Many historical evidences are presented about perception of the Iranian identity among clans and tribes at Gajar era. Clans and tribes of Iran communicate through the system of the oral cultural exchange to the various Iranian traditions.Such backgrounds cause these societies to form the most important soldier forces for defense of borders in the absence of army and modern military system. Although, existing interior convergence in the tribes and ethnics societies, variety, differences and distinctions among them, cultural poverty and expanded illiteracy, intense resistance against renovation and actually assimilation policy of Reza Shah Pahlavi, and as a result had been occurred wide tribal tensions, all of these, cause identity analyzers to pay attention to some evidences which confirm this theory that Iranian clans and tribes were social forces against government as well as anti-national, which lacks awareness and interests of Iranian identity. Such condition had been caused the relationship among tribes, clans and Iranian identity to be problematic. And we deal with this question: "how was the awareness of tribes and clans at Gajar era toward Iranian identity?" This study tries to find an appropriate answer to this question through historical study of the issue.
