Zoroastrianism is one of the world's oldest monotheistic religions, founded by the prophet Zoroaster in ancient Persia around the 6th century BCE. It centers on the worship of Ahura Mazda, the supreme god, and emphasizes the duality of good and evil, human free will, and the eventual triumph of good over evil. The religion has significantly influenced other major faiths and highlights important aspects of religious diffusion through its historical spread and cultural interactions.
