Enough has been said of his public life, in that portion of the Annals of Mewar with which he was so closely connected, both by political and family ties. The Sayyids, who succeeded to power on the murder of their sovereign Farrukhsiyar, were too wise to raise enemies unnecessarily; and Jai Singh, when he left the unhappy monarch to his fate, retired to his hereditary dominions, devoting himself to his favourite pursuits, astronomy and history. He appears to have enjoyed three years of uninterrupted quiet, taking no part in the struggles, which terminated, in A.D. 1721, with Muhammad Shah’s defeat of his rivals, and the destruction of the Sayyids [360]. At this period Jai Singh was called from his philosophical pursuits, and appointed the king’s lieutenant for the provinces of Agra and Malwa in succession: and it was during this interval of comparative repose, that he erected those monuments which irradiate this dark epoch of the history of India.[9.2.12] Nor was he blind to the interests of his nation or the honour of Amber, and his important office was made subservient to obtaining the repeal of that disgraceful edict, the jizya, and authority to repress the infant power of the Jats, long a thorn in the side of Amber. But when, in A.D. 1732, the Raja, once more lieutenant for Malwa, saw that it was in vain to attempt to check the Mahratta invasion, or to prevent the partition of the empire, he deemed himself justified in consulting the welfare of his own house. We know not what terms Jai Singh entered into with the Mahratta leader, Bajirao, who by his influence was appointed Subahdar of Malwa; we may, however, imagine it was from some more powerful stimulant than the native historian of this period assigns, namely, “a similarity of religion.” By this conduct, Jai Singh is said emphatically, by his own countrymen, to have given the key of Hindustan to the Southron. The influence his character obtained, however, with the Mahrattas was even useful to his sovereign, for by it he retarded their excesses, which at length reached the capital. In a few years more (A.D. 1739), Nadir Shah’s invasion took place, and the Rajputs, wisely alive to their own interests, remained aloof from a cause which neither valour nor wisdom could longer serve. They respected the emperor, but the system of government had long alienated these gallant supporters of the throne. We may exemplify the trials to which Rajput fidelity was exposed, by one of “the hundred and nine deeds of Jai Singh” which will at the same time serve further to illustrate the position, that half the political and moral evils which have vexed the royal houses of Rajputana, take their rise from polygamy.
