The research major question is: how Iranian identity elements (especially religion) changes define by resistance identity theoretical framework, in first and second Hejry decades? Research theoretical model is a composing of notions of Giddens’s structuration theory, Castells’s resistance identity theory and Ahmadi’s historical sociology theory, and using them in the survey on the Iranian social movement's identity behavior, in the first and second Hejry decades.
The research results show that the Iranian's identity changes, had been not happened under Arab's imposition or compulsion, after Iranians and Sassanid's government defeat. Iranian's identity changes had been done under a long process under a determinant and fundamental choice by Iranians, in oppose and resistance, against Arab governor's compulsions.
