The region around Sultanpur was called Dhundhoti. Sultanpur was the center of salt production for use in Delhi and the United Provinces of British India till the late 19th century exporting annually 250000 quintals (680000 maunds) over the Rajputana-Malwa Railway. The Farrukhnagar railway station and metre-gauge railway train service was started on 14 February 1873, and there were a couple of railway sidings at Sultanpur for loading salt into the train wagons. Sultanpur had an ancient mosque dating back to the period of Sultan of Delhi, Ghiyas ud din Balban (1200–1287 CE). Two slabs of red sandstone bearing Arabic inscriptions taken from this mosque are fixed on the southern wall of the Jama Masjid at Farrukhnagar. The foundation of this mosque was clearly visible a few decades ago as per old residents of Sultanpur.
