13 years ago I had many Iraqi students. Some were yazidi. They were very interesting. They spoke Kurdish, but were equally persecuted by Sunni Shia and Christians.

In their story, they are directly descendent of one of Noah's sons.... And you can not join their faith or marry into it.

The believe that Gods chief angel (lucifer) was never kicked out to be a fallen angel. He is depicted as an angel with peacock wings. They believe that God god died in battle and his head angel has taken the responsibility for gods creation in his absence.

These people will wear peacock necalace rather then a cross, Star of David or cresent.
