Upon the death of his father, Samrath Singh, in 1754, he succeeded him as the Rao of Sikar.[1] He was disliked by the people due to his ineffectiveness as a ruler.[1][2] This allowed his uncles, Chand Singh and Budh Singh, to occupy Sikar in 1756 and depose him as its ruler.[1] Later, Nahar Singh attempted to reclaim Sikar, but he was defeated by his uncles.[1] A compromise was reached between him and his uncle, through which certain estates were granted in perpetuity to him and his brothers, thereby resolving the feud.[1][2] He himself received Balaran for his maintenance.[3]
