`Anthropology, history and Roger Savory==  Ali, here is the definition of anthropology: :Anthropology is the study of the anatomical and mental composition of humanity through the examination of historical and present geographical distribution, cultural history, acculturation, cultural relationships, and racial classifications. So indeed Tapper is equivalent if not more authoritative source on history as well as origins of Iranian dynasty. His comprehensive studies and several articles published on Shahsevans serve as an excellent proof of his scholarly capability. As I do not, like yourself, pretend to be a judge which scholar is better, more or less authoritative, we shall go equivalently with all quotes provided. Now pertaining to your generalization that Safavids were of Kurdish origin per ``consensus of scholars``, I would like to bring your attention to the following text, from your favourite source, Roger Savory, ``The Office of Khalīfat Al-Khulafā under the Ṣafawids``, Journal of the American Oriental Society, Vol. 85, No. 4. (Oct. - Dec., 1965), pp. 497): :The ``curious office`` of khalifat as-khulafa was, in Minorsky's phrase, a ``survival of the basic organization of the early Safavids, very similar to the single party of a modern totalitarian state``. The ``nucleus staff`` of the Safawid order comprised ``a khalifat al-khulafa, an abdal, a dada, a khadim  ... besides his lala 'governor, tutor',`` :The office of khalifat al-khulafa is felicitiously called by Minorsky the ``special secretariat for Sufi affairs``. Through the khalifat al-khulafa and the Sufis, he says, Shah contrlled not only the forces which brought them to power, but also the network of their adherents in Asia Minor. '''Since the Sufis were qizilbash and mostly Turks - or rather Turcomans - it follows that the holder of the office of khalifat al-khulafa was necessarily a qizilbash and usually a Turcoman. I don't see the word Kurdish in their, and office of khalifat al-khulafa as essential element of Safavid order and dynasty shall be incorporated into the article as shown above from Roger Savory. And please, do not rush to incorporate your updates on Kurdish origin claims and rejection of Shah of Azerbaijan quote. We need to come to consensus as you well know. Thanks.    ==`
