This book examines two aspects of the abbreviated reign of King Ananda Mahidol (1935-1946), or King Rama VIII, of the current Chakri dynasty of Thailand. First, it discusses the royal family’s plot to thwart a romantic relationship between the young king, Ananda, and his Swiss girlfriend, Marileine Ferrari, a daughter of a famous pastor of Lausanne, Switzerland. Interracial marriage, particularly with Westerners, has been strictly forbidden for Thai kings or heirs apparent. The restriction stems from the interwoven connection between sexual relationship and the security of the throne. The second part investigates the mysterious death of King Ananda, a long-held taboo topic in Thailand. Although the two events were not specially related, both in their own way served to unavoidably shake the position of the monarchy and hence threaten its existence. The palace’s reactions to these events demonstrated its continuous search to maintain its power and ultimately to warrant its survival.
