Zoroastrianism, the ancient Persian religion, is fundamentally monotheistic. It centers on the worship of **one supreme, uncreated God: Ahura Mazda** (Wise Lord), creator of all good, source of truth (Asha) and order.
Zoroastrianism acknowledges a hierarchy of divine beings — the **Amesha Spentas** (Bountiful Immortals: 6-7 attributes of Ahura Mazda like Good Mind, Truth, Devotion) and **Yazatas** (worthy of worship, e.g., Mithra, Anahita, Verethragna).
Crucially: These are **not independent gods**. They are:
This makes it **henotheistic** (worship of one supreme God while accepting other divine beings' existence) with **strong monotheistic theology**. It is **not polytheistic** (multiple independent gods).
Verdict: **Monotheistic** in core theology (One God, Ahura Mazda). **Henotheistic** in ritual structure (veneration of Amesha Spentas/Yazatas as divine aspects).
