Baji Rao took a second wife, Mastani, the daughter of Rajput king Chhatrasal of Bundelkhand and his Muslim concubine. The marriage was political one, arranged to please Chhatrasal. Mastani had a son, Krishna Rao, in 1734. Since his mother was Muslim, the Hindu priests refused to conduct upanayana ceremony and he became known as Shamsher Bahadur. After the deaths of Baji Rao and Mastani in 1740, Kashibai raised six-year-old Shamsher Bahadur as her own. Shamsher received a portion of his father's dominion of Banda and Kalpi. In 1761, he and his army fought alongside the Peshwa in the Third Battle of Panipat between the Marathas and the Afghans. Wounded in the battle, Shamsher died several days later in Deeg.
