This paper is going to study the proceeding of coming into thrown and collapse of the first state of Ismaili in Subcontinent of India. Esmaili made their first endeavors from the end of the third century (A.H) when, due to the social and political situation of the region, their attempts were successful. The reports of different sources ascertain Esmaili’s rapid successes and welcome of the local governors and people of this region to their religion.
