Henri Barbusse began his literary career in the 1890s as a Symbolist poet before transitioning into a neo-Naturalist novelist. Despite his pre-war pacifist beliefs, he volunteered for military service in 1914 during World War I, earning the Croix de guerre. His firsthand experiences in the trenches inspired his landmark 1916 novel, Under Fire, which is widely recognized as one of the earliest and most influential works of the Lost Generation movement, deeply impacting subsequent writers such as Ernest Hemingway and Erich Maria Remarque.
During the war, Barbusse's political views shifted toward communism. He came to believe that a revolution against imperialist governments was the only viable path to ending the conflict and dismantling militarism. In the post-war years, his writing took on a distinct political edge. He joined the French Communist Party and became a prominent anti-fascist and anti-war activist, blending his wartime memories with moral and political meditations.
In the 1930s, Barbusse became an ardent supporter of the Stalinist regime, despite having maintained a friendly relationship with Leon Trotsky in the mid-1920s. He contributed to the personality cult of Joseph Stalin by writing a biography of the Soviet leader, which became a key text for French Stalinists. Barbusse, who was also a lifelong friend of Albert Einstein, died in 1935, prior to the Moscow trials and the Nazi-Soviet pact.
