Even though Mohammadreza Shah had always boasted that the Iranian Imperial Army was a formidable pillar of his power and spared no efforts to bolster its strength, the Army adopted an integrative policy with the overwhelming majority of people and was one of the most important elements which contributed to the success of the Islamic Revolution against the Pahlavi regime. The present study is an at- tempt to explore what contributed to the loyalty of the Iranian Imperial Army to the Islamic Rev- olution. It also takes an approach of historical sociology and is based on inductive methodology. After identifying the relevant variables and the association among them, the study offers a theo- retical model in order to explain why the Iranian Imperial Army joined and united with the revo- lutionary forces. The results showed that the factors fall into three broad categories, i.e. ideolog- ical, agency and structural. The ideological backgrounds had to do with the adherence of the personnel of the Army to Islamic teachings and getting inspired by the revolutionary ideology which were manifested in several instances. The agency backgrounds were concerned with the fact that the top commanders were obsequious to the Shah who held all the power which is a norm in monarchies. The structural backgrounds were about the patrimonial and centralized structure that the Army used to have which fostered the institutionalized and organized corrup- tion in the Army.
