The lord Sasan who is named as the eponymous ancestor of the Sasanians took, according to Tabari, a wife from a family called "Bazrangi".
[1][2] In the account of Tabari, Ardashir, the founder of Sassanid dynasty was sent for educational reasons, at the request of his father Papak, to Tīrī who was the eunuch of Gōčehr the king of Eṣṭaḵr.
Ardashir managed to make a number of local conquests and then wrote to his father to revolt against Gōčehr.
[2] There is a suggestion by S. Wikander that Bāzrang is not a name but rather a title with the etymology of "holding a mace", or "possessing miraculous power".
[2] The word Bāzrang has been used in other historical sources, such as Eṣṭaḵrī, to refer to a geographical district in the mountainous BoyerAhmad area where the Šīrīn and Šāḏkān rivers have their origin.
