The Bahraini crisis has particular geopolitical importance for regional and trans-regional powers regarding the limited ability of domestic actors and the interests of foreign actors in it. The present study aimed to examine the crisis in Bahrain and the religious and geopolitical conflicts between Iran and Saudi Arabia. To this aim, investigated the causes and roots of the conflicting approaches of the Islamic Republic of Iran and Saudi Arabia to the Bahrain crisis using the theoretical framework of constructivism and descriptive-analytical research methods. The results indicated that these conflicts began before the Islamic Revolution of Iran and culminated in the recent uprising of the Bahraini people. Iran and Saudi Arabia are two prominent regional actors in the Bahraini crisis that pursue active but conflicting approaches. This contradictory approach has caused severe tensions in Saudi Arabia's relations with the Islamic Republic of Iran.
