470 - 500 WAR OF MAZDAISM VS. ZOROASTIANISM (Persia)
The Mazdaks named after its founder), also known as the Zandiks, were avowed “communists”, who banned marriage and property ownership. The Sassanids looked somewhat in favor of the Mazdaks since it weakened the nobles. The Zoroastrians, who were fire worshippers, defeated Kavad I, a mazdak , but he soon regained power in his own province. Many Jews were killed by both sides.
