Answer:
Yes
Step-by-step explanation:
"In the matters of religion, it is well known that Darius was an adherent of Zoroastrianism or at least a firm believer of Ahura Mazda. This we can see in his inscriptions, where he attributes his success to Ahura Mazda, and in his legal system where all laws were created in the name of the Zoroastrian god. In the lands that were under Persian control, all other religions were tolerated as long as they remained submissive and peaceful."
