Anna and the King is a 1944 semi-fictionalized biographical novel by Margaret Landon. In the early 1860s, Anna Leonowens, a widow with two young children, was invited to Siam (now Thailand) by King Mongkut (Rama IV), who wanted her to teach his children and wives the English language and introduce them to British customs. Her experiences during the five years she spent in the country served as the basis for two memoirs, The English Governess at the Siamese Court (1870) and Romance of the Harem (1872).
