Zoroastrianism is the ancient religion of Persia. It was founded about 3500 years ago by the prophet Zarathushtra. Arising out of the polytheistic traditions of ancient India and Iran, he was one of the first monotheists in human history. Zarathushtra preached that there was one God, whom he called Ahura Mazda. Ahura means "Lord," and Mazda means "Wise," so Zoroastrians call God the "Wise Lord." Zarathushtra has been known in the West as Zoroaster, from the Greek transliteration of his name; in Persia and India he is known as Zarthosht.
