Oklahoma! is the first musical written by the duo of Rodgers and Hammerstein. The musical is based on Lynn Riggs's 1931 play, Green Grow the Lilacs. Set in farm country outside the town of Claremore, Indian Territory, in 1906, it tells the story of farm girl Laurey Williams and her courtship by two rival suitors, cowboy Curly McLain and the sinister and frightening farmhand Jud Fry. A secondary romance concerns cowboy Will Parker and his flirtatious fiancée, Ado Annie.
