

Sarit revived the motto "Nation-Religion-King" as a fighting political slogan for his regime, which he characterized as combining the paternalism of the ancient Thai state and the benevolent ideals of Buddhism. He spoke of his intention to "restore" the king, a retiring man, to active participation in national life, and he urged Bhumibol Adulyadej and his consort, Queen Sirikit, to have more contact with the Thai public, which had a strong affection for the monarchy. Royal tours were also scheduled for the king and queen to represent Thailand abroad. Sarit likewise played on the religious attachments of the people. In 1962 he centralized administration of monastic institutions under a superior patriarchate friendly to the regime, and he mobilized monks, especially in the North and Northeast, to support government programs. Critics protested that Sarit had demeaned religion by using it for political ends and had compromised the monarchy by using it to legitimize a military dictatorship. They asserted that the regime's policies, rather than restoring these institutions, had contributed to the growth of materialism and secularism and to the erosion of religious belief in the country.

In December 1963 Sarit died in office. His deputy, Thanom, peacefully succeeded to the prime ministership and pursued without major modifications the foreign and domestic policies of his predecessor. Retaining the cabinet that he inherited from Sarit, Thanom focused his efforts on seeking to maintain political stability; promoting economic development, especially in security-sensitive areas; raising the standard of living; and safeguarding the country from the communist threat at home and abroad.

A notable departure from Sarit's policies, however, was the Thanom government's decision to shorten the timetable for the country's transition from the military-dominated leadership structure to a popularly elected government. The prime minister urged the Constituent Assembly, appointed in 1959, to finish drafting a constitution as soon as practicable. The new leadership also relaxed stringent official controls on the press, an attempt that the authorities said was aimed at creating a new, relatively liberalized, political climate.

Although the leaders agreed on the desirability of establishing what they described as a more democratic political system in tune with the country's heritage, there were indications that they disagreed on the pace of the projected change. Some leading officials thought that an early resumption of political activities would broaden the base of politics and strengthen popular identification with the government, the monarchy, and Buddhism. Others argued that the restoration of party politics at a time when the country was confronted with serious internal problems was likely to aid the communists in their efforts to infiltrate civic, labor, student, and political organizations.

The constitution was finally proclaimed in June 1968, but martial law, which had been imposed in 1958, remained in effect. Party politics were legalized and resumed shortly after mid-1968, and general elections for the new National Assembly were held in February 1969. Thanom's United Thai People's Party returned 75 members to the 219-seat lower house, giving them the largest representation of the 13 parties, while the second-running Democrat Party won 57 seats.
