Sultanpur is a district in the state of Uttar Pradesh in northern India. The district is a part of Faizabad Division. Its administrative headquarters is Sultanpur.
Around the 14-15th century, Rajkunwar branch of Chauhan Dynasty claiming to be direct descendent of Hammir Dev Chauhan of Ranthambore along with other clans like Bandalgotis, Rajwars and Bachgotis ruled over a large part of the district. In the 19th century, one notable incident was the revolt of the native troops stationed at Sultanpur during the Sepoy Mutiny after the British annexation of Oudh. The troops rose in rebellion on 9 June 1857, and, after murdering two of their officers, sacked the station. Native people and tribes like that of Bhale Sultans also fought in the rebellion. Leaders like Lal Pratap Singh of Kalakankar and Maharaj Bariar Singh Rajkunwar along with others fought and died for the cause. Upon the restoration of order, Sultanpur cantonment was strengthened by a detachment of British troops; but in 1861 it was entirely abandoned as a military station.
