The King and I was a musical by Rodgers and Hammerstein based on Margaret Landon‘s novel, Anna and the King of Siam derived from the memoirs of a governess to the children of King Mongkut of Siam in the early 1860s.

In the musical, a British schoolteacher named Anna is hired to assist the King’s drive to modernize his country. Although there is conflict between the King and Anna, there is as well a love neither can admit.

The musical premiered in March 1951, at Broadway’s St. James Theatre and ran for nearly three years and has had many revivals.
