Zoroastrianism: An ancient
religion founded by Zarathushtra
"Zoroastrianism is the oldest of the revealed world-religions, and it
has probably had more influence on mankind, directly and indirectly, than any
other single faith." Mary Boyce.
The religion was founded by Zarathushtra in Persia, which is modern-day Iran. It may
have been the world's first monotheistic faith. It was once the religion of the
Persian empire, but has since been reduced in numbers to fewer than 200,000 today.
With the exception of religious conservatives, most religious historians believe the the Jewish, Christian and Muslim beliefs
concerning God and Satan, the soul, heaven
and hell, the virgin birth of the savior,
the slaughter of the innocents, resurrection, the final judgment, etc.
were all derived from Zoroastrianism.
