The Role of Shiism in the Foreign Policy of the Islamic Republic of Iran

The Iranian Revolution of 1979 caused Iran to shape its foreign policy along with its domestic political structure, within the framework of a certain Shiite understanding of Islam. Within this context and through the use of the explanatory case study method, this study aims to examine the effect of Shiism within the foreign policy of the post-Revolution Islamic Republic of Iran. First, the foreign policy-making process of the Islamic Republic of Iran and its various elements were discussed within the framework of the views of the Republic’s founder, the Supreme Leader Khomeini. Second, the effect of Shiism within and on Iranian foreign policy and affected regions will be explored and discussed. This study reports that Shiism is the most significant determining element in Iran’s foreign policy following the 1979 Revolution, that the country’s foreign policy approaches are not entirely Shiism-oriented, that there are deviations from this strictly Shiite approach, and that Iran’s foreign policy also includes realpolitik approaches.
