Thai nationalism is a political ideology involving the application of nationalism to the political discourse of Thailand. It was first popularised by King Vajiravudh, and was subsequently adopted and adapted by various leading political factions throughout the twentieth century.
The flag of Thailand is commonly invoked as a nationalist symbol.
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.
