Mazdakism

Mazdakism (Persian: مزدکیه) was an Iranian religion, which was an offshoot of Zoroastrianism.

The religion was founded in the early Sasanian Empire by Zardusht, a Zoroastrian mobad who was a contemporary of Mani (d. 274). However, it is named after its most prominent advocate, Mazdak, who was a powerful and controversial figure during the reign of Emperor Kavad I ((r. 498 – 531)).

Theology
Mazdakism was a dualistic religion that appeared to be influenced by Manichaeism. It taught that there were two principles, light and dark (good and evil) that merged at a primordial time creating the universe. The Mazdakites worshipped the God of Light.

Ethics
Mazdakism strongly promoted simple and pacifist living. Acts such as murder and killing animals for food or sport were forbidden, as was eating meat. Followers were to treat all people, even their enemies kindly. The movement also believed in the holding of all things in common to reduce greed.
