Hello AH.com I have a challenge for you guys today. With a POD anytime after the Islamic conquest have Zoroastrianism make a comeback inside of Persia. To succeed Zoroastrianism must have a majority within modern day Iran.
Note: Having Islam become extremely influenced by Zoroastrianism counts. But only if it is influenced to the point that it becomes Zoroastrianism with some Islamic beliefs tacked on.
