Phra Sarasas, author of My Country Thailand, a historical work critical of the Thai monarchy, claimed to have shaped the 1932 overthrow of the absolute monarchy in Siam. He became Minister of Economic Affairs briefly in 1937, and promoted the pro-Japanese cause in Thailand with sufficient enthusiasm to be accused of war crimes after the Japanese surrender, but escaped prosecution when the Thai Supreme Court ruled that the War Crimes Act was illegal. His limited political career never matched his aspirations and Phra Sarasas remained a marginal figure, but his life and work nevertheless throw an interesting light on events during this formative period of modern Thai history.
