See it on the World Religions map →What it is
Tradition holds that Zarathustra, a priest in eastern Iran or Central Asia, received visions of Ahura Mazda ('Wise Lord') at about age 30. He taught that every person must choose between asha (truth and order) and druj (the lie), and that good would triumph at the end of time. Rejected at first, he won over a ruler named Vishtaspa. His own words are believed to survive in 17 hymns, the Gathas.
Why it matters
He is among the first known prophets to teach one supreme god, personal moral choice and a final judgment: ideas that may have shaped Judaism, Christianity and Islam.
Life, legacy and sources
The Gathas, whose archaic language closely resembles the Rigveda's and suggests an early date. Greek writers mention him; no inscription or contemporary record names him.
Questions and debates
Proposed dates run from about 1500 to 500 BC; many scholars favor c. 1200–1000 BC. His homeland, and what he taught versus later tradition, are debated.
Connections (3)
▸Zoroaster (Zarathustra) founded ZoroastrianismMostly agreed by scholars
The connection
Zoroaster reformed the older Iranian religion, a close cousin of the Vedic one, raising Ahura Mazda above all other divine beings and recasting the daevas, older gods, as demons. His Gathas set the faith's core: moral choice between truth and the lie. Followers built a full religion around it over centuries.
When and where
Eastern Iran or Central Asia, at a debated date, often put at c. 1200–1000 BC; tradition says he converted a local ruler, Vishtaspa.
How do we know?
The Gathas, attributed to Zoroaster himself, differ in language and outlook from the rest of the Avesta, suggesting a single founding voice.
Questions and debates
How much of later Zoroastrianism, with its priests and rituals, he would recognize, and whether he reformed or rejected the old religion.
▸Zoroaster (Zarathustra) was placed by Jaspers in The Axial AgeHistorical record
The connection
Karl Jaspers listed Zarathustra as Iran's great Axial Age teacher, alongside Confucius, the Buddha, the Hebrew prophets and the Greek philosophers. His teaching of personal moral choice between good and evil fit Jaspers's picture of an age that turned religion toward ethics.
When and where
Jaspers, The Origin and Goal of History, Germany, 1949; he followed the then-common dating of Zoroaster to around 600 BC.
Historical evidence
Jaspers names him explicitly. The fit is weaker than it once looked, because many scholars have since moved Zoroaster's dates earlier.
Questions and debates
If Zoroaster lived around 1200 BC, he predates the Axial Age by centuries, which raises questions about the theory itself.
▸Friedrich Nietzsche: 'God is dead' borrowed the name of Zoroaster (Zarathustra)Historical record
The connection
Nietzsche named his best-known book Thus Spoke Zarathustra (1883–85) after the Persian prophet. He chose him deliberately: as the first to make the struggle of good against evil a cosmic moral law, Zarathustra had to be the one to overcome that 'error'. The book's Zarathustra preaches the Übermensch, or 'overman', not Zoroastrian teaching.
When and where
Written in Italy, Switzerland and France (Nice), 1883–85; Nietzsche explained his choice of name in his autobiography Ecce Homo (written 1888).
Historical evidence
Nietzsche's own explanation in Ecce Homo and the book itself. The link is a borrowed name and symbol, not real influence from Zoroastrian scripture.
Questions and debates
How much Nietzsche actually knew about Zoroastrianism is unclear; he likely relied on secondhand 19th-century accounts rather than the Avesta itself.
