Oscar Hammerstein's commitment to idealizing and encouraging tolerance theatrically started with his libretto to "Show Boat". It can be seen in his later works, many of which were set to music by Richard Rodgers. "Carmen Jones" is an attempt to present a modern version of the classic French opera through the experiences of African Americans during wartime, and "South Pacific" explores interracial marriage and prejudice. Finally, "The King and I" deals with different cultures' preconceived notions regarding each other and the possibility for cultural inclusiveness in societies.
