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. In the aftermath Siam had a seat at the Paris Peace Conference, and gained freedom of taxation and the revocation of extraterritoriality.
