Zoroastrianism is a religion and philosophy based on the teachings of prophet Zoroaster (also known as Zarathustra, in Avestan), probably founded some time before the 6th century BC in Iran. The term Zoroastrianism is, in general usage, essentially synonymous with Mazdaism, i.e., the worship of Ahura Mazda, exalted by Zoroaster as the supreme divine authority.
In Zoroastrianism, the Creator Ahura Mazda is all good, and no evil originates from Him. Thus, in Zoroastrianism good and evil have distinct sources, with evil (druj) trying to destroy the creation of Mazda (asha), and good trying to sustain it. Mazda is not immanent in the world, and His creation is represented by the Amesha Spentas and the host of other Yazatas, through whom the works of God are evident to humanity, and through whom worship of Mazda is ultimately directed. The most important texts of the religion are those of the Avesta, of which a significant portion has been lost, and mostly only the liturgies of which have survived. The lost portions are known of only through references and brief quotations in the later works of (primarily) the 9th-11th centuries.
Zoroastrianism is of great antiquity.[1] In some form, it served as the national- or state religion of a significant portion of the Iranian people for many centuries before it was gradually marginalized by Islam from the 7th century onwards. The political power of the pre-Islamic Iranian dynasties lent Zoroastrianism immense prestige in ancient times, and some of its leading doctrines were adopted by other religious systems. It has no major theological divisions (the only significant schism is based on calendar differences), but it is not monolithic. Modern-era influences have a significant impact on individual/local beliefs, practices, values and vocabulary, sometimes complementing tradition and enriching it, but sometimes also displacing tradition entirely.
