Bahadurgarh city was founded by Mughal Emperor Alamgir II, who was the Sultan of Delhi from 1754 to 1759. He gave the town in jagir to Bahadur Khan and Tej Khan, Baloch rulers of Farrukhnagar in 1754, who changed its name from Sharafabad to Bahadurgarh. They also constructed a Fort named Bahadurgarh Fort.
Bahadurgarh came into the hands of Sindhia in 1793. After Sindhia's defeat in 1803 at the hands of the British, Lord Lake transferred control of the town's government to the brother of the Nawab of Jhajjar.
