Zoroastrianism. History

HISTORY
Zoroastrianism is one of the world’s oldest known living religions and has its origins in the distant past. It developed about three and a half thousand years ago from the ancient Indo-Iranian religion that was once shared by the ancestors of nomadic herding tribes that later settled in Iran and northern India.

WHAT DO ZOROASTRIANS BELIEVE?
They believe that their religion was revealed by Ahura Mazda to a priest called Zarathustra.
Central to Zoroastrianism is the profound dichotomy between good and evil and the idea that the world was created Ahura Mazda, in order that the two forces could engage with one another and the evil one will be incapacitated.

HOLY BOOKS
Zoroastrian holy book is called the Avesta. It includes the original words of their founder, preserved in a series if five hymns, called the Gathas. The Avesta often resembles a prayer book and has few narratives.
