Mazdakism

Overview
Mazdakism (Persian: مزدکیه, romanized: mazdakīye) was an Iranian religion, which was an offshoot of Zoroastrianism.
The religion was founded in the early Sasanian Empire by Zaradust-e Khuragen, 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), until he was killed by Emperor Khusrau I (r. 531–579).
