Zoroastrianism

Zoroastrianism, or more natively Mazdayasna, is one of the world's oldest religions, "combining a cosmogonic dualism and eschatological monotheism in a manner unique... among the major religions of the world." Ascribed to the teachings of the Iranian Prophet Zoroaster (or Zarathustra), he exalted their deity of wisdom, Ahura Mazda, as its Supreme Being. Leading characteristics, such as messianism, heaven and hell, and free will influenced other religious systems, including Second Temple Judaism, Gnosticism, Christianity, and Islam. With possible roots dating back to the second millennium BCE, Zoroastrianism enters recorded history in the 5th-century BCE, and including a Mithraic Median prototype and Zurvanist Sassanid successor it served as the state religion of the pre-Islamic Iranian empires from around 600 BCE to 650 CE. Zoroastrianism was suppressed from the 7th century onwards following the Muslim conquest of Persia. Recent estimates place the current number of Zoroastrians at around 2.6 million, with most living in India and Iran. Besides the Zoroastrian diaspora, the older Mithraic faith Yazdânism is still practised amongst the Kurds.
