World War I literature captures the brutal reality of trench warfare and its psychological toll on soldiers and civilians. Authors like Remarque, Hemingway, Owen, and Sassoon use vivid imagery and irony to challenge glorified notions of war and expose the futility of conflict. These works explore themes of lost innocence, disillusionment, and the human cost of war. They reflect the profound impact of new technologies on warfare and society, while also highlighting the changing roles of women and the search for meaning in a world forever altered by global conflict.
