Ahura Mazda, whose name means "Wise Lord" or "Lord of Wisdom," stands as the supreme deity in Zoroastrianism, one of the world's oldest monotheistic religions founded by the prophet Zoroaster (Zarathustra) in ancient Persia, likely sometime between 1500-1000 BCE, though the exact dating remains debated. In Zoroaster's revolutionary theological vision, Ahura Mazda was proclaimed as the one uncreated, eternal God-the source of all goodness, truth, light, and order in the universe. This represented a dramatic departure from the polytheistic Indo-Iranian religious traditions that preceded Zoroastrianism. Ahura Mazda was understood as the creator of the material and spiritual worlds, embodying attributes such as wisdom, righteousness, and beneficence. He stood in cosmic opposition to Angra Mainyu (Ahriman), the destructive spirit representing chaos, falsehood, and evil, though crucially, Ahura Mazda was understood to be ultimately supreme and destined for final victory in this dualistic struggle between good and evil.
