Prithvi Singh was Jaswant Singh's son. It is chronicled in [[Marwar]] ''khyats'' that Aurangzeb presented Prithvi Singh a dress which was poisoned. On wearing this dress Prithvi died in great pain. Prithvi was a good leader and a brave prince. Jaswant could not get over the shock of his son's death. He was very saddened because he had no male heir who could seek revenge. Jaswant died in [[1680]]. [[James Tod]] writes in his '''Annals and Antiquities of ancient Rajasthan:'''
:''"Sighs never ceased flowing from Aurang’s heart while Jaswant lived. . . had all the princely contemporaries of Jaswant- Jai Singh of [[Amber]], Rana Raj Singh of [[Mewar]], and Chattrapati [[Shivaji]] coalesced against their national foe, the Mughal power would have been made extinct. Could Jaswant, however, have been satisfied with the mental wounds he inflicted upon Aurangzeb, he would have had ample revenge; for the image of the Rathore crossed all his visions of aggrandizement. The cruel sacrifice of his heir, and the still more barbarous and unrelenting ferocity with which he pursued Jaswant’s innocent family, are the surest proofs of the dread which the Rathore prince inspired while alive."''
