One of the basic issues in the realm of shii history is its evolutional course thatunfortunately have not been deservingly paid attention to it. Shiism in its longhistory have presented an evolutional course, valuable to study and research moreabout it.

One of the bright points in shii history is Mogul era (756-654.H). Acording tomany historians shiism have obtained a lot of successes in this era. surely manyfactors have been effective in this regard that the most important of them are: firstlythe collapse of Ismaili government in AlAmoot. AlAmoot was a powerful rival forImami shiis and also a defaming factor for all shii orders. Secondly the abolishing ofAbbasid Caliphate that as a powerful centre for sunni Islam was an importantobstacle in developing the propagandistic activities of Imamis. Thirdly the religiousenegligence of Moguls that opened the way for increasing the propaganda of Imamis.Fourthly the rivalry and hostility of Moguls with sunni Mamalik of Egipt. Opositionof shiis with Caliphate of cairo was an important factor in friendly behavior ofMoguls with shiism and shiis. And lostly the presence to shii political and religouselites in Mogul government and their cooperation with it. They had a considerablerole in turning Moguls toward shiis.

Of course another factors have been effective in this regard that we can notconsider them have.
