The Palace Revolt of 1912 was a failed attempt by Western-educated military officers to overthrow the Siamese monarchy. Vajiravudh (r. 1910–1925) responded by propaganda for the entirety of his reign. He promoted the idea of the Thai nation. In 1917, Siam joined the First World War on the side of the Allies as there were concerns that the Allies might punish neutral countries and refuse to amend past unequal treaties. In the aftermath Siam joined the Paris Peace Conference, and gained freedom of taxation and the revocation of extraterritoriality.
