Abstract
In order to discuss the relations between history and theory on Aristotle, this paper analyses the internal structure of an Aristotle’s work, The Athenian Constitution, and tries to evaluate – in this same work (but also with regard to Aristotle’s Politics) – which kind of bonds between history and theory turn out to be seen if one speculates the formation of the theory based on political facts and, conversely, the arrangement of the facts based on political theorizing. This frame enables the author to conclude that Aristotle formulates his political theory taking into account historical evidences and that he incorporates them in his considerations on the natural and social evolution of the Polis
