Zoroastrianism (Magianism) is a religion based on ancient Indo-Iranian Aryan religions (2,000-500 BC) and the prophet Zoroaster (Zarathustra 600 BC). The term ‘Magi’ in the Christian Bible referred to their priests (wise men). The roots of Zoroastrianism are dualist, based on two equally powerful forces of Good and Evil (like Yen-Yang). After the teachings of Zarathustra, the religion becomes more monotheistic; with an emphasis on Good (Ahura Mazda). Eventually Evil (Ahriman Shaitan) was demoted to the level of the chief immortal evil spirit power that is not called a god by the main priests and scriptures, but has the powers of a secondary god (Druj – like Satan). – (Gathas scriptures)
Zoroaster promoted the status of Ahura Mazda, while demoting all other deities and rejecting past rituals. Pre-Islamic Iranian dynasties gave Zoroastrianism immense prestige in ancient times, and some of its leading doctrines were adopted by other religious systems. In the middle ages Islamic Arabs conquered Iran and subjugated Zoroastrianism. For some reason its earliest record in western history was in 1,643 AD (Thomas Browne).
Zoroastrian eschatology and demonology influenced the Abrahamic religions. Abrahamic religions are the monotheistic faiths sharing a common origin ancestor, Abraham. The largest Abrahamic religions are now Judaism, Christianity, Islam, and Bahaí.
