to all these three institutions. King Vajiravudh also took refuge in an irrational and contradictory anti-Sinicism. As a result of the mass immigration, in contrast to previous immigration waves from China, women and entire families had also come into the country, which meant that the Chinese were less assimilated and retained their cultural independence. In an article published by King Vajiravudh under a pseudonym, he described the Chinese minority as Jews of the East. King Vajiravudh also created some new social associations, for example, the Wild Tiger Corps (1911), a kind of Scout movement. In 1912, a Palace revolt, plotted by young military officers, tried unsuccessfully to overthrow and replace the king. Their goals were to change the system of government, overthrowing the ancien régime and replacing it with a modern, Westernised constitutional system, and perhaps to replace Rama VI with a prince more sympathetic to their beliefs., but the king went against the conspirators, and sentenced many of them to long prison sentences. The members of the conspiracy consisted of military and the navy, the status of the monarchy, had become challenged. World War I In 1917 Siam declared war on German Empire and Austria-Hungary, mainly to gain favour with the British and the French. Siam's token participation in World War I secured it a seat at the Versailles Peace Conference, and Foreign Minister Devawongse used this opportunity to argue for the repeal of the 19th-century unequal treaties and the restoration of full Siamese sovereignty. The United States obliged in 1920, while France and Britain followed in 1925. This victory gained the king some popularity, but it was soon undercut by discontent over other issues, such as his extravagance, which became more noticeable when a sharp postwar recession hit Siam in 1919. There was also the fact that the king had no son. He obviously preferred the company of men to women (a matter which of itself did not much concern Siamese opinion, but which did undermine the stability of the monarchy due to the absence of heirs). Thus when Rama VI died suddenly in 1925, aged only 44, the monarchy was already in a weakened state. He was succeeded by his younger brother Prajadhipok. By 1925–1926, Siamese extraterritorial rights were restored a period of five years thereafter.
