The Siamese revolution of 1932 or Siamese coup d'état of 1932 was a coup d'état by Khana Ratsadon which occurred in Siam on 24 June 1932. It ended Siam's centuries-long absolute monarchy rule under the Chakri dynasty and resulted in a bloodless transition of Siam into a constitutional monarchy, the introduction of democracy and the first constitution, and the creation of the National Assembly. Dissatisfaction caused by the economic crisis, the lack of a competent government, and the rise of Western-educated commoners fueled the revolution.
