context_page_description: The Constitution of the Kingdom of Thailand provides the basis for the rule of law in Thailand.
context_section_description: At the end of the World War II, the collaborationist leadership (including Marshal Plaek) was arrested and tried for war crimes, democratic elections for the entire People's Assembly were first held, and the young King Ananda Mahidol returned to Thailand for the first time in seven years. King Ananda Mahidol had just come of age, turning 20 in September 1945, and returned with his mother and Prince Bhumibol in December 1945.
  A new constitution, Thailand's most democratic until the enactment of the 1997 People's constitution, was drafted in his honor. In 1972, Pridi Banomyong called it the constitution that gave the Thai people the most complete democratic rights, though these guarantees were later surpassed by those of the 1997 and 2007 constitutions. One key difference from previous constitutions was that the House of Representatives would, for the first time, be fully elected by the people (176 members). A Senate (80 members) was also established, which would, unlike the British House of Lords, be elected by the House for six-year terms. In addition, active civil servants and soldiers were banned from serving in the parliament or cabinet, thus reducing the power of the military.  A ban on senior princes participating in electoral politics was repealed, thus precluding only the king and four other people from politics.
  The constitution was promulgated on 9 May 1946. One month later, on 9 June 1946, the king was found shot to death. His death was soon followed by a military uprising on 8 November 1947 that abrogated the 1946 constitution.
