The Jazz Age, a term coined by F. Scott Fitzgerald, refers to the 1920s in America—a decade marked by prosperity, cultural shifts, and a pervasive sense of disillusionment among the 'Lost Generation.' Following the trauma of World War I, many young people rejected the traditional moral values of their parents' generation, instead embracing a life of hedonism and excitement. This was reflected in the popular music of the time, jazz, which broke with classical traditions through its syncopated rhythms and emphasis on improvisation. In literature, Fitzgerald's masterpiece, 'The Great Gatsby,' captured the allure and the hollow nature of the American Dream during this era. The novel explores themes of social class, wealth, and the obsession with the past, ultimately portraying the 1920s as a time of moral decay despite its superficial glamour. Other writers of the Lost Generation, like Ernest Hemingway, adopted a more sparse and direct prose style to reflect the emotional numbness felt by those who had survived the war. Together, these authors created a portrait of a society that was rapidly modernizing yet deeply unsettled by the changes it was experiencing.
