Zoroastrism

Zoroastrianism, or more natively Mazdayasna, is one of the world's oldest extant 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), it exalts a deity of wisdom, Ahura Mazda (Wise Lord), as its Supreme Being. Major features of Zoroastrianism, such as messianism, heaven and hell, and free will have, some believe, 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 along with a Mithraic Median prototype and a Zurvanist Sassanid successor it served as the state religion of the from around 600 BCE to 650 CE. Zoroastrianism was suppressed from the 7th century onwards following the Muslim conquest of Persia of 633-654. Recent estimates place the current number of Zoroastrians at around 2.6 million, with most living in India and in Iran. Besides the Zoroastrian diaspora, the older Mithraic faith Yazdânism is still practised amongst Kurds.
