The Role of Quraish Tribe in Depriving Imam Ali (AS) from Islamic Caliphate

On the eve of Islam، Quraish tribe was the most significant Arab tribe. They had dominance on other tribes. This dominance continued after Islam too and left some effects on Islamic community. Though the Prophet Mohammad and Ali themselves came from Quraish، they were so much annoyed by them. Quraish chiefs and main figures were always making troubles during Ali''s Caliphate، because of unreasonable expectation and also because they lost their heroes in physical battles of first decades of Islam by Ali''s sword and because Imam Ali saw them like others people. Quraish chiefs firstly tried to prevent Ali''s Caliphate. Then after Ali’s Caliphate they played the key role in weakening his Caliphate. Based on an analytic-descriptive method، in this paper we try to find how Quraish chiefs played the key role in depriving Imam Ali (AS) from Islamic Caliphate.
