Zoroastrianism affected the way the Persians governed their
subjects by allowing the territories under their rule to worship their own
religion. Many of the Persian Monarchs like Cyrus the Great were deeply devoted
to Zoroastrianism and never imposed it on the places that they have
conquered. They were very tolerant about
other people’s faiths. This tolerance and kindness had a deep effect on other
religions. It also shared some common
beliefs with religions like Judaism, Christianity and Islam especially when it
comes to the concept of worshipping one deity.
