Because of its location on an important east–west trade route, Nabiganj historically served as a way station for travelling merchants. A roadside sarai built by Khan Bahadur Khan, who ruled at Karimganj in the mid-1700s, offered lodging to travellers into the early 20th century. At one point, Nabiganj was the seat of a pargana; it was later merged under Kishni. In the early 1800s, the local zamindars were Bais Rajputs; in 1840, they sold the village to a group of Chauhans from Bhadai, Chirawar, and Arjunpur.
