This religion was founded in ancient Persia, perhaps during the sixth and seventh century BCE. Many scholars believe that numerous religious concepts first appeared in Zoroastrianism, and were later adopted by Judaism, and then Christianity. These include: heaven, hell, resurrection of the body, the Messiah, final judgment, and the battle of Armageddon. Once a religion with many followers, it currently only has about 200,000 members; most live in Iran and India.
