Zoroastrianism offers a remarkable presentation of the origin of humankind, its present condition, and its final destiny. Human history is considered to be the result of a cosmological strategy enacted by god himself, Ohrmazd, in order to compel his direct and primordial antagonist, the evil Ahreman, to engage battle in our world. Eventually, the forces of darkness will be completely destroyed at the conclusion of a chiliadic temporal cycle. The most important battle in order to defeat Ahreman is fought by humankind. The importance of history in this teleology accounts for the emphasis put by it on the political dimension. We evoke the Sasanian period, in which the Persian kings assumed the status of a kosmokrátor, i.e. of a universal king, charged with achieving victory over evil. We offer in this article an overview of the intellectual contribution of the Pre-Islamic Iranian world to the idea of history.
