War is the collision of two or more states after diplomatic relations are cut off and special methods and tools are used through their armies. Wars often occur with the intention of using force that the two enemies cannot obtain in another way. For example, the Cold War period in military definition is society’s exposure to financial and emotional effects. These impacts are recorded in the works of art that were created during and after the war years. Literature includes all cultural artifacts based on a nation’s language, whether it has been transcribed or not. In a narrow sense, they are language artifacts written in an artistic manner of form and content and have certain rules. It is possible to evaluate previously written articles about “War Literature” which emerged by combining two concepts with different meanings in two groups. On one hand, according to writers in the first group, there is war literature and it is really important. On the other hand, those in the other group, who mostly take into consideration 20th century wars, argue that wars based on economic interests do not influence art and literature. However, art and thought actually make progress in times of peace. Extreme sentimentality, which had been substituted for logic in years of war, accelerates the shift of artwork toward conservatism, so peace is a great blessing compared to war. During war years, the human psyche was full of romantic, epic, and divine heroism. Yet the intellectuals were not sufficiently aware of the psychology of soldiers until the World War I. However, this psychology appeared in literary works of that period and was kept alive in romantic scenes. A common view in the articles is that the wars that were considered romantic in ancient times have influenced literature. The most important aspect of the wars during these times was the quality of individual courage and physical superiority. Men gaining a place in society depends on the heroism they show in wars, and that heroism has been superhumanly embroidered in the epics of the age's literary artifacts. Indeed, it is for this reason that these epics, which include epic characters, have been told many times for the name of a hero. The same situation continued in the Middle Ages by taking on a religious character. These wars, which were shaped in the imagination of both the artist and the people exposed to the pains of war, found a new life in literary works, especially in literary works containing an aesthetic purpose and were written directly to create war literature. This literature, which is clearly seen in poetry, novels, stories, and dramas, finds popularity in times of war. With the development of the press in the last century, public interest in wars has increased and the community has had the opportunity to follow circumstances in terms of the politics, military, history, as well as the literature. From the moment they appeared in the scene of history, Turks living inside wars have a rooted war literature. However, these literary sources have not been studied extensively and brought to light. In this work, Turkish war literature was examined from a comprehensive perspective and studied with sources, periods, texts, poets, and writers, and the importance of these works has been revealed in terms of national spirit and unity.
