The actions of Nadir corresponded with these declarations. He sent an officer to Constantinople, the duties of whose mission to the Emperor Mahmud were limited to this short message: "Restore the provinces of Persia or prepare for war." A messenger was deputed to Achmet, the Pacha of Bagdad, to apprise him that "the deliverer of Persia" was approaching. A peace had been concluded with the Russians, by which it was stipulated that they should abandon all the conquests they had made on the shores of the Caspian; and Nadir despatched two officers to that quarter to see that there was no delay in the execution of this treaty. After adopting these measures Nadir marched to Ispahan. He first upbraided Shah Tamasp, and then pretended to be reconciled to him; but the scene of his mock submission to this Prince drew to a close. Tamasp was invited to the tents of his general to share in the joys of a feast, which terminated in his being seized and dethroned. He was sent to Khorasan. The Mahometan author who records these events is careful in informing us that the generosity of Nadir desired that Tamasp, though a prisoner, should be accompanied by all his ladies, and enjoy every other comfort that could be deemed necessary to pleasurable existence. The time did not yet appear to Nadir to be ripe for his seizing the crown of Persia. The officers of his army and some venal nobles of the court earnestly requested that he, who was alone worthy to wear the diadem, would place it upon his head; but he rejected their entreaties, from pretended respect for the blood of the Suffavean kings. The son of Tamasp, an infant only eight months old, was seated upon the throne, and Nadir accepted the name and power of regent of the empire.
