Zoroastrianism
The religion of ancient Iran founded on Zarathustra's teaching — ethical dualism between truth (asha) and the lie (druj), final judgment, and history with a destination. A documented Persian-period contact with Second Temple Judaism makes it a likely bridge to later angelology, eschatology, and messianic expectation, a scholarly influence-debate stated without adjudication. Survives today in the Parsi and Iranian Zoroastrian communities.
