1933 Siamese coup d'état  The Siamese coup d’état of June 1933 () was considered the first time in Thai history that the military successfully overthrew the constitutional government. The coup took place peacefully on 20 June 1933 in Bangkok. The coup was led by Colonel Phraya Phahol Pholphayuhasena against the premiership of the Premier Phraya Manopakorn Nititada. The coup was in effect a counter-coup against the dictatorial policies of Phraya Mano stemming from the "Yellow cover dossier crisis." On 24 June 1932, the Khana Ratsadon ('People's Party') carried out a peaceful revolution against the rule of King Prajadhipok (Rama VII) the absolute monarch of Siam. The party forced the King to give up his absolute powers and gave the Siamese people their first written constitution. On 10 December 1932, a "permanent" charter was promulgated with the blessings of the new constitutional monarch. The constitution stripped the king of most of his powers, to be exercised instead by the new Government of Siam, which included the People's Assembly () (the legislature), the People's Committee (), (the executive), and the Supreme Court, (the judiciary) (). The president of this new assemblage would be the head of government and in de facto Prime Minister of Siam. The role was offered and accepted by the 48 year-old former Minister of Justice, Privy Councillor and Middle Temple lawyer Phraya Manopakorn Nititada. His title was later changed to prime minister as the old title was deemed too communistic. Phraya Mano was considered at the time the least controversial choice for the post of prime minister due to his lack of conflict, his neutrality, and whose hands were deemed the "cleanest". The new People's Committee (the government) was made up of 20 ministers of state, 10 of whom came from the People's Party while the 10 others, high ranking civil servants, were picked by the party. The committee quickly turned dictatorial. On 15 March 1933 Pridi Phanomyong, one of the founding members of the People's Party, a revolutionary, and member of the People's Committee and minister of state submitted to the People's Assembly a "Draft National Economic Plan", the so-called "Yellow Cover Dossier" (). The dossier outlined Pridi's plan for the country including an overhaul of the county's economic, financial, and social structure.
