Persia before the mohummed slaughter

Zoroastrianism:
The ancient pre-Islamic religion of Persia that survives there in isolated areas, and more prosperously in India, where the descendants of Zoroastrian Persian immigrants are known as Parsis, or Parsees. In India the religion is called Parsiism.
Founded by the Persian prophet and reformer Zoroaster, the religion contains both monotheistic and dualistic features. It influenced the other major Western religions—Judaism, Christianity, and Islam.The ancients saw in Zoroastrianism the archetype of the dualistic view of the world and of man's destiny. Zoroaster was supposed to have instructed Pythagoras in Babylon and to have inspired the Chaldean doctrines of astrology and magic. It is likely that Zoroastrianism influenced the development of Judaism and the birth of Christianity. The Christians, following a Hebrew tradition, identified Zoroaster with Ezekiel, Nimrod, Seth, Balaam, and Baruch, and even through the latter, with Christ himself. On the other hand, Zoroaster, as the presumed founder of astrology and magic, could be considered the arch-heretic. In more recent times the study of Zoroastrianism has played a decisive part in reconstructing the religion and social structure of the Persian peoples.Though Zoroastrianism was never, even in the thinking of its founder, as aggressively monotheistic as for instance, Judaism or Islam, it does represent an original attempt at unifying under the worship of one supreme god, a polytheistic religion comparable to those of other early peoples.

The result today is the Shia schizoids, a sort of un-arab version of mohumedism.
