It's a pity this is not pushed further. The Turkish nationalists in the 20s wanted to promote shamanism to kick out islam and the Egyptians in the late 1800s were involved in pharoanism..
The Kurds were the Medes.
The Medes had an Ancient Iranian Religion (a form of pre-Zoroastrian Mazdaism or Mithra worshipping) with a priesthood named as “Magi”. Later and during the reigns of last Median kings the reforms of Zarathustra spread in western Iran.
LONG before there was an Iran. Why they stated it this way is misleading.
