Wrong again.
The Persian caiphates were Theocratic Monarchies.
The Umayyad and Abbasid Caliphates were
Arab rulers, as I have already told you, not Persian!!!
Try again... I understand this stuff, and as a well known member of this forum sometimes says.. "You can Google for infomation, but you cannot Google for understanding."
I don't believe you understand this at all. Even the reference to Googling implies that that is how YOU get your information.
On the other hand, I have read a number of
books about Iran, such as this one...
And what do we find on page 71 at the beginning of the chapter on Islam and Invasions: The Arabs, Turks and Mongols....
Look at the bit I have underlined where it says that the monarchy and Zoroastrian religion were swept away, while the language and Persian poetry survived.
On page 78-79, we read that Iran was ruled over by foreign rulers under the Umayyad and Abbasid Caliphates...
So why not stop with this posturing BS about how learned you are. I very much doubt anyone is taking your claims to expertise very seriously.
I don't claim to be any kind of expert either, but I obviously know more than you do, which is not difficult at all, to be fair.
