The novel chronicles an era that Fitzgerald himself dubbed the "Jazz Age." Following the shock and chaos of World War I, American society enjoyed unprecedented levels of prosperity during the "roaring" 1920s as the economy soared. At the same time, Prohibition, the ban on the sale and manufacture of alcohol as mandated by the Eighteenth Amendment, made millionaires out of bootleggers and led to an increase in organized crime. Although Fitzgerald, like Nick Carraway in his novel, idolized the riches and glamor of the age, he was uncomfortable with the unrestrained materialism and the lack of morality that went with it.
