Very few today know or care that Zoroastrianism is regarded as the first religion to teach monotheism, the belief in one supreme god, a cornerstone belief in Judaism, Christianity and Islam.

Zoroastrianism is also regarded as the first universal religion, meaning that it wasn’t a tribal faith like Judaism or the Egyptian religion, which were originally associated with one tribe, group of people or kingdom. From its inception Zoroastrianism aimed to convert people of all backgrounds and tribes. It welcomed outsiders and said that salvation was theirs if they embraced the religion. It was tolerant of other religions in that people were judged on the basis of their deeds not their faith.
