Lost Generation

The Lost Generation was the demographic cohort that reached early adulthood in the decade before, or during, World War I, and preceded the Greatest Generation. This generation is generally defined as people born from 1883 to 1900. They came of age in either the 1900s or the 1910s, and were the first generation to mature in the 20th century. The term is also particularly used to refer to a group of American expatriate writers living in Paris during the 1920s. Gertrude Stein is credited with coining the term, and it was subsequently popularized by Ernest Hemingway, who used it in the epigraph for his 1926 novel The Sun Also Rises: "You are all a lost generation." "Lost" in this context refers to the "disoriented, wandering, directionless" spirit of many of the war's survivors in the early interwar period.

In the wake of the Industrial Revolution, Western members of the Lost Generation grew up in societies that were more literate, consumerist, and media-saturated than ever before, but which also tended to maintain strictly conservative social values. Young men of the cohort were mobilized on a mass scale for World War I, a conflict that was often seen as the defining moment of their age group's lifespan. Young women also contributed to and were affected by the war, and in its aftermath gained greater freedoms politically and in other areas of life. The Lost Generation was also heavily vulnerable to the Spanish flu pandemic, and became the driving force behind many cultural changes, particularly in major cities during what became known as the Roaring Twenties.
