3. Zoroastrianism (Ancient Persian Variant)
Once the official faith of the powerful Persian empires, ancient Zoroastrianism profoundly influenced later religious ideas about good, evil, and the afterlife. Its teachings emphasized the eternal struggle between the benevolent Ahura Mazda and the evil Angra Mainyu. Millions once followed its sacred fire rituals and moral codes. Although a small Zoroastrian community still exists, the original expansive religion has largely faded from prominence. Britannica on Zoroastrianism
