Zoroastrianism sects

Zurvanism was a fatalistic religious movement of Zoroastrianism in which the divinity Zurvan is a first principle (primordial creator deity) who engendered equal-but-opposite twins, Ahura Mazda and Angra Mainyu. Zurvanism is also known as "Zurvanite Zoroastrianism", and may be contrasted with Mazdaism.

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