The Age of Innocence is Edith Wharton's twelfth novel, initially serialized in four parts in the Pictorial Review magazine in 1920, and later released by D. Appleton and Company as a book in New York and in London. It won the 1921 Pulitzer Prize for Fiction, making Wharton the first woman to win the prize. The story is set in upper-class New York City in the 1870s, during the so-called Gilded Age.
