It is believed that during the reign of Nawab Shaista Khan the paik-peyada and clerical staff (kerani) of the Nawab used to live on the other side of the river Buriganga. Keraniganj is named after this.
It is assumed that during the period when Nawab Shaista Khan was in power, the staff responsible for the day-to-day operations (paik-peyada and kerani) of the Nawab lived on the opposite bank of the Buriganga River. The area now known as Keraniganj got its name from this.
