Coverage of the activities of Zarathushra in ancient written sources and questions of their interpretation.

The Zoroastrian religion and its holy book Avesta play a huge role in the study of the ancient history of Central Asia. In the Pahlavian sources, information relating to the Avestan texts, which have not been preserved to this day, has been preserved. They are greatly changed, but the value of this small part is very great. Based on written sources, parents, family members, classes and the place of propaganda of the prophet Zarathushtra were identified. Zoroaster was the Zaotar (the chief priest). The place and time of his birth, which require additional consideration, is still at the center of the discussion. He lived at the turn of the 2nd and 1st millennium BC on the territory of Central Asia. The territory of the spread of the Zoroastrian religion archaeologists associate with the culture of Jaz II. The culture of Yaz II is revealed in the territory of Northern Afghanistan, Uzbekistan, Turkmenistan and the south of Tajikistan (X-IX / VIII centuries BC)
