The 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 Sindia'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. During 1995-1998, a series of rapes and murders of young girls by the Bahadurgarh baby killer led to several dharnas and bandhs by the local population. The police prosecuted three men as the "baby killer", before the real culprit was caught in November 1998.
Bahadurgarh is located in the Jhajjar district in the Indian state of Haryana and is situated in the eastern part of the state, and northern part of the country. The city is located on the border with New Delhi (commonly known as Tikri Border). References From:-wikipedia
