Definition:

Zoroastrianism was the religion of Persian empires from at least the time of Darius (521-486 B.C.), until the Arab Muslims defeated the Sassanids in the 7th century A.D. According to Zoroastrian scholar Mary Boyce, it is the oldest revealed credal religion and has influenced Judaism, Christianity, Islam, Gnostic faiths, and Buddhism.

The prophet of Zoroastrianism was Zoroaster, who may have lived as far back in time as 1000 B.C.


or even 1400. Zoroastrian scripture is the Avesta.

Zoroaster rejected the old Persian gods and in their place believed that a single, omniscient, omnipresent, and omnipotent god, Ahura Mazda, ruled and created the world. Ahura Mazda and his helping spirits, the ahuras, fought against the prince of evil, Ahriman or Angra Mainyu and the daevas (evil). This makes Zoroastrianism, the religion of Zoroaster, dualistic. Followers of Zoroastrianism are supposed to help Ahura Mazda by being good in order to establish paradise on earth. A savior (saoshyant) and an afterlife with judgment and resurrection, are other elements of Zoroastrianism, according to A Dictionary of Asian Mythology. Death is the work of Ahriman; the soul, of Ahura Mazda.

Zoroastrianism is still practiced, especially in India and Iran, by the Parsis.
