Zoroastrian philosophy

Mazdak (, , also known as Mazdak Bamdadan; died c. 524 or 528) was an Iranian mobad (priest) and social reformer who rose to prominence during the reign of the Sasanian emperor Kavadh I. He instituted a religious and social movement known as Mazdakism, which preached a dualistic cosmology and social welfare programs, including the communal ownership of property and, controversially, women (interpreted by some scholars as a reaction against the harem system).
