The tales of the first faith.
Zoroastrianism /ˌzɒroʊˈæstriənɪzəm/, /-ˌzɔr/, also called Zarathustraism, Mazdaism and Magianism, is an ancient semi-dualistic monotheist religion of Greater Iran. Much like the Roman religion for Rome, it was adopted in differing forms as the generally inclusive overarching state religion of the Achaemenid Empire and subsequent Parthian and Sasanian empires, lending it immense prestige in ancient times. As a result, some of its leading characteristics were inherited by later religious systems, including Second Temple Judaism, Gnosticism, Christianity and Islam. It was gradually marginalized by Islam from the 7th century onwards with the decline of the Sassanid Empire. Recent estimates place the current number of Zoroastrians at around 2.6 million.
The religious philosophy of Zoroaster divided the early Iranian gods. The most important texts of the religion are those of theAvesta. In Zoroastrianism, the multifacted creator Ahura Mazda, through the Spenta Mainyu (Good Spirit) is an all-good "father" of Asha (Truth, “order, justice,") in opposition to Druj (“falsehood, deceit”) and no evil originates from it. He and his works are evident to humanity through the six primary Amesha Spentas and the host of other Yazatas, through whom worship of Mazda is ultimately directed. The forces of Spenta Mainyu adjoined unto "truth" oppose the Spirit's opposite,Angra Mainyu and it's forces born of Akəm Manah (“evil thinking”). Zoroastrianism has no major theological divisions, but it is not uniform. Modern-era influences have a significant impact on individual and local beliefs, practices, values and vocabulary, sometimes merging with tradition and in other cases displacing it.
