It is significant that the first historiographical work, Herodotus' Histories, arose in the aftermath of a military confrontation such as the Medical Wars. There were other mechanisms in antiquity for recording the events of war and keeping them alive in memory. From the power narratives of the ancient Near East, long before Homer, this function was already present in the conception of the story of the past. In the Greek world, epic poetry aimed to represent the past in an uncontested way, which was the past of war conflicts, to the glory of the ruling aristocracy, and in democratic Athens, Aeschylus' tragedy The Persians brought the plight of the victims of war to the stage. But the emergence of the historiographical genre, as a result of a recent conflict, highlighted the close relationship that would henceforth exist between war and historiography. This relationship has usually been fossilised in the more traditional formula of political history, and we probably cannot speak of other trends in relation to historiographical production until the twentieth century, curiously enough a time of global and stark conflict worldwide. Our interest as researchers starts from the history of antiquity to try to understand the trends and explanations of historians, ancient and modern.
