Where was zoroastrainism originated?

Zoroastrianism originated in ancient Persia, in the region that is now modern-day Iran. It was founded by the prophet Zoroaster (or Zarathustra) around the 6th century BCE, though some estimates suggest it may have been earlier. This religion emphasizes the duality of good and evil and the importance of individual choice in the battle between these forces. Zoroastrianism significantly influenced other major religions, particularly in concepts of heaven, hell, and the end of times.
