Iranian religions

The ancient Iranians made references to a combination of several Aryans and non-Aryan tribes.

The documented history of Iranian religions begins with Zoroastrianism.

[1] The Gathas, hymns of Zoroaster's Avesta, introduced monotheistic ideas to Persia, while through the Yashts and Yasna, mentions are made to polytheism and earlier creeds.

The Vedas and the Avesta have both served researchers as important resources in discovering early Proto-Indo-Iranian religion[2] beliefs and ideas,[3] the various beliefs and practices from which the later indigenous religion of the Iranian and Indo-Aryan peoples evolved.

Some religionists made syncretic teachings of Islam and local beliefs and cults such as Iranian paganism, Zurvanism, Manichaeism and Zoroastrianism.
