Siamese Revolution of 1932

Date: June 24, 1932 • Location: Rome, Italy

This milestone marked the outbreak and beginning of this historic period, which spanned 1932–1932.

A group of military officers and civilians engineered a bloodless coup in Siam, ending the absolute rule of the Chakri dynasty.

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.
