This is an engaging, real-life portrait of one of the great Asian rulers of the nineteenth century, who set the course that preserved his country's independence and enabled it to remain the only country in Southeast Asia never to fall under European domination. It is not a conventional biography of King Mongkut or a history of his reign; rather, the author sketches the man in his many facets, furnishing a factual outline, but applying the color from the King's own writings—through which his personality and character shine so clearly—and from other contemporary sources. Many of these appear in English for the first time.

As ruler and diplomat, as philosopher and scientist, as monk and head of a large family, Mongkut showed powers of mind and spirit extraordinary in any age. As here presented, he is even more remarkable than the caricature of him depicted in some recent popular accounts.
