"The Great Gatsby" was written in the time period of the 1920s. F. Scott Fitzgerald experienced this era firsthand and wrote his classic novel about the excess of the era.
Known as the Roaring '20s and the Jazz Age in the United States, this decade was one of the loudest, rowdiest times in the nation's history until that point. Prohibition was in effect, which led to those with greater wealth to throw extravagant parties at which alcohol and excess flowed freely. Fitzgerald's main character in the book, Jay Gatsby, embodied the attitude and spirit of the time with his raucous affairs and wild soirées.
