There are two views regarding the naming of Meherpur Pourasava. One, in the early 16th century a religious leader named Meher Ali Shah came to preach Islam in this area and founded his Durbar in the village Kalachandpur. Thereafter he founded another Durbar in the centre of "Barabazar" in this municipal town. From that time the preaching of Islam started in that Hindu-Buddha dominant society. It is presumed that in honour of the spiritual leader Meher Ali Shah, the area has been named as "Meherpur".
