The ancient Persian religion, primarily represented by Zoroastrianism, was founded by the prophet Zoroaster around the 6th century BCE. It emphasized the duality of good and evil, with the supreme god Ahura Mazda representing truth and light, while the evil spirit Angra Mainyu embodied chaos and darkness. Followers believed in the importance of individual choice and moral responsibility. Zoroastrianism also introduced concepts such as heaven, hell, and a final judgment, influencing later religions like Judaism, Christianity, and Islam. Rituals included prayers, fire worship, and the veneration of nature, reflecting a deep respect for the elements and the cosmos.
