The Khana Ratsadon staged a coup d'état 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 economic crisis and incompetent government, as well as the rise of Western-educated non-royals to positions of influence, fueled the revolution.

King Prajadhipok remained on the throne and compromised with Khana Ratsadon. Two coups were mounted during the following year, in April and June, amid infighting within the government over Pridi Banomyong's socialist planned economy and a rebellion of royalists.
