This article presents a detailed exploration on the profound transformation set to work on the concept of 'history' by Martin Heidegger's risky leap from metaphysics into the domain of thinking (the thinking of Being). At first, the exposition follows closely the inner logic of metaphysical thinking in order to prove then the necessarily metaphysical position held by its two ways of processing history: the philosophy of history and historiography. From this point, the article moves further on to consider a radically new way of grasping the nature of history: that which Heidegger calls "the other beginning".
