the end of August. History Medieval history Sultanpur is named after Chauhan Rajput raja Sultan Singh Chauhan, a great grandson of Harsh Dev Singh Chauhan. Harsh was one of 21 sons of king Sangat Singh Chauhan. Raja Sangat Singh was a great-grandnephew of king Prithviraj Chauhan (reign. c. 1178–1192 CE ) according to historical recorded by British raj Indian civil servant and historian Henry Elliot (1817-1907). Raja Sultan Singh Chauhan established Sultanpur in 1474 Vikram Samwat (1417 or 1418 CE) after wresting it from Silar Muslims. Silar Muslims, a branch of Oghuz Turks, originated from the invader Mahmud of Ghazni's (971 – 1030 CE) nephew Ghazi Saiyyad Salar Masud (1014 – 1034 CE) buried in Bahraich in Uttar Pradesh. Sultanpur was the biggest village (covering 52000 bighas of land) under Farrukhnagar and many of the present day villages around it have originated as dhanis i.e. temporary farmer's shelters within the "lal dora" revenue boundary of Sultanpur.

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. Salt was produced by extracting brine from about 40 saline water wells using bullocks and drying in open plots. Since salt was one of the major sources of Government revenue, the office of the salt superintendent at Sultanpur supervised the levy of ₹2 tax per maund. With the levy of the heavy salt tax and acquisition of the Sambhar, Rajasthan salt works in Rajputana by the British Indian Government the Sultanpur Salt became uneconomical and by 1903-04 the salt industry was struggling for survival with salt export having fallen to 65000 maunds leading to severe setback to the economy of the Sultanpur area.
