The new government was headed by Khuang Aphaiwong, a civilian linked politically with conservatives like Seni. The most influential figure in the regime, however, was Pridi, whose antiJapanese views were increasingly attractive to the Thai. In the last year of the war, Allied agents were tacitly given free access by Bangkok. As the war came to an end, Thailand repudiated its wartime agreements with Japan.
The civilian leaders, however, were unable to achieve unity. After a falling-out with Pridi, Khuang was replaced as prime minister by the regent’s nominee, Seni, who had returned to Thailand from his post in Washington. The scramble for power among factions in late 1945 created political divisions in the ranks of the civilian leaders that destroyed their potential for making a common stand against the resurgent political force of the military in the postwar years.
Postwar accommodations with the Allies also weakened the civilian government. As a result of the contributions made to the Allied war efforts by the Free Thai Movement, the United States, which unlike the other Allies had never officially been at war with Thailand, refrained from dealing with Thailand as an enemy country in postwar peace negotiations. Before signing a peace treaty, however, Britain demanded war reparations in the form of rice for shipment to Malaya, and France refused to permit admission of Thailand to the United Nations (UN) until Indochinese territories annexed during the war were returned. The Soviet Union insisted on the repeal of anticommunist legislation.
The government set up an agency to manage the delivery of rice as part of Thai war reparations. These reparations were initially to total 1.5 million tons, or approximately 10 percent of the annual yield, but the figure was adjusted downward, and the reparations were paid off within two years. However, the government retained the policy of regulating the rice trade as an income-producing device.
The Seni government survived only until the peace treaty with Britain was signed in January 1946. Public discontent grew--the result of inflation, the reparation payments to the British, the surrender of territorial gains that many Thai considered to have been legitimate, and mismanagement at every level of government. Pridi restored Khuang to office for a time but in March 1946 was obliged to assume the prime ministership himself in an effort to restore confidence in the civilian regime.
Pridi, who argued that the strength of any civilian regime depended on a functioning parliament, worked with his cabinet to draft a new constitution that established parliamentary structures. The constitution, promulgated in May 1946, called for a bicameral legislature. The lower house the House of Representatives, was elected by popular vote; the upper house, the Senate, was elected by the lower house. This constitution was tailor made for Pridi’s purposes, ensuring him a parliamentary majority that would support his programs.
The 1946 election, which had in fact preceded enactment of the constitution, was the first in which political parties participated. Two coalition parties--Pridi’s own party, the Constitutional Front, and the Cooperation Party--won a large majority of seats in the lower house and, in turn, sent a proPridi majority to the upper house. Parliamentary opposition was led by the Democrat (Prachathipat) Party, headed by Seni and Khuang.
Pridi’s prestige suffered permanent damage two weeks after the election of the upper house, however, when Ananda Mahidol, who had returned from Switzerland a few months earlier, was found dead in his bed at the palace, a bullet wound through his head. Although the official account attributed the king’s death to an accident, there was widespread doubt because few facts were made public. Rumors implicated Pridi. Two months later, in August, Pridi resigned on grounds of ill health and went abroad, leaving Luang Thamrongnawasawat as prime minister.
The late king’s younger brother, nineteen-year-old Bhumibol Adulyadej (Rama IX, 1946- ), was chosen as successor to the throne. The new king had been born in the United States, had spent his childhood in Switzerland, and had gone to Thailand for the first time in 1945 with his brother. He returned to Switzerland to complete his schooling and did not return to Bangkok to take up his duties until 1951.
