The Lost Generation refers to a group of American writers who came of age during World War I and established their literary reputations in the 1920s. This term was coined by Gertrude Stein and popularized by Ernest Hemingway in his novel "The Sun Also Rises." This period was marked by feelings of disillusionment and loss, a response to the horrors of war and the rapid changes it brought to society. Writers like Hemingway, F. Scott Fitzgerald, Ezra Pound, and T.S. Eliot are associated with this era, and their works often reflect a sense of aimlessness and despair. These authors didn't shy away from exploring the darker sides of human nature. For instance, Fitzgerald’s "The Great Gatsby" painted a vivid picture of the Roaring Twenties, exploring themes of decadence, idealism, resistance to change, and social upheaval. Similarly, Hemingway's "A Farewell to Arms," set against the backdrop of World War I, narrates a tragic love story, exploring themes of love and war, the nature of heroism, and the illusion of progress. These works, full of rich metaphors and complex characters, continue to resonate with readers, offering a window into a tumultuous period in American and world history. Their study provides valuable insights into the human condition and the societal transformations of the time.
