Speaking of models in history is a delicate matter. Since its emergence at the time of World War II in the area of our academic studies, the word covers different ways of thinking the historical method and practice. A minority of historians, mostly in the field of economic history, take models as new tools establishing a link with mathematics, and especially today, with game theory. On the other hand, all of this is mostly a question of semantic change for most of them, and does not mean anything deeper. Historians create and use models basically to explain their works and to establish comparisons. In some cases though they might be taken hostage by their own models, by misusing models designed for other purpose or by using them without knowledge.
