Zoroastrianism

Zoroastrianism is an Iranian religion based on the teachings of the prophet Zarathustra, also known as Zoroaster, as set forth in the primary religious text called the Avesta. It exalts a supreme benevolent deity, Ahura Mazda, and opposes him with a destructive spirit, Angra Mainyu, in a dualistic cosmology that predicts the ultimate triumph of good over evil. The religion has a complex classification, with varying opinions among scholars as to whether it is monotheistic, polytheistic, or henotheistic, and has had significant influence on Iranian culture and history.learn more on wikipedia
