War is an important phenomenon reflecting on Peyami Safa’s novels. Having witnessed the transition from the Empire to nation-state, and Second World War later, Safa could not alienate himself and his novel characters from these processes. Hence, the study first dwells on how the concept of war was defined by Peyami Safa, and what kinds of meanings were attributed to this concept. Then, the longing for the previous state of the country prior to war in the works was dealt with through the heroes. The reasons transforming this longing into frustration through the end of the war are mainly traced in the sections where Safa’s own opinions are expressed. Theoretical analyses regarding the war ends with the analyses on the poverty and degeneration, which are the results of the war. Peyami Safa also fictionalized shooting-war scenes to support theoretical analyses. In the study, these are analyzed under the categories of people at the fronts, situations at the front, and the subject of the war at the other side referring to behaviors of the opponent soldiers. It is believed that Peyami Safa’s efforts to keep these scenes vivid and current validity of his theoretical analyses are the reasons keeping him on the agenda even today.
