In Raja Nahar Singh ascended the throne in 1829 after his father Ram Singh's death and proved to be a just ruler. Nahar Singh was ruler of 101 villages of Ballabhgarh. He, Nawab Ahmed Ali Khan of Farrukhnagar, and rulers of neighbouring principalities such as Rewari and Jhajjar, took part in the Indian Rebellion of 1857. On 10 September 1857, just four days before the British Army stormed Delhi, Nahar Singh wrote a letter to Governor General of India, Lord Ellenborough (1842–1844), whom he had met as a young man, seeking his protection. According to a 2011 auction catalogue, "it seems was written as a ruse to deceive the British in the event of his capture... as he was fully committed to the cause of Indian Independence".
